Numerous legislative measures were introduced in the 117th Congress to address the health and 
  
disability compensation concerns of veterans potentially exposed to toxic substances during 
military service. The culmination of this effort was the Sergeant First Class Heath Robinson 
 
Honoring our Promise to Address Comprehensive Toxics Act of 2022, or the Honoring our 
PACT Act of 2022 (P.L. 117-168), which President Biden signed into law on August 20, 2022. The Honoring our PACT Act 
of 2022 contains nine titles. As part of a series of CRS reports on various provisions in the Honoring our PACT Act of 2022, 
this report focuses on Title I and Section 603 of Title IV. 
Title I (Conceding Our Veterans’ Exposure Now and Necessitating Training Act of 2022, or the COVENANT Act of 2022) 
of the Honoring our PACT Act of 2022 expands health care eligibility via two major pathways. The first expands access to 
health care through the Veterans Health Administration (VHA) for specific categories of veterans exposed to toxic 
substances, and the second expands the health care enrollment period for certain veterans of combat service. For purposes of 
this report, unless otherwise specified, the Secretary refers to the Secretary of Veterans Affairs (VA). 
The first pathway includes three different authorities: 
1.  The act authorizes the Secretary to provide hospital care (including mental health services and counseling), medical 
services, and nursing home care for any illness, unless there is insufficient medical evidence to conclude that the 
illness is attributable to such service, to a veteran who participated in a “toxic exposure risk activity” while serving 
on active duty, active duty for training, or inactive duty training. A “toxic exposure risk activity” means any activity 
that requires a corresponding entry in the Individual Longitudinal Exposure Record (ILER) of the veteran who 
carried out the activity, or any activity that the Secretary “determines qualifies for the purposes of this subsection” 
(e.g., hospital care, medical services, and nursing home care) to reasonably protect the health of veterans.  
2.  The act authorizes the Secretary to provide hospital care (including mental health services and counseling), medical 
services, and nursing home care for any illness, unless there is insufficient medical evidence to conclude that the 
illness is attributable to such service, to any veteran who, on or after August 2, 1990, performed active military, 
naval, air, or space service while assigned to a duty station in, including airspace above, Bahrain, Iraq, Kuwait, 
Oman, Qatar, Saudi Arabia, Somalia, or United Arab Emirates; or who, on or after September 11, 2001, performed 
active military, naval, air, or space service while assigned to a duty station in, including airspace above, 
Afghanistan, Djibouti, Egypt, Jordan, Lebanon, Syria, Yemen, Uzbekistan, the Philippines, or any other country 
determined by the Secretary. 
3.  The act authorizes the Secretary to provide hospital care (including mental health services and counseling), medical 
services, and nursing home care for any illness, unless there is insufficient medical evidence to conclude that the 
illness is attributable to such service, to a veteran who was deployed for any of the following contingency 
operations: Operation Enduring Freedom, Operation Freedom’s Sentinel, Operation Iraqi Freedom, Operation New 
Dawn, Operation Inherent Resolve, or Resolute Support Mission. 
On February 26, 2024, VA announced that it will be eliminating the phase-in enrollment dates under Section 103 of the 
Honoring our PACT Act of 2022 (that is, between October 1, 2024, and October 1, 2032) of the above three statutory 
categories, and accepting and processing applications for enrollment in the VA health care system from all eligible veterans 
under the PACT Act beginning March 5, 2024.  
The second pathway expands the period of eligibility for enrollment in the VA health care system for certain combat service 
veterans. The act extends the period of enrollment in the VA health care system from 5 to 10 years. Veterans who served 
between September 11, 2001, and before October 1, 2013, but who prior to the act could not enroll during the five-year 
period of post-discharge eligibility, were granted an additional one-year period of enrollment eligibility beginning on October 
1, 2022. Furthermore, the act clarified that service in the “Persian Gulf War” includes any veteran who, during such period of 
service, received the Armed Forces Expeditionary Medal, Service Specific Expeditionary Medal, Combat Era Specific 
Expeditionary Medal, Campaign Specific Medal, or any other combat theater award established by a federal statute or an 
executive order. The enrollment expansion became effective on October 1, 2022. The above criteria also applies to National 
Congressional Research Service 
 
Honoring our PACT Act of 2022 (P.L. 117-168) 
 
Guard and Reserve personnel who were called to active duty by federal executive order and who served in a theater of 
combat operations after November 11, 1998.  
Section 603 of Title VI (Fairly Assessing Service-related Toxic Exposure Residuals Presumptions Act of 2022, or the 
FASTER Presumption Act of 2022) required VA to implement toxic exposure screening of all enrolled veterans to help 
determine potential toxic exposures during active military, naval, air, or space service. VA implemented toxic exposure 
screenings on November 8, 2022.

Introduction 
On August 10, 2022, President Biden signed into law the Sergeant First Class Heath Robinson 
Honoring our Promise to Address Comprehensive Toxics Act of 2022, or the Honoring our PACT 
Act of 2022 (P.L. 117-168). The act marked the culmination of a legislative effort, spanning 
several congresses, to comprehensively address health care eligibility and disability compensation 
policies for veterans exposed to a wide variety of occupational and environmental hazards during 
military service. Over the years, as evidenced by numerous Senate and House Veterans’ Affairs 
Committee hearings and studies,1 Congress and the Department of Veterans Affairs (VA) have 
grappled with how to provide disability compensation and eligibility for health care to veterans 
with illnesses and disabilities related to, or possibly related to, environmental or occupational 
exposures. 
Providing this type of disability compensation and health care eligibility to veterans can be 
challenging; for example, when the scientific evidence is incomplete, when the association 
between environmental exposure and illness is unclear, and when other factors (e.g., natural 
aging, family history, and lifestyle habits) might contribute to the illness or disability. In other 
words, incorporating “science into difficult and contentious veteran compensation policy 
decisions”2 is hard, especially when considering environmental exposures during deployment and 
“latent diseases allegedly associated with exposures many years earlier.”3 Given these challenges, 
Congress “has taken a piecemeal approach to addressing military exposures.”4 
From time to time, Congress has passed legislation related to care and benefits for former 
prisoners of war, service in Vietnam, exposure to ionizing radiation, service during the Persian 
Gulf War, contaminated drinking water at Camp Lejeune North Carolina, and Blue Water Navy 
Vietnam veterans, among other legislative efforts.  
In response to mounting concerns about the use of open burn pits during Operation Iraqi Freedom 
(OIF) in Iraq and Operation Enduring Freedom (OEF) in Afghanistan, and the potential impacts 
on the health of veterans who served at or near open burn pit sites in Afghanistan and the

