Medicare TRICARE for Life: Wraparound Coverage

Medicare TRICARE for Life is wraparound coverage for uniformed-service retirees, eligible family members, survivors, and certain former spouses who have Medicare Part A and Part B. [1][2] In North Carolina, as everywhere else, Medicare pays first for covered care when you are not on active duty, then TRICARE For Life (TFL) pays second. [1] You must keep Part B to stay TRICARE-eligible. If you skip Part B, drop it, or stop paying the premium, you lose TFL. [3]

What TRICARE For Life is, and who it covers

TFL is not a private "veteran Medicare" product. It is the TRICARE benefit that starts automatically once you show as TRICARE-eligible in the Defense Enrollment Eligibility Reporting System (DEERS) and you have both Medicare Part A and Part B. [2][4] There is no TFL enrollment form and no TFL enrollment fee. Coverage begins the first day both parts are in effect. [2][4]

Medicare describes TFL as expanded medical coverage for Medicare-eligible uniformed services retirees age 65 or older, their eligible family members and survivors, and certain former spouses. [1] TRICARE adds that TFL is available regardless of age or place of residence, as long as you are TRICARE-eligible and have Part A and Part B. [2] Active duty service members and active duty family members with Medicare stay in their current TRICARE plan. They do not move to TFL. [4]

Proof of coverage is your Medicare card and your Uniformed Services ID card. There is no separate TFL card. [2] In the United States and U.S. territories you may see any Medicare-certified provider, including civilian doctors in Greensboro and across the Piedmont. You may also use a military hospital or clinic if space is available. [2][5]

TFL follows the person, not the household. TRICARE states that coverage is only for people who have Medicare and who are TRICARE-eligible, and that it does not extend to family members. [2] A spouse still needs their own Part A and Part B before TFL starts for them. For a retired service member or a retiree's family member who is 65 or older, TRICARE's plan-choice table is plain: Medicare Part A only means you are not TRICARE-eligible. Part A and Part B means TFL. [6] Keep DEERS current. The DMDC/DEERS Support Office can confirm eligibility at 800-538-9552. [4]

Why Part B is required

Part A is hospital insurance. Most people pay no Part A premium because they (or a spouse) paid Medicare taxes long enough while working, generally at least 10 years. [7] Part B is medical insurance for doctor visits, outpatient care, and many other services. It has a monthly premium based on income. [7][8]

For TFL, both parts are required. TRICARE's retiree page states that if you are eligible for Medicare Part A, you must have Part B to keep TRICARE, even if you live overseas. You lose TRICARE if you do not have Part B, if you drop Part B, or if you fail to pay your Part B premiums. [3] The same rule applies to medically retired members and their families, and to retired National Guard and Reserve members (and their families) ages 60 and older. [3]

TFL has no enrollment fee. The cost you do pay is the Part B premium. [8][9] For 2026, Medicare lists the standard Part B premium as $202.90 a month, or higher depending on income. You pay it each month even if you do not use Part B services that month. [7]

If you already receive Social Security or Railroad Retirement Board benefits, Part A and Part B usually start automatically on the first day of the month you turn 65 (or the prior month if your birthday is on the first). [3] If you are not receiving those benefits, you must sign up. TRICARE advises you to enroll in Part B during your Medicare Initial Enrollment Period, and no later than two months before you turn 65, so a late Part B start date does not open a break in TRICARE. [3] TRICARE also tells retirees to sign up when first eligible to avoid a Part B late-enrollment surcharge. [3] Families who want that penalty math can read our note on the Medicare Part B late enrollment penalty.

