Military Medical Care: Mitigating Impacts 
From Medical Unit Deployments 
Updated September 22, 2020 
Contingency and peacetime missions consistently require temporary reassignment of military medical 
personnel from military treatment facilities (MTF) to a deployable medical unit. In certain instances, MTF 
services may be limited in times of war, operations other than war, natural disasters, or other 
contingencies. This restriction is not uncommon. Notwithstanding these circumstances, the Department of 
Defense (DOD) is required to provide statutory health benefits to its eligible beneficiaries by mitigating 
fluctuations in MTF service
s. Chapter 55 of Title 10, U.S. Code, specifies health care entitlements for 
military personnel, retirees, and their families. The delivery of those benefits can vary based on current or 
projected military operations and the availability of medical personnel in MTFs.  
Listed below are two examples of MTF services having been, or soon to be, limited as a result of military 
medical deployments. 
  On November 1, 2018, DOD
 approved a request for military assets (e.g., planning, 
engineering, transportation, logistics, and medical) in support of the Department of Homeland 
Security and U.S. Customs and Border Protection (CBP). Military medical personnel 
assigned to numerous U.S. Army MTFs were
 reassigned to deployable medical units tasked 
to support CBP. 
  On March 18, 2020, DOD
 announced preparations for the deployment of the U.S. Navy’s 
hospital shi
ps, USNS COMFORT and USNS MERCY, to support the domestic response to 
the Coronavirus (COVID-19). Approximately 900 medical personnel primarily from
 Naval 
Medical Center Portsmouth and Naval Medical Center San Diego, respectively, staffed each 
ship. In May 2020, both ships returned to their respective homeports, but remain available for 
future tasking.  
To understand the impact of these deployments on MTF services, it may be helpful to first consider how 
t
he Military Health System (MHS) delivers care and staffs its MTFs.  
How is health care delivered in the MHS? 
The MHS offers health care t
o 9.6 million beneficiaries (i.e., active duty servicemembers, eligible 
members of the National Guard and Reserve, retirees, and their family members) in MTFs or through

civilian providers participating in DOD’s health care program
—TRICARE. MTFs range in size and 
capability, from small primary care clinics to large academic medical centers. However, they are generally 
tailored to ensure military personnel are medically ready. 
TRICARE pays for care delivered by civilian providers. There are three main benefit plans: a health 
maintenance organization optio
n (TRICARE Prime), a preferred provider option
 (TRICARE Select), and 
a Medicare wrap-around option 
(TRICARE for Life) for Medicare-eligible retirees. 
How are military medical personnel selected for deployment? 
MTFs are staffed by military, civil service, and contract personnel. Military personnel are subject to 
mobilization, deployment, temporary duty, or reassignment based on requirements established by a 
combatant commander and tasking by the Joint Chiefs of Staff or their respective Service. Requirements 
and tasking may occur during peacetime or contingencies, with short or long-term notice. 
At some MTFs, preidentified military personnel are concurrently assigned to deployable medical units 
(e.g., hospital ship, combat support hospital, or medical logistics company). In general, these assignments 
allow military personnel to work at an MTF during nondeployment periods, and be reassigned to their 
deployable medical unit if activated. 
Military personnel not concurrently assigned to a deployable medical unit may also deploy with another 
medical unit or as a
n individual augmentee. These individuals are typically ordered to deploy because of a 
unique skill set or clinical expertise required for a specific mission. 
The length of reassignment is dependent on the deployment mission, but can typically range from a few 
days to nine months. 
How are MTF services impacted when military medical personnel deploy? 
When military staff deploy, they leave a staffing gap at the MTF. This gap can result in reduced MTF 
capabilities, reduced capacity to provide health care services, and longer wait times. Loss of, or degraded 
MTF capabilities and capacity are dependent on the number and type of personnel deployed. In a previous 
USNS COMFORT deployment
, Naval Medical Center Portsmouth reported impacts that include “longer 
wait times for appointments for primary and some specialty care services, as well as increases in out-
patient pharmacy wait times.” 
How do MTFs mitigate the staffing gap? 
To mitigate the staffing gap, MTF commanders can use a range of options. 
Table 1. Options to Mitigate MTF Loss of Personnel 
Mitigation Options 
Description 
Use the reserve component 
 
Call up reserve medical personnel to fil  gapped positions 
Use contract personnel 
 
Initiate a new, or modify an existing, health care staffing contract to fil  gapped 
positions 
Use civil service personnel 
 
Hire additional civil service personnel or expand employee overtime opportunities

Decrease clinical capabilities that would typically be available (e.g., reduce number 
Reduce MTF health care services 
of staffed hospital beds and operating rooms or discontinue clinical services) 
offered and refer patients to 
TRICARE 
 
Prioritize MTF care available according to
 Health Affairs Policy 11-005 
 
Refer patients to TRICARE for services no longer available in the MTF 
MTF commanders may use a mitigation strategy that incorporates multiple options listed above; however, 
they may also be constrained by their budgets. Additional funding may be available from an MTF’s 
parent organization. 
In addition to MTF mitigation strategies, what is TRICARE’s role during military 
medical deployments? 
The Defense Health Agency contracts three managed care entities to administer DOD’s health 
benefits through the TRICARE program.
 Each contractor is required to “ensure that health care 
services are continuously available for TRICARE-eligible beneficiaries” when MTFs are 
impacted by military medical deployments. This is accomplished through an
 individual 
agreement between a TRICARE contractor and an MTF that outlines how health care services 
will be made available during an event that impacts MTF staffing. Individual agreements may 
also include details about how the TRICARE contractor will expand its provider networks to 
accommodate an increase in patient workload due to MTF staffing gaps caused by a military 
medical deployment. The TRICARE contractors must also continue to meet access to care 
standards as required by
 32 C.F.R. §199.17(p)(5) a
nd Health Affairs Policy 11-005.
