Private Health Insurance Market Reforms in the Affordable Care Act (ACA)

Summary
The Affordable Care Act (ACA, P.L. 111-148, as amended) establishes federal requirements that
apply to private health insurance. The market reforms affect insurance offered to groups and
individuals and impose requirements on sponsors of coverage (e.g., employers). In general, all of
ACA’s market reforms are currently effective; some became effective shortly after ACA was
passed in 2010, while others are effective for plan years that begin on or after January 1, 2014.
While some of the market reforms had previously been enacted in some states, many of the
reforms are new at the federal level. Collectively, the reforms create federal minimum
requirements with respect to access to coverage, premiums, benefits, cost-sharing, and consumer
protections. For example, the requirement to offer health plans on a guaranteed issue basis means
that, in general, insurers must accept every applicant for health coverage, as long as the applicant
agrees to the terms and conditions of the coverage (e.g., premium). The requirement to offer the
essential health benefits means that certain plans have to cover a specified package of benefits.
The applicability of the market reforms across types of plans is not uniform. Some of the reforms
apply to all three segments of the private insurance market—nongroup, small group, and large
group—while others may apply only to plans offered in the nongroup and small group markets. In
the group market, the reforms do not always apply to both fully insured plans (plans offered by
state-licensed carriers that are purchased by employers or other sponsors) and self-insured entities
(groups that set aside funds to pay for health benefits directly). The applicability of the reforms
also depends on whether a plan has “grandfathered” status. Under ACA, an existing health plan in
which a person was enrolled on the date of ACA enactment was grandfathered; the plan can
maintain its grandfathered status as long as it meets certain requirements. Grandfathered health
plans are exempt from the majority of ACA market reforms.
While the applicability of the market reforms is not necessarily uniform across plan types, it is
uniform for plans offered inside and outside health insurance exchanges. Every state has an
exchange, and individuals and small employers can use the exchanges to shop for and obtain
health insurance coverage. The same market reforms apply to a nongroup plan offered through an
exchange and a nongroup plan offered in the market outside of an exchange. Some types of plans
do not have to comply with any of the market reforms. For example, retiree-only health plans are
not required to comply with federal health insurance requirements, including ACA’s market
reforms.
This report provides background information about the private health insurance market, including
market segments and regulation. It then describes each ACA market reform. The reforms are
grouped under the following categories: obtaining coverage; keeping coverage; cost of
purchasing coverage; covered services; cost-sharing limits; consumer assistance and other health
care protections; and plan requirements related to health care providers. The Appendix of the
report provides details about the types of plans that are required to comply with the different
reforms.

Private Health Insurance Market Reforms in the Affordable Care Act (ACA)

he Affordable Care Act (ACA, P.L. 111-148, as amended) includes reforms of the health
insurance market that impose requirements on private health insurance plans.1 Such
Treforms relate to the offer, issuance, generosity, and pricing of health plans, among other
requirements. Certain reforms also require the participation of public agencies and officials, such
as the Secretary of Health and Human Services (HHS), in order to facilitate administrative or
operational elements of the insurance market.
This report first provides background information about the private health insurance market and
then describes the market reforms included in ACA. The Appendix of the report provides
additional information about how ACA market reforms apply to different market segments and
types of health plans.
Background
Health Insurance Markets
The private health insurance market is often characterized as having three segments—the large
group, small group, and individual markets. Insurance sold in the large and small group markets
refers to plans offered through a plan sponsor, typically an employer.2 Prior to ACA, large group
plans typically had more than 50 workers, and small group plans had 50 or fewer workers.
However, ACA implements specific definitions of large and small groups that affect the
provisions discussed in this report. Prior to 2016, states can elect to define “small employers” as
those that employ 100 or fewer employees or those that employ 50 or fewer. Beginning in 2016,
small employers will be defined as those with 100 or fewer workers. The nongroup, or individual,
market refers to insurance policies offered to individuals and families buying insurance on their
own (i.e., not through a plan sponsor).
State and Federal Regulation
States are the primary regulators of the business of health insurance, as codified by the 1945
McCarran-Ferguson Act (15 U.S.C. §§1011 et seq.). Each state has a large, unique set of rules
that apply to state-licensed insurance carriers and the plans they offer.3 Such rules are broad in
scope and address a variety of issues, such as the legal structure and organization of insurance
issuers (e.g., licensing requirements), business practices (e.g., marketing rules), market conduct
(e.g., capital and reserve standards), nature of insurance products (e.g., benefit mandates), and
consumer protections (e.g., plan disclosure requirements), among others.

