TRICARE For Life & Medicare
TRICARE For Life is built on Medicare. It does not replace it, it wraps around it — which is why Part B is not optional here, and why the honest answer for a lot of TFL members is that they already have better coverage than anything an agent can sell them.
No plan described here is a veterans plan, a VA plan, a military plan or a federal employee plan. Medicare Advantage and Part D plans are private insurance. None is issued by, sponsored by, endorsed by or affiliated with the Department of Veterans Affairs, the Department of Defense, any branch of the armed services, or the Office of Personnel Management. Your VA, TRICARE, CHAMPVA, FEHB or PSHB coverage is administered by those agencies and nothing on this page changes it.
TRICARE For Life & Medicare, step by step
TRICARE For Life is not something most veterans have
It is for Medicare-eligible uniformed services retirees, their eligible family members and certain survivors — tied to retirement from uniformed service, typically twenty or more years or a medical retirement. Serving does not by itself make somebody TFL-eligible, and this gets assumed both ways. Check DEERS rather than guessing.

There is no TFL premium. The cost of TFL is your Part B premium
TFL activates automatically once you have Medicare Part A and Part B and are correctly listed in DEERS. There is no enrolment form to file and no separate premium to pay. What you pay is the Medicare Part B premium, and that is what keeps the whole arrangement running.

Part B is mandatory, and this is the absolute in this section
A TFL beneficiary who drops Part B loses TRICARE For Life. Not reduced, not degraded — lost. There is no version of a Medicare conversation where dropping Part B is the right move for somebody on TFL, and anyone who suggests it is telling you something that will cost you your coverage.

How the two pay together
For services covered by both Medicare and TRICARE, Medicare pays first and TFL pays the remaining Medicare cost share — out-of-pocket cost is typically near zero. For services TRICARE covers but Medicare does not, TFL pays first, subject to the TRICARE deductible and cost share. For services Medicare covers but TRICARE does not, you owe the Medicare cost share. The TRICARE pharmacy benefit is creditable drug coverage.

If you enrol in a Medicare Advantage plan, you do not lose TFL
This gets stated wrongly in both directions, so here it is plainly. You still have Medicare. The Medicare Advantage plan becomes the primary payer and TRICARE For Life remains the second payer for TRICARE-covered services. One practical note: TRICARE's published guidance says Medicare Advantage claims do not cross over automatically, so a claim may occasionally need chasing. In practice providers bill both and members rarely do anything — but it is worth knowing the rule exists so you recognise it if it happens.

The trade-offs that actually decide it
TFL with Original Medicare has no network, no referral requirement and no prior authorisation — you may see any authorised provider. A Medicare Advantage plan introduces all three. TFL coverage is available worldwide; Medicare Advantage plans carry a defined service area, which matters if you travel, spend winters elsewhere or live abroad part of the year. And saving money on medical care is not the argument: TFL already produces near-zero out-of-pocket cost on services both programmes cover. Anyone pitching a plan to you on medical savings is selling something that is not there.

Where a plan can genuinely help
TFL does not include routine dental. If you have no dental coverage and a real need, a Medicare Advantage plan with a dental benefit addresses a gap that is actually open — and because your TRICARE pharmacy benefit is already creditable, the structure that fits is a plan with no Part D in it.

Where the drug coverage question lands
Every kind of coverage on this page already includes prescription drug coverage that Medicare counts as creditable — meaning it is at least as good as a Part D plan, so you are not building a late-enrollment penalty while you hold it. That one fact decides the shape of any Medicare Advantage plan that would make sense next to it.
A Medicare Advantage plan that carries no Part D drug coverage is usually written as “MA-Only” or a medical-only plan. It covers what Part A and Part B cover, plus whatever extras the plan includes, and it leaves your existing drug coverage alone. For two of the programmes below, that is not a preference — adding Part D takes a benefit away.

Talk it through with somebody who knows how these fit together
No medical questions, no pressure, and no application on the first call. If the honest answer is that your existing coverage already does the job, that is the answer you will get.
The ones that come up every week
Does enrolling in a Medicare Advantage plan affect my VA health care?
No. Your VA enrolment, your Priority Group and your disability compensation are administered by VA and are not changed by a private insurance enrolment. What a Medicare Advantage plan does is give you a way to get care outside the VA system. It pays nothing toward care you receive at a VA facility.
I use the VA for all my prescriptions. Do I need a Medicare drug plan?
Generally no. VA pharmacy benefits are creditable prescription drug coverage, which means you are not building a Part D late-enrolment penalty while you use them. The same is true of TRICARE, CHAMPVA and federal plan drug benefits. Confirm your own situation with the programme that administers your coverage.
Can I keep my FEHB plan and take a Medicare Advantage plan at the same time?
OPM states that an individual may enrol in a Medicare Advantage plan and also remain enrolled in an FEHB plan. If you do, OPM requires you to tell your FEHB plan, because it needs to know whether you have Original Medicare or a Medicare Advantage plan in order to coordinate benefits correctly. Confirm the specifics with your own carrier and with OPM at 1-888-767-6738.
What is the difference between suspending and cancelling FEHB or PSHB?
Suspension is reversible — an annuitant can return during a later Open Season, or immediately if a Medicare Advantage plan is involuntarily lost. Cancellation is generally permanent, and takes the government's share of the premium with it. They are different administrative actions. Before filing either, call OPM Retirement Services at 1-888-767-6738 and get the answer for your own enrolment.
I get my CHAMPVA medications in the mail. Should I take a Medicare drug plan?
VA states that Meds by Mail is available only to CHAMPVA beneficiaries with no other prescription coverage, and that you do not need Part D to get CHAMPVA. A Medicare drug plan would end Meds by Mail rather than add to it. Confirm with CHAMPVA at 1-800-733-8387 before changing anything.
Will a Medicare Advantage plan lower my Part B premium?
Some plans include a Part B premium reduction, often called a giveback. It is a feature of particular plans in particular counties rather than something Medicare Advantage does generally, and the amount varies. It is worth asking about for your own county, and worth checking on Medicare.gov rather than taking anyone's word for it — including ours.
Does TRICARE For Life end if I join a Medicare Advantage plan?
No. You still have Medicare, the Medicare Advantage plan becomes the primary payer, and TRICARE For Life remains the second payer for TRICARE-covered services. Note that TRICARE's guidance says Medicare Advantage claims do not cross over automatically, so a claim may occasionally need following up. Dropping Part B, on the other hand, does end TRICARE For Life.
