Key points
- Eligible TRICARE For Life beneficiaries need both Medicare Part A and Part B; Part C and Part D are not required for TFL.[1][2]
- For services both programs cover, Medicare generally pays first and TRICARE For Life pays last. Costs can remain for services not covered by both programs.[2][3]
- The standard Medicare Part B premium is $202.90 per month in 2026; higher-income beneficiaries may pay more, and you must keep paying Part B to keep TFL.[4][2]
- Some Medicare Advantage plans may help pay all or part of the Part B premium, but this plan-specific reduction varies by plan, county, and year; compare the whole plan.[5][6][7]
- With Medicare Advantage, TFL remains secondary, but the plan's network, copayments, and claims process can affect how you receive care.[1]
Watch: Why you need Part B to keep TRICARE For Life
If you have TRICARE For Life, Medicare Parts A and B are the foundation of your coverage. Medicare generally pays first for services both programs cover, and TRICARE For Life pays last. Part C and Part D are not required for TFL, but choosing Medicare Advantage can change networks, copayments, and the way claims are handled.[1][2]
What TRICARE For Life requires
TRICARE For Life is Medicare-wraparound coverage for eligible TRICARE beneficiaries who have Medicare Part A and Part B. Coverage is automatic when both parts are effective, and you must continue paying your Part B premium. You do not need Medicare Part C or Part D to have TFL.[1][2]
If Part B is not in effect, you may lose TFL eligibility while that gap lasts. TFL starts automatically when both Part A and Part B are effective, so ask Social Security and TRICARE about your individual reinstatement timing rather than assuming coverage will restart immediately.[2]
How Medicare and TRICARE For Life pay for care
For a service covered by both Medicare and TRICARE, Medicare generally pays first and TFL pays last. When both programs cover the service, you may have no out-of-pocket cost. That is not a promise for every bill: deductibles, cost-shares, provider status, claim circumstances, and services covered by only one program can still create costs.[2][3]
| Situation | What to expect |
|---|---|
| Medicare and TRICARE both cover the service | Medicare generally pays first; TFL pays last for the remaining covered amount. |
| Only Medicare covers the service | Medicare's deductible and cost-sharing rules may apply. |
| Only TRICARE covers the service | TRICARE's deductible and cost-sharing rules may apply. |
| Neither program covers the service | You may be billed for the charge. |
Review the current TRICARE cost table and your plan documents before receiving care.[2]
The 2026 Part B premium and late-enrollment penalty
The standard Medicare Part B premium is $202.90 per month in 2026; higher-income beneficiaries may pay more. Confirm the current amount at Medicare.gov or CMS because premiums can change annually. Keeping Part B active is required for TFL.[4][2]
Medicare's Initial Enrollment Period lasts seven months: the three months before you turn 65, your birthday month, and the three months after. The Part B late-enrollment penalty is generally an extra 10% for each full 12-month period you could have had Part B, usually for as long as you have Part B. VA health care is not current-employment group coverage for the usual Part B Special Enrollment Period; COBRA and retiree coverage do not create that usual SEP.[9][10][8]
How Part B premium reductions work
Some Medicare Advantage plans may help pay all or part of your Part B premium. This is a plan-specific Part B premium reduction, not a refund, universal payment, or cash benefit. Availability varies by plan, county, and year; some plans offer no reduction. If available, it may appear as a lower Social Security or Railroad Retirement deduction or a smaller Medicare bill, and it can take time to begin.[5][12][6]
You still must pay Part B to benefit, and a reduction does not eliminate premiums or cost sharing. Compare the plan's premium, network, deductible, copayments, prior authorization, drug coverage, and yearly out-of-pocket limit in Medicare Plan Compare and the Evidence of Coverage. A reduction is only one part of the decision.[5][13][7]
What changes if you choose Medicare Advantage?
Medicare Advantage (Part C) is optional. If a TFL beneficiary enrolls, nonemergency care generally must come from the Medicare Advantage plan's network. You may pay copayments at the time of service, and you may need to file paper claims with TRICARE for reimbursement. TFL remains secondary, but the plan's network, cost-sharing, covered-service rules, and claims process matter.[1]
Medicare Advantage rules apply to the Medicare-covered care the plan manages; they do not change VA eligibility or VA authorization rules. VA health care and Medicare are separate programs, and you generally choose which benefits to use for each visit.[8][3]
Enrollment steps for military retirees
- Confirm your coverage category Separate TRICARE For Life from VA health care, CHAMPVA, employer coverage, retiree coverage, and COBRA. Their enrollment rules are not interchangeable.[1][8]
- Enroll in Parts A and B on time If you are not automatically enrolled, contact Social Security and use your seven-month Initial Enrollment Period. TFL advises enrolling in Parts A and B at least two months before age 65 to help avoid a coverage gap.[14][9][1]
- Keep Part B active Continue paying the Part B premium and check that your Medicare information is current in the systems used by TRICARE.[2]
- Compare optional plans carefully If considering Medicare Advantage, compare networks, provider rules, copayments, claims procedures, drug coverage, and out-of-pocket costs—not just a Part B premium reduction.[15][13][1]
A note about VA health care
Having Medicare or TRICARE does not by itself change your VA health care eligibility. VA encourages eligible veterans to sign up for Medicare, but VA and Medicare do not pay for the same item or service. You choose which benefit to use, and non-VA community care generally must be authorized by VA first.[8][16][3]
If you need emergency care at a non-VA facility, call 911. VA emergency-care rules include using an emergency department and notifying VA within 72 hours, along with other eligibility requirements.[17]

Common questions
Do I need Medicare Part B to keep TRICARE For Life?
Yes. Eligible TFL beneficiaries need both Medicare Part A and Part B. Part C and Part D are not required for TFL.[1][2]
Does TRICARE For Life pay after Medicare?
For services both programs cover, Medicare generally pays first and TFL pays last. Costs can remain when a service is covered by only one program or by neither.[2][3]
Can Medicare Advantage work with TRICARE For Life?
Yes, but the Medicare Advantage plan's network, copayments, and claims process apply. Nonemergency care generally must use the plan's network, and paper claims to TRICARE may be needed.[1]