1 For simplicity’s sake, the term “plan” is used generically in this report. It applies to different types of health coverage
provided to groups (e.g., employees of a single firm) and individuals.
2 The reference to group markets technically applies to health plans offered by state-licensed insurance carriers and
purchased by employers and other plan sponsors. However, health insurance coverage provided through a group may
also be sponsored through “self-insurance.” Groups that self-insure set aside funds to pay for health benefits directly,
and those groups bear the risk for covering medical expenses generated by the individuals covered under the self-
insured plan.
3 State regulation of health insurance applies only to state-licensed entities. Since self-insured plans are financed
directly by the plan sponsor, such plans are not subject to state law.

Private Health Insurance Market Reforms in the Affordable Care Act (ACA)

In addition to the state regulation of insurance, the federal government has established federal
standards applicable to health coverage and imposes requirements on state-licensed insurance
carriers and sponsors of health benefits (e.g., employers). The federal regulation of health
coverage is particularly salient with respect to health benefits provided through employment.4
ACA follows the model of federalism that has been employed in prior federal health insurance
reform efforts (e.g., Health Insurance Portability and Accountability Act of 1996). In other words,
while ACA establishes many federal rules, the states have primary responsibility for monitoring
compliance with and enforcement of such rules. In addition, states may impose additional
requirements on insurance carriers and the health plans they offer, provided that the state
requirements neither conflict with federal law nor prevent the implementation of federal market
reforms.

7 The reforms that go into effect in 2014 are generally effective for plan or policy years that begin on or after January 1,
2014. In other words, when a plan or policy is renewed in 2014 it must become compliant with all ACA market reforms
that are effective in 2014 (but it does not necessarily have to comply with the reforms on January 1, 2014).

and whether the plan has grandfathered status.8 However, the reforms do not apply to certain
types of plans (this is true of other federal health reforms as well). For example, retiree-only
health plans are not required to comply with federal health insurance requirements, including
ACA’s market reforms.9 In the text of this report the term “plan” is used generally; for
information as to the specific types of plans (i.e., a grandfathered plan in the large group market)
to which a reform applies, see the Appendix.
In this report, the reforms are grouped under the following categories: obtaining coverage;
keeping coverage; cost of purchasing coverage; covered services; cost-sharing limits; consumer
assistance and other health care protections; and plan requirements related to health care
providers.
Obtaining Coverage
Guaranteed Issue
ACA requires certain types of coverage to be offered on a guaranteed issue basis.10 In general,
“guaranteed issue” in health insurance is the requirement that a plan accept every applicant for
health coverage, as long as the applicant agrees to the terms and conditions of the insurance offer
(such as the premium). Nongroup plans that must be offered on a guaranteed issue basis are
allowed to restrict enrollment to open and special enrollment periods.11 With regard to plans
offered in the group market, in general “guaranteed issue” means that a plan sponsor (e.g., an
employer) must be able to purchase a group health plan any time during a year.12
Regulations allow plans that would otherwise be required to offer coverage on a guaranteed issue
basis to deny coverage to individuals and employers in certain circumstances.13 Those
circumstances include when a plan demonstrates that it does not have the network capacity to
deliver services to additional enrollees and when the plan demonstrates that it does not have the
financial capacity to offer additional coverage.

8 A grandfathered health plan refers to an existing plan in which at least one individual has been enrolled since
enactment of ACA (March 23, 2010). To maintain grandfathered status, a plan must avoid certain changes to employer
contributions, access to coverage, benefits, and cost-sharing (e.g., any increase in co-insurance requirement). For more
information about grandfathered status, see CRS Report R41166, Grandfathered Health Plans Under the Patient
Protection and Affordable Care Act (ACA)
, by Bernadette Fernandez.
9 The federal exemption for retiree-only health plans is not a new exemption. Retiree-only health plans have been
exempt from federal health insurance requirements since enactment of the Health Insurance Portability and
Accountability Act of 1996. For additional information about these issues, see the Appendix in CRS Report R41166,
Grandfathered Health Plans Under the Patient Protection and Affordable Care Act (ACA), by Bernadette Fernandez.
10 42 U.S.C. §300gg-1.
11 The annual open enrollment periods in the nongroup market are the same inside and outside ACA health insurance
exchanges. For policy years beginning on or after January 1, 2014, the open enrollment period is October 1, 2013,
through March 31, 2014. The qualifying events for special enrollment periods are defined in §603 of the Employee
Retirement Income Security Act (ERISA, P.L. 93-406) and in 45 C.F.R. §155.420(d).
12 Regulations provide an exception for plans offered in the small group market. The plans may limit enrollment to an
annual period from November 15 through December 15 of each year if the plan sponsor does not comply with
provisions relating to employer contribution or group participation rules, pursuant to state law.
13 45 C.F.R. §147.104(c) and (d).