P.L. 109-163, see 38 U.S.C. §1101 notes) examined benefits for veterans exposed to environmental/occupational 
hazards and—because “an increasing proportion of benefits is paid through a presumptive decision-making process”—
tasked the then-Institute of Medicine (IOM; since 2015 known as the National Academy of Medicine [NAM], part of 
the National Academies of Sciences, Engineering, and Medicine [NASEM]) to examine the presumptive 
decisionmaking process and “recommend a framework that would rely on scientific principles.” Veterans’ Disability

Southwest Asia theater of operations,5 Congress passed legislation to study the potential health 
effects associated with exposure to open burn pit emissions during deployment. The earliest 
legislation to do so was the Dignified Burial and Other Veterans’ Benefits Improvement Act of 
2012 (P.L. 112-260), which authorized VA to establish a registry of veterans and current 
servicemembers who may have been exposed to “toxic airborne chemicals and fumes caused by 
open burn pits”6 within one year after enactment. Moreover, H.Rept. 115-929 to accompany the 
Energy and Water, Legislative Branch, and Military Construction and Veterans Affairs 
Appropriations Act, 2019 (H.R. 5895; P.L. 115-244), required VA to rename the Airborne Hazards 
Center of Excellence (AHCE) at the War Related Illness and Injury Study Center as the Airborne 
Hazards and Burn Pits Center of Excellence, and to focus on clinical, translation research, and 
education pertaining to airborne hazards and open burn pit exposure-related concerns of 
veterans.7 In 2009, VA requested the then-Institute of Medicine (IOM; now the National Academy 
of Medicine of the National Academies of Sciences, Engineering, and Medicine [NASEM]) to 
assess “the potential long-term health effects of exposure to burn pits in Iraq and Afghanistan,” 
and to examine the feasibility and design of a long-term epidemiological study of veterans 
exposed to burn pit emissions.8 NASEM issued its report in October 2011. According to the 
report findings, among other conclusions,  
...  service  in  Iraq  or  Afghanistan—that  is,  a  broader  consideration  of  air  pollution  than 
exposure only to burn pit emissions—might be associated with long-term health effects, 
particularly in highly exposed populations (such as those who worked at the burn pit) or 
susceptible populations (for example, those who have asthma), mainly because of the high 
ambient concentrations of PM [particulate matter] from both natural and anthropogenic, 
including  military,  sources.  If  that  broader  exposure  to  air  pollution  turns  out  to  be 
sufficiently  high,  potentially  related  health  effects  of  concern  are  respiratory  and 
cardiovascular effects and cancer.9 
The NASEM report further recommended a well-designed epidemiologic study of the potential 
health effects of environmental exposures among U.S. military personnel and veterans who were 
deployed at burn pit sites. It further noted that determining the incidence of chronic diseases or 
cancers with long latency periods would require tracking study subjects for many years.10 
The Dignified Burial and Other Veterans’ Benefits Improvement Act of 2012 (P.L. 112-260) 
further required independent assessments of the Airborne Hazards and Open Burn Pit Registry 
(AHOBPR) that was established by VA in June 2014 and a follow-up report not later than five 
years after completion of the initial report.11 VA contracted with NASEM to evaluate the registry. 
 
5 The VA defines the Southwest Asia theater of operations as “Iraq, Kuwait, Saudi Arabia, the neutral zone between 
Iraq and Saudi Arabia, Bahrain, Qatar, the United Arab Emirates, Oman, the Gulf of Aden, the Gulf of Oman, the 
Persian Gulf, the Arabian Sea, the Red Sea, and the airspace above these locations” (38 C.F.R. §3.317(e)(2)). Also see

The law required that the assessment include, among other things, “recommendations regarding 
the most effective and prudent means of addressing the medical needs of eligible individuals with 
respect to conditions that are likely to result from exposure to open burn pits”12 Among other 
findings, the initial report “concluded that the exposure data are of insufficient quality or 
reliability to make them useful in anything other than the most general assessments of exposure 
potential.”13 As required by P.L. 112-260, NASEM conducted another reassessment of the 
AHOBPR, and its findings were released in October 2022. The findings concluded that “the 
stated registry purposes of ‘research about potential health effects of airborne hazards’ and 
conducting population health surveillance are unattainable, that data collection to meet these 
purposes is not helpful, and that efforts to address these important functions could be pursued in 
other, more effective ways.” NASEM recommended that VA initiate a new phase for the 
AHOBPR.14 
In September 2018, VA requested NASEM to study the health effects of airborne hazards and 
respiratory health outcomes in veterans who participated in military operations in Southwest Asia. 
The NASEM study committee developed a list of 27 respiratory health outcomes to review, such 
as respiratory cancers, asthma, chronic bronchitis, chronic obstructive pulmonary disease, 
emphysema, chronic persistent cough, shortness of breath (dyspnea), and wheezing, and released 
its findings in September 2020. Among its findings, the NASEM study committee concluded that 
of the 27 respiratory health outcomes examined, only chronic persistent cough, shortness of 
breath (dyspnea), and wheezing met the criteria for limited or suggestive evidence of an 
association,15 and that the remaining 24 conditions had inadequate or insufficient evidence to 
determine an association.16 In testimony before the House Veterans’ Affairs Subcommittee on 
Disability Assistance and Memorial Affairs, NASEM stated 
It is clear that military personnel and veterans are experiencing respiratory health problems, 
and  our  committee  [Committee  on  the  Respiratory  Health  Effects  of  Airborne  Hazards 
Exposure in the Southwest Asia Theater of Military Operations] wishes to emphasize that 
these findings do not mean that there is no association between service in the Southwest 
Asia  theater  and  these  conditions.  Instead,  the  committee  found  that  the  available 
epidemiologic evidence does not allow a definitive determination to be made about any 
potential association.17

limited by an inability to confidently rule out chance, bias, or confounding.” (Source: Respiratory Health Effects of

