US Family Health Plan (USFHP)
A TRICARE Prime option delivered by designated civilian provider networks in specific U.S. regions — Medicare-eligible enrollees disenroll at 65 and move to TFL.
Also known as: USFHP, US Family Health Plan
Quick answer
The US Family Health Plan is a TRICARE Prime option provided by six designated not-for-profit health systems in defined service areas (parts of the Northeast, Mid-Atlantic, Gulf Coast, Puget Sound, etc.). It offers Prime-style managed care through a regional network rather than the standard TRICARE regional contractor.
Why it matters
USFHP rules differ from standard TRICARE Prime in one critical way: USFHP enrollees who are Medicare-eligible must disenroll from USFHP and transition to TFL. There is no longer a 'USFHP after 65' option for newly eligible beneficiaries.
Why this matters at age 65
If you are on USFHP, plan your Medicare A and B enrollment carefully. Coordinate with your USFHP designated provider so disenrollment aligns with your Medicare effective date — gaps can occur if dates don't line up.
When you'll encounter it
Every USFHP visit, and the planning window 6–12 months before age 65 if you are on USFHP today.
Impact on Medicare
USFHP enrollment ends at Medicare eligibility for newly eligible beneficiaries. Medicare then becomes primary.
Impact on TRICARE For Life
TFL replaces USFHP at age 65 on the same automatic terms — Medicare A and B + DEERS = TFL.
Military-specific context
USFHP designated providers include systems like Johns Hopkins, Brighton Marine, Martin's Point, CHRISTUS Health, Pacific Medical Centers, and St. Vincent Catholic Medical Centers. Each operates only in its assigned service area.
Common misconceptions
- "I can keep USFHP past 65." — Newly Medicare-eligible beneficiaries cannot remain on USFHP — they move to TFL.
Common mistakes to avoid
- Assuming the USFHP doctor will continue as your provider automatically — verify they accept Medicare before age 65.
- Missing the disenrollment window because Medicare A or B wasn't reflected in DEERS in time.
Real-world scenario: A retired Army E-6 on USFHP in the Mid-Atlantic turns 65.
USFHP disenrolls him at month-end. Medicare A and B begin the next day. TFL activates automatically. His former USFHP primary-care doctor accepts Medicare, so he continues there with Medicare primary and TFL secondary.

- Is there an enrollment fee for TRICARE For Life?No. TFL has no enrollment fee and no monthly premium. The only premium you pay is for Medicare Part B.
- Can I keep going to the military hospital after 65?Only on a space-available basis. Active duty and Prime enrollees come first. Most retirees on TFL transition fully to civilian Medicare providers.
- My doctor says they don't take TRICARE. What now?Ask the right question: 'Do you accept Medicare?' On TFL, Medicare is your network. Any Medicare-participating provider can bill TFL as secondary, even if they say they don't 'take TRICARE.'
- Does TFL cover long-term care or a nursing home?No. Medicare and TFL only cover short-term skilled care after a qualifying hospital stay. Custodial long-term care (assisted living, nursing home for daily living help) isn't covered by either.
- What if my doctor doesn't take Medicare?If they opted out of Medicare, neither Medicare nor TFL will pay and you'll owe the full bill. Find a Medicare-participating provider instead.