Private Health Insurance Market Reforms in the Affordable Care Act (ACA)

Nondiscrimination Based on Health Status
ACA prohibits plans from basing eligibility or coverage on health status-related factors.14 Such
factors include health status, medical condition (including both physical and mental illness),
claims experience, receipt of health care, medical history, genetic information, evidence of
insurability (including conditions arising out of acts of domestic violence), disability, and any
other health status-related factor determined appropriate by the Secretary of HHS. ACA allows,
however, for the offering of premium discounts or rewards based on enrollee participation in
wellness programs, in keeping with prior federal law.15
Extension of Dependent Coverage
ACA requires that if a plan offers dependent coverage, the plan must make such coverage
available to a child under age 26.16 Plans that offer dependent coverage must make coverage
available for both married and unmarried adult children under age 26, but not for the adult child’s
children or spouse (although a plan may voluntarily choose to cover them).
Prohibition of Discrimination Based on Salary
The sponsors of health plans (e.g., employers) are prohibited from establishing eligibility criteria,
for any full-time employee, that are based on the total hourly or annual salary of the employee.17
Eligibility rules cannot be permitted to discriminate in favor of higher-wage employees. The
Departments (HHS, Labor, and Treasury) have determined that compliance with this requirement
is not required until after regulations are issued; as of the date of this report, regulations have not
been issued.18
Waiting Period Limitation
ACA prohibits plans from establishing waiting periods greater than 90 days.19 A “waiting period”
refers to the time period that must pass before coverage for an individual who is eligible to enroll
under the terms of the plan can become effective. In general, if an individual can elect coverage
that becomes effective within 90 days, the coverage complies with this provision.

14 42 U.S.C. §300gg-4.
15 The Health Insurance Portability and Accountability Act of 1996 (HIPAA) allows group plans to establish premium
discounts or rebates or modify cost-sharing requirements in return for adherence to a wellness program. If a reward is
provided based solely on participation in a wellness program, or if it does not provide a reward, the program complies
with HIPAA without having to satisfy any additional standards, as long as the program is made available to all
similarly situated individuals. If a reward is based on an individual meeting a certain standard relating to a health
factor, then the program must meet additional requirements specified in HIPAA regulations. Under ACA, the reward
must be capped at 30% of the cost of the employee-only coverage under the plan, but the Secretaries of HHS, Labor,
and the Treasury would have the discretion to increase the reward up to 50% of the cost of coverage if the increase is
determined to be appropriate.

Keeping Coverage
Guaranteed Renewability
“Guaranteed renewability” in health insurance is the requirement on a plan to renew individual
coverage at the option of the policyholder, or renew group coverage at the option of the plan
sponsor. Under ACA, most plans offered in the nongroup and small group markets must renew
coverage at the option of the enrollee or plan sponsor; however, plans may discontinue coverage
under certain circumstances.20 For example, a plan may discontinue coverage if the individual or
plan sponsor fails to pay premiums or if an individual or plan sponsor performs an act that
constitutes fraud in connection with the coverage.21
Prohibition on Rescissions
The practice of “rescission” refers to the retroactive cancellation of medical coverage after an
enrollee has become sick or injured. ACA generally prohibits rescissions, except that rescissions
will still be permitted in cases where the covered individual committed fraud or made an
intentional misrepresentation of material fact as prohibited by the terms of the plan.22 A
cancellation of coverage in this case requires that a plan provide at least 30 calendar days
advanced notice to the enrollee.23
Costs Associated with Coverage
Rating Restrictions
ACA imposes adjusted (or modified) community rating rules on the determination of premiums.24
“Adjusted community rating” rules prohibit plans from pricing health insurance products based
on health factors but allow it for other key characteristics such as age. ACA’s rating rules restrict
premium variation to the four factors described below.
Self-only or family enrollment. In most states, plans can vary premiums based on whether an
individual or an individual and any number of his/her dependents enroll in the plan. However, if a
state does not permit rating variation for age and tobacco, the state is allowed to require that
premiums for family coverage are determined by using state-established uniform family tiers.25
For example, such a state may allow plans to vary premiums based on self-only coverage, self
plus one coverage, and family coverage.