Honoring our PACT Act of 2022 (P.L. 117-168) 
 
Frustrated by a persistent lack of scientific evidence to link certain diseases or conditions with 
environment exposures during military service, veterans turned to Congress for legislation that 
would enable them to obtain VA medical care and disability compensation.  
Brief Legislative History 
At the start of the 117th Congress, the House and Senate Veterans’ Affairs Committees (HVAC 
and SVAC, respectively) made veterans’ exposure to toxic substances a legislative priority.18 
Although numerous measures were introduced in the 117th Congress to address the health and 
disability compensation concerns of veterans potentially exposed to toxic substances, the HVAC 
and SVAC began drafting legislation that incorporated various provisions of multiple stand-alone 
bills.19 
On June 17, 2021, then-Chairman Mark Takano of HVAC introduced the Honoring our Promise 
to Address Comprehensive Toxics Act of 2021, or the Honoring our PACT Act of 2021 (H.R. 
3967). A markup of the bill was held on June 24, 2021. The text of H.R. 3967, as ordered reported 
(H.Rept. 117-249 Part 1) by the Committee on Veterans’ Affairs, with modifications, was then 
included in House Rules Committee Print 117-33. Following floor debate, the House passed an 
amended version of the bill on March 3, 2022.20 On October 19, 2021, Chairman Jon Tester of 
SVAC reported the Comprehensive and Overdue Support for Troops of War Act of 2021, or the 
COST of War Act of 2021 (S. 3003), to the Senate. In the meantime, SVAC Chairman Jon Tester 
and ranking member Jerry Moran decided on a “three-step approach” to address issues pertaining 
to health care, disability compensation, and presumptive service-connection.21 To address health

care eligibility as a first step, on February 1, 2022, the chairman and ranking member introduced 
the Health Care for Burn Pit Veterans Act (S. 3541), which passed the Senate by unanimous 
consent on February 16, 2022. Compared with the COST of War Act of 2021 (S. 3003), the 
Health Care for Burn Pit Veterans Act (S. 3541) focused on extending the period of enrollment in 
the VA health care system for veterans who served in a theater of combat operations. As Senator 
Tester stated during Senate consideration of S. 3541, “It expands the screening period of 
healthcare eligibility for combat veterans who served after September 11, 2001, from 5 years to 
10,” and “provides an open enrollment period for any post-9/11 combat veteran who is more than 
10 years from separation.”22  
On May 24, 2022, SVAC Chairman Jon Tester and ranking member Jerry Moran released the text 
of the SVAC version of the Sergeant First Class Heath Robinson Honoring Our Promise to 
Address Comprehensive Toxics (PACT) Act of 2022 that addressed the latter two steps and 
included provisions related to health care, disability compensation, and presumptive service-
connection among other provisions.23 On June 8, 2022, the text of the measure was proposed by 
Senator Tester as S.Amdt. 5051 to H.R. 3967,24 and it passed the Senate on June 16, 2022.25 
Among other provisions, the Senate-passed version included several provisions that would affect 
VA employee compensation, including the authority to buy out the service contracts of health care 
professionals to whom VA has offered employment at rural or highly rural VA facilities. These 
service contract buyouts were to be exempt from taxation. Since the Origination Clause in the 
U.S. Constitution (Article 1, Section 7) requires that revenue bills originate in the House and 
specifies that the Senate may not propose any amendment that would raise revenue to a House-
passed nonrevenue measure this tax-exempt provision created what is known as a “blue-slipping” 
issue.26 The House then took up an unrelated measure previously passed by the Senate (S. 3373), 
included the text of the Sergeant First Class Heath Robinson Honoring our Promise to Address 
Comprehensive Toxics Act of 2022, excluded the tax-exempt provision, and passed it on July 13, 
2022.27 The Senate agreed to the House amendment to S. 3373 and passed the measure on August 
2, 2022.28 The bill was signed by the President on August 10, 2022.29

Honoring our PACT Act of 2022 (P.L. 117-168) 
 
Cost of War Toxic Exposures Fund (TEF) 
Section 805(a) of the Honoring our PACT Act of 2022 (P.L. 117-168) established the Cost of War 
Toxic Exposure Fund (TEF), to be administered by the VA Secretary.30 The act appropriated $500 
million for the TEF for FY2022, to remain available until September 30, 2024. The act further 
authorizes appropriations (such sums as are necessary) to the fund for FY2023 and each 
subsequent fiscal year for costs associated with the delivery of health care associated with 
environmental hazards during active military service. Moreover, funds from the TEF are to be 
used for costs associated with medical and other research related to environmental hazards, along 
with administrative expenses related to benefits, including information technology, benefit claims 
processing, and adjudicating appeals from veterans.31 Appropriations provided for the TEF shall 
be considered “direct spending” and treated as an “appropriated entitlement” (see text box 
below). Furthermore, the fund is exempt from mandatory sequestration provisions in Section 
256(h) of Balanced Budget and Emergency Deficit Control Act of 1985 (BBEDCA), as amended.  
The Honoring our PACT Act of 2022 also required VA to submit to the Senate and House 
Appropriations Committees a spend plan for how the department plans to obligate the $500 
million made available under Section 806 of the act. The Consolidated Appropriations Act, 2023 
(P.L. 117-328), provided $5.0 billion in mandatory (direct) funding for TEF, to remain available 
until September 30, 2027. These funds would be used for new costs associated with eligibility 
expansions authorized in the Honoring our PACT Act of 2022 (P.L. 117-168). According to 
explanatory statement accompanying the Consolidated Appropriations Act, 2023, there is no shift 
in discretionary appropriations to the TEF.32 The Fiscal Responsibility Act (FRA) of 2023 (P.L. 
118-5), among other things, provided funding for TEF. The act provided $20.27 billion in 
mandatory funding that became available on October 1, 2023, and will remain available until 
September 30, 2028, and $24.46 billion, in mandatory funding, which will become available on 
October 1, 2024, and will remain available until September 30, 2029. 
Based on statute and VA’s Financial Policy documents:  
The PACT Act authorizes funds to be appropriated beginning in fiscal year (FY) 2023, and 
for each subsequent FY, such sums as are necessary to increase funding over the FY 2021 
level for: 
•  The delivery of Veterans’ health care associated with exposure to environmental 
hazards  in  the  active  military,  naval,  air,  or  space  service  in  programs 
administered by the Under Secretary for Health; 
•  Any  expenses  incident  to  the  delivery  of  Veterans’  health  care  and  benefits 
associated with exposure to environmental hazards in the active military, naval, 
air,  or  space  service,  including  administrative  expenses,  such  as  information

