What is TRICARE For Life? The complete guide for retired military

TRICARE For Life is the lifetime health benefit retired service members and their qualifying family members earned through service. Created by Congress in 2001 and effective October 1, 2001, TFL was designed to be the Medicare wraparound for the military retiree community — closing the gap between what Medicare pays (about 80% on Part B services) and the patient's share (the remaining 20%).

It is not a separate insurance policy you shop for. It is a benefit that activates automatically when you have the right pieces in place: Medicare Parts A and B, and a current DEERS enrollment.

Who can use TRICARE For Life

You are eligible for TFL if you fall into one of these categories and are entitled to Medicare Part A and enrolled in Part B:

• Medicare-eligible uniformed services retirees (Army, Navy, Marine Corps, Air Force, Space Force, Coast Guard, NOAA Commissioned Corps, USPHS Commissioned Corps)
• Medicare-eligible spouses of active duty, retired, or deceased uniformed services members
• Medicare-eligible survivors of uniformed services members
• Medal of Honor recipients and their eligible family members
• Certain former spouses who qualify under the 20/20/20 rule (20 years of marriage, 20 years of creditable service, and 20 years of overlap)
• Medicare-eligible dependent adult children with conditions that qualified them for Medicare before 65

You must be registered in DEERS (the Defense Enrollment Eligibility Reporting System). If DEERS is not current, claims will not process correctly. Update DEERS at any ID card office or through milConnect at milconnect.dmdc.osd.mil.

What TFL costs

This is the simplest cost structure in all of American healthcare for a benefit this comprehensive:

You do pay the Medicare Part B premium (typically deducted from your Social Security check) and modest TRICARE Pharmacy copays. That is essentially the full cost of having TFL.

How TFL coordinates with Medicare

The mechanics:

1. You see a Medicare-participating provider.
2. The provider bills Medicare.
3. Medicare pays its share (commonly 80% of the approved amount for Part B).
4. Medicare's claim crosses over electronically to WPS (the TFL claims processor) the same day.
5. WPS pays the remaining Medicare cost-share — the deductible and 20% coinsurance for covered services.
6. You receive a Medicare Summary Notice and a TFL Explanation of Benefits. Most show a $0 patient responsibility.

The result: at participating providers, for services covered by both Medicare and TFL, you generally owe nothing.

What TFL does NOT cover

Even with TFL, some categories of care are out of pocket or require other coverage:

• Routine dental (cleanings, fillings, crowns, dentures). Solution: FEDVIP dental plan through BENEFEDS or a Medicare Advantage plan that includes dental.
• Routine vision (eye exams for glasses, glasses themselves). Solution: FEDVIP vision plan or MA plan that includes vision.
• Hearing aids and routine hearing exams. Solution: VA (if service-connected), MA plan, or out of pocket.
• Long-term custodial care (nursing-home room and board for non-skilled care). Solution: long-term care insurance or personal planning.
• Most cosmetic services
• Care from providers who have formally opted out of Medicare

What TFL DOES uniquely cover

A few areas where TFL is broader than Medicare or pays where Medicare does not:

• Overseas care — Medicare generally does not pay outside the U.S.; TFL provides coverage through the TRICARE Overseas Program in many circumstances.
• Certain skilled nursing scenarios where Medicare benefits exhaust.
• Some medical care that Medicare does not cover but TRICARE does — TFL pays as if it were TRICARE Select primary.

When TFL pays primary (Medicare-noncovered services), TRICARE Select deductibles and cost-shares apply.

Who runs TFL

• Defense Health Agency (DHA) owns the program at the Department of Defense.
• Wisconsin Physicians Service (WPS) Military and Veterans Health is the contracted claims processor. WPS issues TFL EOBs and handles claims questions.
• Express Scripts administers the TRICARE Pharmacy Program for outpatient prescriptions.

When something goes wrong with a claim, the back-of-EOB phone numbers are your starting point — Medicare for the Medicare side and WPS for the TFL side.

FAQs

• 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.
• Who is eligible for TRICARE For Life?Retired uniformed service members, eligible spouses and widows/widowers, certain former spouses, and Medal of Honor recipients — all entitled to Medicare Part A and enrolled in Part B, with current DEERS status.
• 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.
• Does my spouse keep TFL if I die first?Yes. Eligible surviving spouses keep TRICARE For Life as long as they remain enrolled in Medicare Part B and DEERS reflects survivor status. They don't lose TFL by becoming a survivor.
• What does TRICARE For Life actually cover?TFL is a wraparound. For services Medicare and TFL both cover, TFL pays nearly all remaining cost-shares. For Medicare-only services, TFL still acts as secondary. For TFL-only services (very few), TFL pays as primary.
• Does TFL cover a skilled nursing facility stay?Yes. After a qualifying 3-day inpatient hospital stay, Medicare covers up to 100 days of SNF care and TFL pays the days-21–100 coinsurance.