20 42 U.S.C. §300gg-4.
21 45 C.F.R. §147.106.
22 42 U.S.C. §300gg-12.
23 45 C.F.R. §147.128.
24 42 U.S.C. §300gg.
25 As of the date of this report only two states, New York and Vermont, prohibit plans from using tobacco and age to
vary rates. Both states allow plans to vary premiums using state-established uniform family tiers.
Congressional Research Service

Private Health Insurance Market Reforms in the Affordable Care Act (ACA)

Geographic rating area. States are allowed to establish one or more geographic rating areas
within the state for the purposes of this provision. The rating areas must be based on one of the
following geographic boundaries: (1) counties; (2) three-digit zip codes;26 or (3) metropolitan
statistical areas (MSAs) and non-MSAs.27 If a state does not establish rating areas or if the
Centers for Medicare and Medicaid Services (CMS) determines that a state’s proposed rating
areas are inadequate,28 then the default is one rating area for each MSA in the state and one rating
area comprising all non-MSAs in the state.
Tobacco use. Plans are allowed to charge a tobacco user up to 1.5 times the premium that the
plan will charge an individual who does not use tobacco.
Age. Plans can vary premiums by no more than a 3 to 1 ratio for adults aged 21 and older. This
means that a plan will not be allowed to charge an older individual more than three times the
premium that the plan will charge a 21-year-old. Regulations require that each state use a uniform
age rating curve to specify the rates across all adult age bands, and they require each state to set a
separate rate for all individuals aged 20 and younger. HHS created an age curve that states may
choose to use, but some states have implemented standards other than the federal defaults.29
Figure 1 shows the federally established age rating curve. In states that choose to use this curve,
a plan cannot set a premium for a child (age 0-20) that is more than 63.5% of a premium for a 21-
year-old, and a premium for an individual age 64 and older cannot be more than three times that
of a premium for a 21-year-old.

26 A three-digit zip code refers to the first three digits of a five-digit zip code. A three-digit zip code represents a larger
geographical area than a five-digit zip code, as all five-digit zip codes that share the same first three numbers are
included in the three-digit zip code.
27 OMB establishes delineations for various statistical areas, including MSAs. The most recent delineations are
available at http://www.whitehouse.gov/sites/default/files/omb/bulletins/2013/b-13-01.pdf.
28 A state’s rating areas will be presumed adequate if either of the following conditions are met: the state established the
rating areas for the entire state prior to January 1, 2013, or the state establishes the rating areas after January 1, 2013,
for the entire states and there are no more rating areas than the number of MSAs in the state plus one. A state that
establishes its rating periods after January 1, 2013, may propose a greater number of rating areas to CMS, provided
such rating areas are based on the geographic boundaries noted above.
29 For information about states that have established their own age curves, see http://www.cms.gov/CCIIO/Programs-
and-Initiatives/Health-Insurance-Market-Reforms/state-rating.html.

Notes: In implementing the ACA’s rating restriction requirements, states may use a different uniform age curve,
provided it prohibits plans from varying premiums based on age by more than a 3 to 1 ratio.
Rate Review
The intent of the rate review program is to ensure that all proposed health insurance rate increases
in the small group and individual markets that meet or exceed a specified threshold are reviewed
by a state or CMS to determine whether they are unreasonable.30 Plans subject to review are
required to submit to the HHS and the relevant state a justification for the proposed rate increase
prior to implementation of the premium, and HHS will publicly disclose the information.31
For the first year of the rate review program (plan years beginning on or after September 1, 2011),
a proposed rate increase was considered unreasonable if the increase was 10% or more (over a
12-month period beginning on September 1). Since then, states have had the option to establish
state-specific thresholds; the 10% threshold remains in effect in any states that do not establish
state-specific thresholds.32 Note that ACA’s rate review process does not establish federal
authority to deny implementation of a proposed rate increase. (This is a “sunshine” provision
designed to publicly expose rate increases determined to be unreasonable.)

30 ACA does not apply the rate review requirements to grandfathered health plans.

Private Health Insurance Market Reforms in the Affordable Care Act (ACA)

Single Risk Pool
A health insurance issuer must consider all enrollees in plans offered by the issuer to be members
of a single risk pool.33 More specifically, an issuer must consider all enrollees in nongroup plans
offered by the issuer to be members of a single risk pool; the issuer must have a separate risk pool
for all enrollees in small group plans offered by the issuer. (However, ACA gives states the option
to merge its nongroup and small group markets; if a state does so, an issuer will have a single risk
pool for all enrollees in its nongroup and small group plans.)
A risk pool is used to develop rates for coverage. A result of the single risk pool requirement is
that issuers must consider the medical claims experience of enrollees in all plans (nongroup and
small group separately, or combined) offered by the issuer when developing rates.
Covered Services
Coverage of Essential Health Benefits
ACA requires plans to cover the essential health benefits (EHB).34 ACA does not explicitly list
the benefits that comprise EHBs; rather, it lists 10 broad categories from which benefits and
services must be included.35 ACA requires the Secretary to further define the EHB. In response,
the Secretary outlined a process for defining the EHB for at least 2014 and 2015; the Secretary
may revisit how the EHB are defined for the 2016 plan year and beyond.
For 2014 and 2015, the Secretary asked each state to select a benchmark plan from four different
types of plans.
• the largest plan by enrollment in any of the three largest small group insurance
products in the state’s small group market;
• any of the largest three state employee health benefit plans by enrollment;
• any of the largest three national Federal Employees Health Benefit (FEHBP) plan
options by enrollment; or
• the largest insured commercial non-Medicaid Health Maintenance Organization
(HMO) operating in the state.
If the selected benchmark plan did not cover services and benefits from all 10 categories listed in
statute, a state is required to supplement the benchmark plan (according to a process outlined by
HHS) to ensure that all 10 statutorily required categories are represented. In general, plans that
are required to offer the EHB must model their benefits package after the state’s selected
benchmark plan.36