What Are Appropriated Entitlements?  
While some entitlement programs, such as Medicare and Social Security, are permanently appropriated, some 
programs, such as veterans disability compensation and veteran survivor’s Dependency and Indemnity 
Compensation (DIC) program and pensions, are annually appropriated entitlements known as appropriated 
entitlements. Generally, appropriated entitlements go through the annual appropriations process but are not 
subject to annual appropriations decisions of the congressional appropriations committees. “The Appropriations 
Committees have little or no discretion as to the amounts they provide. .  Even though this funding is included in 
an appropriations bil , it is stil  considered mandatory spending rather than discretionary spending.” For example, 
for veterans’ disability compensation, Congress provides annual funding for tax-free monthly payments to eligible 
veterans with disabilities due to disease or injury incurred or aggravated during military service through annual 
Military Construction, Veterans Affairs, and Related Agencies Appropriations Act. However, the actual funding 
level for disability compensation is determined by the “entitlement” criteria in Chapter 11 of Title 38 of the 
United 
States Code (U.S.C.). The appropriations act appropriates the sums necessary to cover the cost of disability 
compensation payments. Congress, during the appropriations process, does not have the discretion to change the 
amount spent on the disability compensation program.

Expansion of Health Care Eligibility 
Background 
The Veterans Health Administration (VHA) of the Department of Veterans Affairs (VA) provides 
health care, social services, and other supportive services to veterans and family members of 
veterans who meet certain eligibility criteria specified in law and its implementation regulations. 
VHA operates the nation’s largest public integrated direct-health care delivery system34 and pays 
for care provided to veterans under specified criteria.35 In FY2024, of the approximately 18.25 
million veterans living in the United States, an estimated 9.07 million were enrolled in the VA 
health care system, and about 6.31 million were estimated to receive care.36

Honoring our PACT Act of 2022 (P.L. 117-168) 
 
Generally, a veteran has to meet 
three basic criteria to be eligible for VA health care.37 First, the 
veteran must meet the basic eligibility requirement of “veteran status.” That is, a claimant must 
first establish veteran status as a condition of eligibility. For VA benefits purposes, a “veteran” is 
a person who served in the 
active military, naval, air, or space service, and who was discharged 
or released under conditions other than dishonorable.38 Second, the veteran must meet “active 
duty” requirements. Third, the veteran must have served a minimum period of continuous active 
duty. 
The term “active military, naval, air service or space service” includes “(A) 
active duty; (B) 
any 
period of active duty for training during which the individual concerned was disabled or dies 
from a disease or injury incurred or aggravated in line of duty; (C)
 and any period of inactive duty 
for training during which the individual concerned was disabled or dies (i) from injury incurred 
or aggravated in line of duty; or (ii) from an acute myocardial infarction, a cardiac arrest, or a 
cerebrovascular accident occurring during such training.”39 
In addition to establishing their veteran status, individuals who enlisted in the Armed Forces after 
September 7, 1980, as well as those (officer and enlisted) who entered active duty after October 
16, 1981, and had (1) not previously completed at least 24 months of continuous active duty 
service or (2) not previously been discharged or released from active duty under 10 U.S.C. §1171, 
must meet a length-of service requirement. In general, servicemembers must have completed the 
shorter of 24 months of continuous active duty service, or the full period for which they were 
called or ordered to active duty.40 There are certain exemptions to this requirement. Such 
exemptions include, among others, servicemembers (1) discharged for a disability incurred or 
aggravated during active-duty service; (2) discharged for a hardship under 10 U.S.C. §1173 or 
“early out” under 10 U.S.C. §1171; or (3) who served prior to September 7, 1980.41 National 
Guard members and reservists activated under Title 10 of the 
U.S. Code must also complete the 
minimum active duty service requirement.42 For example, a reservist or National Guard member 
federally activated to serve in Iraq or Afghanistan for a period of six months who served the 
entire period would satisfy the active duty service requirement needed to qualify for veteran 
status. 
Once these basic requirements are met, veterans fall into two broad health care eligibility 
categories. The first eligibility category includes veterans with service-connected disabilities;43 
Medal of Honor recipients; Purple Heart recipients; former prisoners of war; veterans exposed to 
toxic substances and environmental hazards, such as Agent Orange; and veterans whose 
attributable income is not greater than an amount established by a “means test.”44 The second 
eligibility category includes veterans who may be eligible to receive care through VA to the extent

line of duty in the active military, naval, air, or space service. VA determines whether veterans have service-connected 
disabilities and, for those with such disabilities, assigns ratings from 0% to 100% based on the severity of the disability. 
Percentages are assigned in increments of 10%. 
44 VA is required to furnish hospital care and medical services to a veteran who is unable to defray the expenses of 
necessary care as stipulated in law and regulations. 38 U.S.C. §1710(a)(2)(G); 38 U.S.C. §1722(a).