Who pays first

Medicare.gov puts the order this way: if you are on active duty, TRICARE pays first for Medicare-covered services and Medicare pays second. If you are not on active duty, Medicare pays first and TRICARE may pay second. If you get care at a military hospital or clinic, or any other federal health care provider, TRICARE pays, and Medicare usually does not. [1]

Retired households in the Piedmont almost always fall in the second line. TRICARE says Medicare is the primary payer, and TRICARE pays second to Medicare, or last if you have other health insurance. [2][10] In a typical civilian visit in North Carolina, the provider files with Medicare. Medicare pays its share and forwards the claim to the TFL contractor. You usually do not file a paper claim when Medicare and TFL are your only coverage. [2][5]

Other health insurance changes the order. If you have a Medicare supplement (or similar coverage not based on current work), Medicare pays first, the other plan pays second, and TRICARE pays last, and you file a paper claim with the TFL contractor. If you have current-employer coverage at an employer with more than 20 employees, the employer plan pays first, Medicare second, and TRICARE last. If you have Medicaid, Medicare pays first, TRICARE second, and Medicaid last. [11]

If you still have group coverage from a current job, that is a different calendar from TFL. Our working-past-65 Medicare and employer coverage article covers that path. The TFL-specific point is this: if you delay Part B while you keep employer coverage, you will not be covered by TFL during that delay, and TRICARE will not act as a second payer to the employer plan. [3]

Overseas care is another exception. Medicare covers the United States and U.S. territories. It does not pay in other overseas locations. When you use TFL overseas, TRICARE is the primary payer, and you owe TRICARE's deductible and cost-shares. You still must have Part B to remain TRICARE-eligible, even though Medicare is not paying abroad. [2]

What you pay when both programs cover the visit

For a service that both Medicare and TRICARE cover, Medicare pays the Medicare-approved amount, TRICARE pays the remaining amount, and you pay $0. [5][9] TRICARE also pays the Medicare Part A and Part B deductibles when both programs cover the services you receive. [12]

For 2026, Medicare lists a Part A inpatient hospital deductible of $1,736 per benefit period and a Part B deductible of $283 per year. After the Part B deductible, Original Medicare usually leaves 20% coinsurance on many doctor and outpatient services. [7] When both Medicare and TFL cover the visit, TFL is designed to pick up that remainder. [5][12] You can still have costs if only one program covers the service, or if neither does. [5][9] Dental and routine vision are not part of TFL. TRICARE points people who want those benefits to the Federal Employees Dental and Vision Insurance Program (FEDVIP). [5]

Some families ask whether they still want a Medicare Supplement (Medigap) policy once TFL is in place. TRICARE describes Medigap as optional, and it describes TFL as wraparound coverage that pays Original Medicare out-of-pocket costs for services covered by both Medicare and TRICARE. [10] If you enroll in a Medicare Advantage plan instead, TRICARE notes that you may pay copayments at the time of service, that TRICARE can reimburse copayments for TFL-covered services, and that you may need to file those claims yourself. [10]

How pharmacy works with TFL

TFL includes prescription coverage through the TRICARE Pharmacy Program. You do not need a Medicare Part D plan in order to have drug coverage. [10][13] Medicare says the same: if you have TRICARE, you do not need to join a Medicare drug plan. If you do join one, the Medicare drug plan pays first and TRICARE pays second. [1]

TRICARE's pharmacy benefit is creditable coverage (drug coverage expected to pay, on average, at least as much as Medicare drug coverage). [13][14] Keeping it in force helps you avoid a gap of 63 days or more without creditable coverage, which is the window Medicare uses for a Part D late-enrollment penalty. [10][14]

You can fill prescriptions at a military pharmacy, through TRICARE Pharmacy Home Delivery, or at a TRICARE retail network pharmacy. Copayments depend on the drug tier and where you fill. For calendar years 2026 and 2027, TRICARE lists these costs for most beneficiaries other than medically retired sponsors and certain survivors (those groups have a separate, frozen schedule): [15]

• Military pharmacy, up to a 90-day supply: $0 for generic formulary and brand-name formulary drugs.
• Home delivery, up to a 90-day supply: $14 generic formulary, $44 brand-name formulary, $85 non-formulary.
• TRICARE retail network pharmacy, up to a 30-day supply: $16 generic formulary, $48 brand-name formulary, $85 non-formulary.