33 42 U.S.C. §18032.
34 42 U.S.C. §18022.
35 The 10 categories are ambulatory patient services; emergency services; hospitalization; maternity and newborn care;
mental health and substance use disorder services, including behavioral health treatment; prescription drugs;
rehabilitative and habilitative services and devices; laboratory services; preventive and wellness services and chronic
disease management; and pediatric services, including oral and vision care.

Private Health Insurance Market Reforms in the Affordable Care Act (ACA)

ACA requirement for plans to cover the EHB does not prohibit states from maintaining or
establishing state-mandated benefits. In fact, the Secretary of HHS has determined that state-
required benefits enacted on or before December 31, 2011, are considered part of the EHB for at
least 2014 and 2015. However, any state that requires plans to cover benefits beyond EHBs and
what was mandated by state law prior to 2012 must assume the total cost of providing those
additional benefits.37 In other words, states have to defray the cost of any mandated benefits
enacted after December 31, 2011.
No Cost-Sharing for Preventive Health Services
Plans are required to provide coverage for certain preventive health services without imposing
cost-sharing.38 The preventive services include the following minimum requirements:39
• evidence-based items or services that have in effect a rating of “A” or “B” from
the United States Preventive Services Task Force (USPSTF);40
• immunizations that have in effect a recommendation from the Advisory
Committee on Immunization Practices of the Centers for Disease Control and
Prevention (CDC);41
• evidence-informed preventive care and screenings (for infants, children, and
adolescents) provided for in the comprehensive guidelines supported by the
Health Resources and Services Administration (HRSA);42 and
• additional preventive care and screenings for women not described by the
USPSTF, as provided in comprehensive guidelines supported by HRSA.43

additional benefits for qualified health plans (QHP), which are plans that must meet the certification standards to be
offered through an exchange.

41 The Advisory Committee on Immunization Practices consists of 15 experts in fields associated with immunization
who have been selected by the Secretary of HHS to provide advice and guidance to the Secretary and the CDC on the
control of vaccine-preventable diseases. The committee develops recommendations for the routine administration of
vaccines to children and adults in the civilian population; recommendations include age for vaccine administration,
number of doses and dosing interval, and precautions and contraindications. For more information, see

approved contraceptive methods and sterilization procedures. The requirement to cover contraceptive services has been
a source of controversy. A recent decision from the Supreme Court in Burwell v. Hobby Lobby Stores, Inc. allowed
closely held corporations to avoid penalties for noncompliance with the requirement. For more details, see CRS Report

Private Health Insurance Market Reforms in the Affordable Care Act (ACA)

Additional services not recommended by the USPSTF may be offered, but are not required. For
the purposes of this provision and others in federal law, ACA negates the November 2009
USPSTF recommendation that women receive routine screening mammograms beginning at age
50. As a result, plans are required to cover screening mammograms beginning at age 40, based on
the prior USPSTF recommendation.
A plan that has a network of providers is not required to provide coverage for a recommended
preventive service that is delivered by an out-of-network provider, and the plan may impose cost-
sharing requirements for a recommended preventive service delivered out-of-network.
Additionally, if a recommended preventive service does not specify the frequency, method,
treatment, or setting for the service, then the plan can determine coverage limitations by relying
on established techniques and relevant evidence.
Coverage of Preexisting Health Conditions
ACA prohibits plans from excluding coverage for preexisting health conditions.44 In other words,
plans may not exclude benefits based on health conditions for any individuals. A “preexisting
health condition” is a medical condition that was present before the date of enrollment for health
coverage, whether or not any medical advice, diagnosis, care, or treatment was recommended or
received before such date.
Cost-Sharing Limits
Limits for Annual Out-of-Pocket Spending
ACA places annual limits on out-of-pocket spending.45 The limits apply only to in-network
coverage of the essential health benefits (EHB).46 In 2014, the limits cannot exceed existing limits
specified in the tax code applicable to certain high-deductible health plans: $6,350 for self-only
coverage and $12,700 for coverage other than self-only.47
The Departments (HHS, Labor, and Treasury) have provided that group plans that utilize more
than one service provider to administer benefits may allow separate out-of-pocket limits. For
example, if a group plan utilizes one service provider to administer major medical coverage and
another to administer a separate pharmacy benefit, the major medical coverage may have the
maximum out-of-pocket limit ($6,350 or $12,700) and the pharmacy benefit may also have the