resources permit.45 Most eligible veterans are required to formally enroll in VA’s health care 
system to receive services.46 All enrolled veterans are offered a standard medical benefits 
package, which includes (but is not limited to) inpatient and outpatient medical services, 
pharmaceuticals, durable medical equipment, and prosthetic devices.47 In addition, VHA provides 
long-term services and supports, and nursing home care to eligible veterans. 
From time to time Congress has enacted legislation providing special treatment authorities for 
certain groups of veterans. These special treatment authorities include health care for veterans 
potentially exposed to toxic substances or environmental hazards during their military service. 
The next section discusses these special treatment authorities, along with the three new categories 
established by the Honoring our PACT Act of 2022 (P.L. 117-168) and amendments to existing 
authorities made by the act, where applicabl
e. Figure 1 provides a high-level overview of how 
veterans will be eligible for VA health care under the eligibility criteria for toxic exposure or 
deployment to a combat theater. 
Health Care Eligibility for Toxic Exposures48 
Current law provides eight separate criteria under which veterans potentially exposed to toxic 
substances or environmental hazards during their military service may be eligible for VA health 
care. In addition, combat theater veterans have an enhanced period of enrollment eligibility 
during which veterans may receive care for medical conditions possibly related to their service. In 
total, veterans are eligible for VA health care services through nine separate statutory eligibility 
provisions (see
 Figure 1).  
Vietnam-Era, Herbicide-Exposed Veterans49 
In April 1970, Congress held the first of many hearings on the health effects of Agent Orange.50 
Policymakers began to address the health concerns of Vietnam-era veterans in 1981 with the 
passage of the Veterans’ Health Care, Training and Small Business Loan Act (P.L. 97-72). The act 
granted Vietnam-era veterans’ priority status for health care at VA facilities by recognizing a 
veteran’s own report of exposure as sufficient proof to receive medical care, unless there was 
evidence to the contrary. This authority was further amended by the Veterans’ Health Care 
Eligibility Reform Act of 1996 (P.L. 104-262). Under this authority, a veteran does not have to 
demonstrate a link between a certain health condition and exposure to Agent Orange to be eligible 
for medical care; instead, medical care is provided unless the VA determines that the condition 
did not result from exposure to Agent Orange, or unless the condition has been identified by the 
National Academy of Sciences (NAS) as having “limited/suggestive” evidence of 
no association 
between the occurrence of the disease and exposure to a herbicide.51 According to the VA, “[T]he

46 38 U.S.C. §1705; 38 C.F.R. §17.36(a). In some cases, VA provides care to non-enrolled veterans in the following 
classes: veterans who need treatment for a VA-rated service-connected disability, veterans who are VA rated as 50% or 
more service-connected disabled, and veterans who were released from active duty within the previous 12 months for a 
disability incurred or aggravated in the line of duty.

determination of whether a Vietnam-era herbicide-exposed veteran’s disability may be related to 
that exposure is strictly a clinical judgment to be made by the responsible physician (acting in 
accordance with the guidelines issued by the Under Secretary of Health and [conditions identified 
by the National Academy of Sciences].”52 Treatment authority authorized by P.L. 104-262 was 
extended at various intervals by the Veterans Programs Enhancement Act of 1998 (P.L. 105-368) 
and the Department of Veterans Affairs Health Care Programs Enhancement Act of 2001 (P.L. 
107-135), until it was permanently authorized by the Caregivers and Veterans Omnibus Health 
Services Act of 2010 (P.L. 111-163).  
The Honoring our PACT Act of 2022 (P.L. 117-168) amended the definition of Vietnam‐era 
herbicide‐exposed veteran to include the following: 
Veterans who served on active military, naval, air, or space service53 
•  in the Republic of Vietnam during the period beginning on January 9, 1962, and 
ending on May 7, 1975;  
•  in Thailand at any United States or Royal Thai base during the period beginning 
on January 9, 1962, and ending on June 30, 1976, without regard to where on the 
base the veteran was located or what military job specialty the veteran 
performed; 
•  in Laos during the period beginning on December 1, 1965, and ending on 
September 30, 1969; 
•  in Cambodia at Mimot or Krek, Kampong Cham Province during the period 
beginning on April 16, 1969, and ending on April 30, 1969; or 
•  in Guam or American Samoa, or in the territorial waters thereof, during the 
period beginning on January 9, 1962, and ending on July 31, 1980, or served on 
Johnston Atoll or on a ship that called at Johnston Atoll during the period 
beginning on January 1, 1972, and ending on September 30, 1977. 
In addition, a veteran may be considered a Vietnam-era herbicide-exposed veteran if the VA 
Secretary finds the veteran may have been exposed during active service to dioxin during the 
Vietnam-era, regardless of the geographic area of such service, or was exposed during such 
service to a toxic substance found in an herbicide or defoliant used for military purposes during 
such era, regardless of the geographic area of such service.54 
Veterans who have served active military, naval, air, or space service as specified above during 
the Vietnam-era are eligible for hospital care, medical services, and nursing home care even if 
there is insufficient medical evidence to conclude that such disability may be associated with 
herbicide exposure. Such veterans are deemed ineligible in cases where VA determines that the 
condition did not result from exposure to Agent Orange, or in cases where the condition has been 
identified by NAS as having “limited/suggestive” evidence of no association between the 
occurrence of the disease and exposure to a herbicide.55 Veterans are exempt from copayment and 
 
exposure that human beings are known to encounter, are consistent in not showing a positive association between any 
magnitude of exposure to herbicides and the outcome of disease.

Under the provisions in the Honoring our PACT Act of 2022 (P.L. 117-168), Vietnam-era veterans 
who served in the above-mentioned time periods and locations are eligible to enroll in the VA 
health care system beginning October 1, 2022.57  
Radiation-Exposed Veterans58 
The Veterans’ Health Care, Training and Small Business Loan Act of 1981 (P.L. 97-72) 
established eligibility for VA medical care for veterans whose conditions may have resulted from 
radiation exposure on the same basis as eligibility as that provided for Vietnam-era, herbicide-
exposed veterans. The Veterans’ Health Care Eligibility Reform Act of 1996 (P.L. 104-262) made 
permanent this authority for veterans exposed to radiation. Under this authority, veterans who 
served on active duty and participated in a radiation-risk activity (see definition below),59 as well 
as individuals who, while a member of a reserve component of the Armed Forces, participated in 
a radiation-risk activity during a period of active duty for training or inactive-duty training, are 
eligible for hospital care, medical services, and nursing home care for any presumptive disease 
listed at 38 U.S.C. §1112(c)(2),60 or for any other disease for which that there is credible evidence 
showing a positive association between the disease in humans and exposure to ionizing radiation, 
as determined by the Secretary.61 Veterans are exempt from copayment and third-party billing for 
hospital care, medical services, nursing home care, and medications prescribed on an outpatient 
basis for any condition possibly associated with radiation exposure.62  
The Honoring our PACT Act of 2022 (P.L. 117-168) amended the definition of “radiation-risk 
activity” to include veterans who took part in the cleanup of Enewetak Atoll from January 1, 
1977, through December 31, 1980; veterans who served in the cleanup of the collision of a U.S. 
Air Force B-52 bomber over Palomares, Spain, from January 17, 1966, through March 31, 1967; 
and veterans involved in the cleanup and decontamination effort of a B-52 bomber crash in Thule, 
Greenland, from January 21, 1968, to September 25, 1968.63