Non-formulary drugs are generally not available at a military pharmacy without medical necessity. At a non-network retail pharmacy in the United States, costs are higher after the annual deductible. [15]

Part B is the switch for civilian pharmacy. TRICARE states that Medicare-eligible people who turned 65 on or after April 1, 2001, must have Part B. If you do not enroll in Part B, you can only get prescriptions filled at military pharmacies. [13]

What happens if Part B is delayed

Delaying Part B is the TFL mistake we see most often, usually because someone assumed TRICARE would keep paying the way it did before age 65.

If you delay Part B, you are not covered by TFL. [3] For a retired service member or a retiree's family member age 65 or older, Part A without Part B means you are not TRICARE-eligible at all. [6] Without Part B you also lose ordinary TRICARE pharmacy access and are limited to military pharmacies. [13] If you are not already drawing Social Security and you enroll later than two months before you turn 65, your Part B effective date will be delayed and you will have a break in TRICARE coverage. [3]

Employer coverage does not fill that TFL gap. Medicare may allow a Special Enrollment Period for Part B while you or a spouse has group health plan coverage based on current work. That can help you avoid a Part B penalty later. It does not keep TFL in force in the meantime, and TRICARE will not act as a second payer to the employer plan. [3] Once Part A and Part B are both in effect again, TFL is automatic for people who remain TRICARE-eligible in DEERS. [2][4]

VA health care is a separate system

Many North Carolina veterans have VA health care, Medicare, and TFL. Those programs do not merge into one bill.

Medicare.gov says that if you can get both Medicare and Veterans' benefits, you can get treatment under either program, and that Medicare and the VA generally cannot pay for the same items or services. Each time you get care, you choose which benefit to use. Medicare pays for Medicare-covered items and services. The VA pays for VA-authorized items or services in a VA or non-VA facility. [1]

The Department of Veterans Affairs says you can use VA health care along with Medicare, Medicaid, or TRICARE, and that other insurance does not change the VA benefits you can get. If you have both VA health care and Medicare, you choose which benefits to use each time you receive care, at a VA location or at a non-VA setting the VA has pre-authorized. [16] VA encourages veterans who already have VA health care to sign up for Medicare at 65, and it advises against dropping Medicare or TRICARE. VA does not normally cover family members, so a spouse's TFL and Medicare still matter even when the veteran uses VA care. [16]

Tell both your VA clinician and your Medicare providers what else you have. Mixing the two systems on the same visit is how duplicate bills start.

Practical takeaways

• TFL is automatic wraparound coverage once you are TRICARE-eligible in DEERS and have Medicare Part A and Part B. There is no TFL enrollment fee and no extra TFL card. [2][4]
• Each person needs their own Part A and Part B. At 65, Part A only means you are not TRICARE-eligible. [2][6]
• You must keep Part B, even overseas. Skipping it, dropping it, or missing premium payments ends TRICARE, including ordinary pharmacy access. [3][13]
• When you are not on active duty, Medicare pays first and TFL pays second. For care covered by both, you generally pay $0, including the Medicare deductibles. [1][5][12]
• The 2026 standard Part B premium is $202.90 a month (or higher by income). That is the ongoing cost of keeping TFL. [7][8]
• Pharmacy runs through TRICARE. You do not need Part D. If you add Part D, it pays first and TRICARE pays second. For 2026 and 2027, most TFL households pay $0 at a military pharmacy, $14/$44/$85 for a 90-day home-delivery fill, and $16/$48/$85 for a 30-day network retail fill. [1][13][15]
• If you delay Part B, TFL does not run in the background, and TRICARE will not second-pay an employer plan during that delay. [3]
• VA health care does not replace TFL. Choose VA or Medicare/TFL at each visit. [1][16]
• Confirm DEERS and each person's Part A and Part B dates, show both cards at civilian offices, and call the TFL contractor (WPS, 866-773-0404) if a claim does not cross over. North Carolina SHIIP offers free Medicare counseling at 1-855-408-1212. [2][4][17]