44 42 U.S.C. §300gg-3.
45 ACA also included deductible limits for plans offered in the small group market—generally prohibiting these plans
from having deductibles greater than $2,000 for self-only coverage and $4,000 for any other coverage in 2014.
However, the Protecting Access to Medicare Act of 2014 (P.L. 113-93) repealed this provision, thereby removing the
limitation on deductibles for plans offered in the small group market.
46 Certain types of plans—self-insured plans and plans offered in the large group market—must comply with this
requirement but do not have to offer the EHBs. HHS has indicated that such plans must use a permissible definition of
EHB (including any state-selected EHB benchmark plans) to determine whether they comply with the requirement.
47 42 U.S.C. §18022.

maximum out-of-pocket limit. This option is available only for the first plan year that begins on
or after January 1, 2014, and it is not an option for nongroup plans.48
Minimum Actuarial Value Requirements
ACA requires plans to tailor cost-sharing to comply with one of four levels of actuarial value.49
Actuarial value (AV) is a summary measure of a plan’s generosity, expressed as the percentage of
total medical expenses that are estimated to be paid by the issuer for a standard population and set
of allowed charges.50 In other words, AV reflects the relative share of cost-sharing that may be
imposed. On average, the lower the AV the greater the cost-sharing for the enrollee.51
Each level of plan generosity is designated according to a precious metal and corresponds to a
specific actuarial value:
• Bronze: 60% AV
• Silver: 70% AV
• Gold: 80% AV
• Platinum: 90% AV
Prohibition of Lifetime Limits and Annual Limits
Prior to ACA, plans were generally able to set lifetime and annual limits—dollar limits on how
much the plan would spend for covered health benefits either during the entire period an
individual was enrolled in the plan (lifetime limits) or during a plan year (annual limits).52 Under
ACA, both lifetime and annual limits are prohibited; the limits apply specifically to essential
health benefits (EHB).53 Plans are permitted to place lifetime and annual limits on covered
benefits that are not considered EHBs, to the extent that such limits are otherwise permitted by
federal and state law.

ebsa/faqs/faq-aca18.html.
49 42 U.S.C. §18022.
50 While actuarial value (AV) is a useful measure, it is only one component that addresses the value of any given
benefit package. AV, by itself, does not address other important features of coverage, such as total (dollar) value,
network adequacy, and premiums.
51 While actuarial value is calculated based on costs for an entire population, it does not mean that every person
enrolled in the same plan will have the same expenses, because in any given group some people use relatively little care
while others use a great deal. Given that actuarial value reflects cost-sharing, such a measure may be useful to
consumers when comparing different health plans.
52 42 U.S.C. §300gg-11.
53 Certain types of plans—grandfathered plans, self-insured plans, and plans offered in the large group market—must
comply with these requirements but do not have to offer the EHBs. HHS has indicated that such plans must use a
permissible definition of EHB (including any state-selected EHB benchmark plans) to determine whether they comply
with the requirements.

Consumer Assistance and Other Patient Protections
Internet Portal to Assist Consumers in Identifying Coverage Options
The Secretary of HHS, in consultation with the states, is required to establish an Internet portal
for the public to easily access affordable and comprehensive coverage options.54 The portal is
required to provide, at minimum, information on the following coverage options: health plans
offered in the private insurance market; Medicaid and the State Children’s Health Insurance
Program (CHIP); high risk pools; and small group health plans. The Internet portal,
www.healthcare.gov, launched on July 1, 2010.
Summary of Benefits and Coverage
The ACA required the Secretaries (HHS, Labor, and Treasury) to develop standards for plans with
respect to providing their enrollees with a summary of benefits and coverage (SBC) and to
periodically review and update the standards.55 Table 1 summarizes the standards for the SBC.