participated in the cleanup efforts on Enewetak Atoll beginning in 1977. This cleanup effort was referred to as the 
Enewetak Radiological Support Project. On January 17, 1966, a U.S. Air Force B-52 bomber collided with its refueling 
tanker, and four thermonuclear bombs fell near Palomares, Spain. Two of the bombs detonated and dispersed 
plutonium. In another incident, on January 21, 1968, a fire on a U.S. Air Force B-52 bomber flying over Greenland

Persian Gulf War Veterans66 
As it did for Vietnam-era veterans exposed to Agent Orange, Congress passed, in 1993, P.L. 103-
210, which provides additional authority for VA to provide health care for veterans of the Persian 
Gulf War.67 For these veterans, health care is provided for medical conditions possibly related to 
exposure to toxic substances or environmental hazards during active duty service in the 
Southwest Asia theater of operations during the Persian Gulf War.68 Veterans who served on 
active duty between August 2, 1990, and November 11, 1998, in the Southwest Asia theater of 
operations during the Persian Gulf War are eligible for hospital care, medical services, and 
 
detonation.” (Sources:

Combat-Theater Veterans70 
In 1998, Congress—responding to growing concern over Persian Gulf War veterans’ undiagnosed 
illnesses—passed the Veterans Programs Enhancement Act of 1998 (P.L. 105-368). The act 
entitled veterans (including National Guard and reserve components) who served on active duty 
in a theater of combat operations during a period of war71 after the Persian Gulf War to enroll in 
VA health care during a two-year period following the date of discharge and to receive care, even 
if medical evidence is insufficient to conclude that such illnesses are attributable to such service. 
In 2007, the National Defense Authorization Act (NDAA; P.L. 110-181), FY2008, created a five-
year period of enrollment eligibility for veterans who served in a theater of combat operations 
after November 11, 1998.72 The Clay Hunt Suicide Prevention for American Veterans Act (P.L. 
114-2) authorized an additional one-year enrollment eligibility period for veterans who were 
discharged from active duty after January 1, 2009, and before January 1, 2011, but who did not 
enroll during the five-year period of post-discharge eligibility. This one-year period began on 
February 12, 2015, the enactment date of the Clay Hunt Suicide Prevention for American 
Veterans Act. It ended on February 12, 2016.73 
The Honoring our PACT Act of 2022 (P.L. 117-168) amended the five-year period and extended it 
to 10 years. In addition, the act further broadened the types of veterans who could qualify based 
on service in the Persian Gulf War. Veterans who served between September 11, 2001, and 
October 1, 2013, and were unable to enroll during the five-year period of post-discharge 
eligibility (i.e., before October 1, 2022), received an additional one-year period of enrollment 
eligibility starting October 1, 2022 (i.e., until September 30, 2023).74 Furthermore, the act 
clarifies that service in the Persian Gulf War applies to any veteran who, during such period of 
service, received the Armed Forces Expeditionary Medal, Service Specific Expeditionary Medal, 
Combat Era Specific Expeditionary Medal, Campaign Specific Medal, or any other combat

In general, returning combat veterans are assigned to Priority Category 6, unless they are eligible 
for placement in a higher enrollment priority category based on other eligibility criteria.76 These 
veterans are eligible for hospital care, medical services, and nursing home care for any illness, 
unless medical evidence is insufficient to conclude that such disability may be associated with 
service in the Persian Gulf War. Veterans are not charged copays for medication or treatment of 
conditions potentially related to their combat service.77 At the end of the 10-year period, veterans 
enrolled in Priority Category 6 may be reenrolled in Priority Category 7 or 8, or a higher 
enrollment priority category, depending on their service-connected disability status and income 
level. Some may be required to make copayments for nonservice-connected conditions based on 
copay requirements for Priority Category 7 and 8.78 The above criteria also apply to National 
Guard and reserve personnel who were called to active duty by federal executive order and who 
served in a theater of combat operations after November 11, 1998. The most recent discharge date 
is used for servicemembers who have been called to duty multiple times.  
Veterans Who Participated in Operation Shipboard Hazard and Defense 
(SHAD)/Project 112 Tests79 
Between 1962 and 1973, the Department of Defense (DOD) planned and conducted chemical and 
biological warfare tests at the Deseret Test Center in Fort Douglas, UT. The testing program, 
known as Project 112, included shipboard and land-based testing. Project Shipboard and Hazard 
Defense (SHAD) was the shipboard part of these tests.80 According to DOD, “SHAD was 
designed to test ships’ vulnerability to biological or chemical attack.”81 In response to health 
concerns of veterans who were involved in Deseret Test Center tests, Congress passed the 
Veterans Health Care, Capital Asset, and Business Improvement Act of 2003 (P.L. 108-170), 
which authorized hospital care, medical services, and nursing home care for any illness, without a 
requirement for service-connection.  
Veterans are exempt from copayment and third-party billing for hospital care, medical services, 
nursing home care, and medications prescribed on an outpatient basis for any condition possibly 
associated with these chemical and biological tests.82