paper or electronic form. Enrollees must be given notice of any material changes in benefits no
later than 60 days prior to the date that the modifications would become effective. Any entity that
willfully fails to provide the information required is subject to a fine of not more than $1,000 for
each such failure, defined as each enrollee that did not receive the required information. ACA also
requires that plans provide a uniform glossary of terms commonly used in health insurance
coverage (e.g., coinsurance) to enrollees upon request.56
Medical Loss Ratio (MLR)
Under ACA, health plans are required to submit to the Secretary of HHS a report concerning the
percentage of premium revenue spent on medical claims (“medical loss ratio,” or MLR).57 The
MLR calculation includes adjustments for health quality costs, taxes, regulatory fees, and other
factors. The law requires plans in the individual and small group markets to meet a minimum
MLR of 80%; for large groups, the minimum MLR is 85%.58 States are permitted to increase the
percentages, and the Secretary of HHS may adjust the state percentage for the individual market
if it is determined that the application of a minimum MLR of 80% would destabilize the
individual market within the state.59 Health plans whose MLR falls below the specified limit must
provide rebates to policyholders on a pro rata basis. Any required rebates must be paid to
policyholders by August of that year.60
Appeals Process
ACA requires that plans implement an effective appeals process for coverage determinations and
claims.61 The process at a minimum must
• have an internal claims appeals process;
• provide notice to enrollees of available internal and external appeals processes,
and the availability of any applicable assistance; and
• allow an enrollee to review their file, present evidence and testimony, and to
receive continued coverage pending the outcome.
To comply with the requirements for the internal claims appeals process, group plans are
expected to initially incorporate the claims and appeals procedures previously established under
federal law62 and will update their processes in accordance with any standards established by the

58 Until 2016, ACA allows states to define the small group market as employers who have up to and including 50
employees or up to and including 100 employees; in 2016, the small group market will be defined as employers who
have up to and including 100 employees.

Secretary of Labor. Individual health plans will comply with internal claims and appeals
procedures set forth under applicable law and updated by the Secretary of HHS.
In order to comply with the requirements for the external appeals process, plans must comply
with a state’s external review process, provided that process includes, at a minimum, the
consumer protections set forth in the Uniform External Review Model Act promulgated by the
National Association of Insurance Commissioners (NAIC). If a state’s review process does not
meet the minimum requirements, the state must implement a process that meets the standards
established by the Secretary of HHS, and plans must comply with such a process.63
Patient Protections
Plans are subject to three ACA requirements relating to the choice of health care professionals
and one ACA requirement relating to benefits for emergency services.64
Regarding the choice of health care professionals, a plan that requires or allows an enrollee to
designate a participating primary care provider is required to permit the designation of any
participating primary care provider who is available to accept the individual. This same provision
applies to pediatric care for any child who is a plan participant. A plan that provides coverage for
obstetrical or gynecological care cannot require authorization or referral by the plan or any person
(including a primary care provider) for a female enrollee who seeks obstetrical or gynecological
care from an in-network health care professional who specializes in obstetrics or gynecology.
If the plan covers services in an emergency department of a hospital, the plan is required to cover
those services without the need for any prior authorization and without the imposition of coverage
limitations, irrespective of the provider’s contractual status with the plan. If the emergency
services are provided out-of-network, the cost-sharing requirement will be the same as the cost-
sharing for an in-network provider.
Nondiscrimination Regarding Clinical Trial Participation
ACA does not allow health plans to
• prohibit “qualified individuals” from participating in an approved clinical trial;
• deny, limit, or place conditions on the coverage of routine patient costs associated
with participation in an approved clinical trial; or
• discriminate against “qualified individuals” on the basis of their participation in
approved clinical trials.65

(...continued)
notice in writing to any participant or beneficiary whose claim for benefits under the plan has been denied, setting forth
the specific reasons for such denial, written in a manner calculated to be understood by the participant, and to afford a
reasonable opportunity to any participant whose claim for benefits has been denied for a full and fair review by the
appropriate named fiduciary of the decision denying the claim.

Private Health Insurance Market Reforms in the Affordable Care Act (ACA)