Camp Lejeune Veterans83 
In response to potential health effects of contaminated water at the Marine base at Camp Lejeune, 
NC, Congress passed the Honoring America’s Veterans and Caring for Camp Lejeune Families 
Act of 2012 (P.L. 112-154), as amended by the Consolidated and Further Continuing 
Appropriations Act, 2015 (P.L. 113-235, Division I, Title II, Section 243).84 This act established a 
presumptive service-connection for veterans’ health care for one or more of 15 diseases and 
health conditions that may be associated with exposure to trichloroethylene (TCE), 
tetrachloroethylene (PCE), vinyl chloride, and other contaminants discovered in drinking water 
supplies at Camp Lejeune. Veterans and their family members who worked or lived at Camp 
Lejeune for no less than 30 days (consecutive or nonconsecutive) from August 1, 1953, to 
December 31, 1987, generally are eligible for VA health care services under this law. Eligible 
veterans and family members can receive free care for any of the 15 covered illnesses or 
conditions.85 To be eligible, a veteran or former reservist or member of the National Guard (1) 
must have been stationed at Camp Lejeune, or traveled to Camp Lejeune as part of his or her 
professional duties, and (2) must have served on active duty for at least 30 days (consecutive or 
nonconsecutive) during the period beginning on August 1, 1953, and ending on December 31, 
1987.

Veterans Who Participated in a Toxic Exposure Risk Activity (TERA)86 
The Honoring our PACT Act of 2022 (P.L. 117-168) amends current law and authorizes hospital 
care (including mental health services and counseling), medical services, and nursing home care 
to veterans who participated in a “toxic exposure risk activity”87 while serving on active duty, 
active duty for training, or inactive duty training. In these cases, health care is authorized for any 
illness, unless medical evidence is insufficient to conclude that the condition is attributable to 
such service. The term toxic exposure risk activity means a record in an exposure tracking system 
indicating that the veteran carried out the activity; or where the VA determines that it is 
“reasonably prudent” to provide care and services to a veteran to protect the health of such 
veteran. The tracking system means a system, program, or pilot program used by VA or DOD to 
track how veterans or members of the Armed Forces have been exposed to various occupational 
or environmental hazards; and also includes the Individual Longitudinal Exposure Record 
(ILER), or successor system (se
e Figure 2).88  
Veterans are exempt from copayment and third-party billing for hospital care, medical services, 
nursing home care, and medications prescribed on an outpatient basis for any condition possibly 
associated with a toxic exposure risk activity. 
Under the Honoring our PACT Act of 2022, the Secretary is required to implement the phase-in 
enrollment of veterans who participated in a toxic exposure risk activity as follows:89  
•  October 1, 2024, for veterans who were discharged or released from the active 
military, naval, air, or space service during the period beginning on August 2, 
1990, and ending on September 11, 2001;  
•  October 1, 2026, for veterans who were discharged or released from the active 
military, naval, air, or space service during the period beginning on September 
12, 2001, and ending on December 31, 2006;  
•  October 1, 2028, for veterans who were discharged or released from the active 
military, naval, air, or space service during the period beginning on January 1, 
2007, and ending on December 31, 2012; and  
•  October 1, 2030, for veterans who were discharged or released from the active 
military, naval, air, or space service during the period beginning on January 1, 
2013, and ending on December 31, 2018. 
The Secretary may revise these phase-in dates based on the number of veterans seeking care and 
the available resources. When modifying the dates, the Secretary must notify the Senate and 
House Committees on Veterans’ Affairs of the proposed modification and publish a notice with 
the modified date in the 
Federal Register (see section on 
“Elimination of the Phase-In Dates for

nursing home care for any illness, unless medical evidence is insufficient to conclude that the 
condition is attributable to such service. The provision of this care is authorized for any veteran 
based on active duty in specific locations, which are broken out into two categories (see
 Figure 
2).  
Under the first category, eligibility would be granted to any veteran who on or after August 2, 
1990, performed active military, naval, air, or space service while assigned to a duty station in the 
following locations (including the air space above): Bahrain, Iraq, Kuwait, Oman, Qatar, Saudi 
Arabia, Somalia, or the United Arab Emirates.  
Under the second category, eligibility would be granted to any veteran who on or after September 
11, 2001, performed active military, naval, air, or space service while assigned to a duty station 
(including the air space above) in the following locations: Afghanistan, Djibouti, Egypt, Jordan, 
Lebanon, Syria, Yemen, Uzbekistan, the Philippines, or any other country determined relevant by 
the Secretary.  
Veterans are exempt from copayment and third-party billing for hospital care, medical services, 
nursing home care, and medications prescribed on an outpatient basis for any condition possibly 
associated with service in these locations. 
Under the Honoring our PACT Act of 2022, the Secretary is required to implement the phase-in 
enrollment of veterans who were stationed at a specific duty station location as follows:91  
•  October 1, 2024, for veterans who were discharged or released from the active 
military, naval, air, or space service during the period beginning on August 2, 
1990, and ending on September 11, 2001;  
•  October 1, 2026, for veterans who were discharged or released from the active 
military, naval, air, or space service during the period beginning on September 
12, 2001, and ending on December 31, 2006;  
•  October 1, 2028, for veterans who were discharged or released from the active 
military, naval, air, or space service during the period beginning on January 1, 
2007, and ending on December 31, 2012; and  
•  October 1, 2030, for veterans who were discharged or released from the active 
military, naval, air, or space service during the period beginning on January 1, 
2013, and ending on December 31, 2018. 
The Secretary may revise these phase-in dates based on the number of veterans seeking care and 
the available resources. When modifying the dates, the Secretary must notify the Senate and