ACA defines qualified individual, for purposes of this provision, as an individual who is eligible
to participate in an approved clinical trial for treatment of cancer or other life-threatening disease
or condition, and who either has a referring health care provider who has concluded that the
individual’s participation is appropriate, or who provides medical and scientific information
establishing that participation in a clinical trial would be appropriate.
Plan Requirements Related to Health Care Providers
Nondiscrimination Regarding Health Care Providers
ACA imposes nondiscrimination requirements with respect to health care providers.66 Plans are
not allowed to discriminate, with respect to participation under the plan, against any health care
provider who is acting within the scope of that provider’s license or certification under applicable
state law. This provision does not require that a plan contract with any health care provider
willing to abide by the plan’s terms and conditions, and the provision cannot be read as
preventing a plan or the Secretary of HHS from establishing varying reimbursement rates for
providers based on quality or performance measures.
Reporting Requirements Regarding Quality of Care
Beginning upon ACA enactment, and concluding no later than two years after enactment, the
Secretary of HHS (Secretary) must develop quality reporting requirements for use by specified
plans.67 The Secretary must develop these requirements in consultation with experts in health care
quality and other stakeholders. The Secretary is also required to publish regulations governing
acceptable provider reimbursement structures not later than two years after ACA enactment. Not
later than 180 days after these regulations are promulgated, the U.S. Government Accountability
Office (GAO) is required to conduct a study regarding the impact of these activities on the quality
and cost of health care. To date, the Secretary has not published the required regulations;
therefore, the required GAO report has not been published either.
Once the reporting requirements are implemented, plans will annually submit, to the Secretary
and enrollees, a report addressing whether plan benefits and reimbursement structures do the
following: (1) improve health outcomes through the use of quality reporting, case management,
care coordination, and chronic disease management; (2) implement activities to prevent hospital
readmissions and to improve patient safety and reduce medical errors; and (3) implement
wellness and health promotion activities. The Secretary is required to make these reports
available to the public, and is permitted to impose penalties for noncompliance.
Wellness and health promotion activities include personalized wellness and prevention services,
and specifically efforts related to smoking cessation, weight management, stress management,
physical fitness, nutrition, heart disease prevention, healthy lifestyle support, and diabetes
prevention. These services may be made available by entities (e.g., health care providers) who

conduct health risk assessments or who provide ongoing face-to-face, telephonic, or web-based
intervention efforts for program participants.68

68 With respect to gun rights, a wellness or promotion activity cannot require disclosure or collection of any
information in relation to (1) the presence or storage of a lawfully possessed firearm or ammunition in the residence or
on the property of an individual, or (2) the lawful use, possession, or storage of a firearm or ammunition by an
individual. A health plan issued in accordance with the law is prohibited from increasing premium rates, denying health
insurance coverage, and reducing or withholding a discount, rebate, or reward offered for participation in a wellness
program on the basis of or on reliance on the lawful ownership, possession, use or storage of a firearm or ammunition.

Source: CRS Analysis of ACA and its implementing regulations.
Notes: N.A. indicates that the reform is not applicable to that type of health insurance plan. These market reforms do not apply to retiree-only health coverage (see
footnote 9). The reform “Internet Portal to Assist Consumers in Identifying Coverage Options” is not included in this table because the reform does not apply to health
plans. There are other health insurance reforms that are currently effective under federal law. This table lists only ACA’s market reforms; therefore, it is not intended to be
a comprehensive listing of al federal health insurance requirements and standards.
a. A grandfathered plan refers to an existing group health plan or a health insurance plan/policy in which at least one individual is enrolled since March 23, 2010. To
maintain grandfathered status, a plan must avoid certain changes to benefits, cost-sharing, employer contributions, and access to coverage.
b. Health insurance can be provided to a group of people that are drawn together by an employer or other organization, such as a trade union. Such groups are generally
formed for some purpose other than obtaining insurance, like employment. When insurance is provided to a group, it is referred to as “group coverage” or “group
insurance.” In the group market, the entity that purchases health insurance on behalf of a group is referred to as the plan “sponsor.”
CRS-18


c. Prior to ACA, large groups were defined as groups with more than 50 workers. For plan years beginning before January 1, 2016, a state may elect to keep the previous
definition of large groups, or change the definition to include those groups with more than 100 workers, applicable to ACA-created exchanges and market reforms.
For plan years beginning on or after January 1, 2016, large groups must be defined as groups with more than 100 workers.
d. Prior to ACA, small groups were defined as groups with 2 to 50 workers, although some states also included self-employed individuals ("groups of one”) in the small
group market. For plan years beginning before January 1, 2016, a state may elect to keep the previous definition of small groups, or change the definition to include
those groups with 100 or fewer workers, applicable to ACA-created exchanges and market reforms. For plan years beginning on or after January 1, 2016, smal groups
must be defined as groups with 100 or fewer workers.
e. A fully insured health plan is one in which the plan sponsor purchases health coverage from a state-licensed insurance carrier; the carrier assumes the risk of paying the
medical claims of the sponsor’s enrol ed members.
f.
Self-insured plans refer to health coverage that is provided directly by the organization seeking coverage for its members (e.g. a firm providing health benefits to its
employees). Such organizations set aside funds and pay for health benefits directly. Under self-insurance, the organization bears the risk for covering medical claims.
g. Consumers who are not associated with a group can obtain health coverage by purchasing it directly from an insurance carrier in the individual (or nongroup) health
insurance market.
h. The final rule regarding rate review specified that this provision would apply only to nongroup and fully insured, small group coverage, and not to large groups.