Elimination of the Phase-In Dates for New Cohorts of Toxic 
Exposed Veterans 
As authorized by Section 103 of the Honoring our PACT Act of 2022, for the Secretary to revise 
the phase-in dates, on February 26, 2024, VA announced that it intends to eliminate the phase-in 
dates established by the Honoring our PACT Act of 2022, and would begin accepting applications 
for enrollment in the VA health care system of all eligible veterans.94 On March 5, 2024, VA 
published a notice and provided sub-regulatory guidance in the 
Federal Register95
 that beginning 
March 5, 2024, VA would process applications for enrollment in the VA health care system of 
veterans who participated in a Toxic Exposure Risk Activity (TERA),96 who served in a specific 
duty station during specific periods of time,97 or who were deployed in support of specific 
contingency operations (see
 Figure 3).98  
According to VA’s sub-regulatory guidance, to be eligible under the TERA category, veterans 
during active duty, active duty for training, or inactive duty training should have been exposed to 
one or more of the following: 
air  pollutants  (burn  pits,  sand,  dust,  particulates,  oil  well  fires,  sulfur  fires),  chemicals 
(pesticides, herbicides, depleted uranium with embedded shrapnel, contaminated water), 
occupational hazards (asbestos, industrial solvents, lead, paints including chemical agent 
resistant  coating,  firefighting foams),  radiation  (nuclear  weapons  handling,  maintenance 
and  detonation,  radioactive  material,  calibration  and  measurement  sources,  X-rays, 
radiation from military occupational exposure), and warfare agents (nerve agents, chemical 
and biological weapons).99  
This could be determined by an entry in the Individual Longitudinal Exposure Record (ILER) or 
if the Veterans Benefits Administration (VBA) has previously determined that the veteran 
participated in a TERA based on a disability compensation determination.100 Additionally, 
veterans could identify any potential TERA when applying for health care enrollment, and VA 
would make a determination of their eligibility based on records in Veterans Benefits 
Management System (VBMS) TERA Memorandum Tool maintained by VBA, Veterans 
Information Solution (VIS), among other sources.101 Moreover, if veterans submit evidence of

Toxic Exposure Screenings of Veterans 
Section 603 of the Honoring our PACT Act of 2022 (P.L. 117-168) mandated that VHA 
implement toxic exposure screenings to identify veterans enrolled in the VA health care system 
with potential toxic exposures during military, naval, air, or space service as part of their health 
care screenings. The act mandated that the department implement this requirement by November 
8, 2022.107 The law also required that enrolled veterans must be screened at least once every 
five years. The Secretary is required to consider updating the screening tool at least biennially to 
ensure that it contains the most current information. According to VA, “Veterans who are not 
enrolled and who meet eligibility requirements will have an opportunity to enroll and receive the 
screening,”108 and information gathered during the toxic exposure screening will be included in 
 
107 Department of Veterans Affairs, “Tomorrow, all Veterans enrolled in VA health care will be eligible for new toxic 
exposure screenings,” press release, November 7, 2022, https://www.va.gov/opa/pressrel/pressrelease.cfm?id=5838.

veterans’ electronic health records and be used to connect them with applicable VA benefits and 
services.109  
Prior to implementing the screening tool across VA medical centers and clinics nationwide, VHA 
piloted the toxic exposure screening tool at 13 medical facilities. Based on feedback from the 
pilot sites, VHA revised the screening tool before deploying it to all VA health care facilities. 
During the initial phases, the toxic exposure screening will be administered either during or 
outside of primary care appointments. When conducted during a primary care appointment, the 
screening would be conducted by a licensed practical nurse (LPN) on the veteran’s care team110 or 
by the primary care provider. When conducted outside of the primary care appointment, the 
screening would be conducted by the appropriate non-primary care staff member. For veterans 
who are not assigned to a primary care team, or who wish to be screened sooner, the screening 
would be completed by a Toxic Exposure Screening (TES) Navigator.111  
The screening tool is included in VHA’s Computerized Patient Record System (CPRS) and 
appears as a clinical reminder to VHA providers (see example of first screen i
n Figure 4).

110 Generally, veterans enrolled in the VA health care system are assigned to a primary care team known as a Patient 
Aligned Care Team (PACT). The team is composed of a primary care provider (doctor, nurse practitioner, or 
physician’s assistant), clinical pharmacist, registered nurse (RN), and licensed practical nurse (LPN) or medical 
assistant. See https://www.patientcare.va.gov/primarycare/pact/Resources.asp.

Notes: This is a screenshot of the Toxic Exposure Screening clinical reminder window that appears in 
Computerized Patient Record System (CPRS). Based on a veteran’s exposure concern, several additional screens 
are triggered to be completed by the provider/Exposure Screening (TES) navigator. 
The screening would include three questions, as outlined in the text box below:

As shown i
n Figure 5, if a veteran responds “YES” to potential exposure questions, all “YES” 
responses will be forwarded to the veteran’s primary care provider for follow up within 14 days. 
If the veteran has not been assigned to a primary care team, the Toxic Exposure Screening 
Navigators would follow-up by providing additional assistance, such as assigning the veteran to a 
primary care team (with the veteran’s consent) and referring the veteran to additional information, 
such as exposure-related benefits. 
If the screening is performed by a veteran’s primary care provider, and the veteran indicates a 
concern pertaining to the toxic exposure, a suspected toxic exposure diagnosis code would be 
added to the problem list in the CPRS for future reference, and appropriate clinical assessments 
will be conducted and documented. Veterans would also be provided with information on 
exposure-related benefits, such as information on presumptive service-connected conditions 
related to toxic exposures and health care registries.112 
If a veteran responds “NO” to potential exposure questions, the veteran would be given a handout 
with relevant information and told to follow up with their health care team if any health concerns 
occur before the next toxic exposure screening in five years.113 
Veterans who respond “I Don’t Know” to the environmental exposure questions would be asked 
if they have any other health care concerns, which would also be documented; however, the toxic 
exposure diagnosis code would not be added to the CPRS, and those veterans would be screened 
 
112 VA maintains several health registries that provide special health examinations and health-related information to 
veterans who may have been potentially exposed to environmental hazards during service. The registries include the 
Airborne Hazards and Open Burn Pit Registry; the Gulf War Registry; the Depleted Uranium Follow-Up Program; the 
Toxic Embedded Fragment Surveillance Center; the Agent Orange Registry; and the Ionizing Radiation Registry. 
Certain veterans can participate in a VA health registry and receive free medical examinations, including laboratory 
and other diagnostic tests deemed necessary by an examining clinician. See https://www.publichealth.va.gov/
exposures/publications/military-exposures/meyh-4/registry.asp. Additional resources for veterans can be found at
