Enrollment basics

When should I enroll in Medicare?

During your Initial Enrollment Period — the 7-month window starting 3 months before your 65th-birthday month. Enroll in month 1 to guarantee Part B (and TFL) are active on day one of your 65th-birthday month. See Lesson 5.

How do I enroll in TFL?

You don't — TFL activates automatically when you have Medicare Parts A and B and your DEERS record is current. See Lesson 3.

Do I have to enroll in Part B if I have TFL?

Yes. Part B is required to maintain TFL. Drop Part B and TFL ends. See Lesson 2.

Costs

How much does this all cost?

Roughly the Part B premium (~$202.90/month in 2026) and nothing more for the typical retiree. Most office visits at participating providers cost $0. See Lesson 2.

Is there a TFL premium or enrollment fee?

No. TFL has $0 premium, $0 enrollment fee, and $0 deductible when Medicare is primary. See Lesson 3.

What if I can't afford the Part B premium?

Programs like Medicare Savings Programs and Extra Help exist for low-income beneficiaries. Contact your State Health Insurance Assistance Program (SHIP) or SSA to apply.

Providers and access

Will my MTF doctor still see me?

Maybe, on a space-available basis — you cannot count on it. Plan to use civilian Medicare-participating providers. See Lesson 8.

How do I find a civilian doctor?

Use medicare.gov/care-compare. Ask each provider, "Do you accept Medicare assignment?" See Lesson 9.

Do I need a referral for specialists?

No. Original Medicare + TFL has no referral requirement. See Lesson 9.

Prescriptions

Do I need Medicare Part D?

No. TRICARE Pharmacy (Express Scripts) is your drug coverage and is officially "creditable." Adding Part D usually causes problems. See Lesson 10.

Where do I fill prescriptions?

Four options: MTF pharmacy ($0), Express Scripts home delivery (lowest non-MTF cost), TRICARE retail network, or non-network (highest cost). See Lesson 10.

Family and survivors

Does my spouse get TFL automatically when I do?

No. Each spouse activates TFL independently when they personally turn 65 and enroll in Medicare A+B. See Lesson 3.

What happens when the sponsor dies?

A Medicare-eligible surviving spouse continues to have TFL as long as DEERS is current and Part B remains active. See Lesson 3.

Other coverages

Should I buy a Medigap plan?

No. TFL fills the Medigap role for you. Buying Medigap on top of TFL wastes money. See Lesson 5.

What about dental, vision, and hearing?

Not covered by Original Medicare or TFL. Options: FEDVIP through BENEFEDS, a Medicare Advantage plan that bundles these benefits, or paying out of pocket. VA may cover hearing aids for service-connected loss. See Lesson 11.

Should I consider Medicare Advantage?

Sometimes — but only after you fully understand Original Medicare + TFL. MA plans add bundled benefits but introduce networks, referrals, and prior authorization. See Lesson 13.

Coordination

How do Medicare, TFL, and VA work together?

They don't share claims — you choose which system to use for each visit. Keep all three active. See Lesson 12.

How does TFL handle care overseas?

TFL covers overseas care through the TRICARE Overseas Program, even though Medicare generally does not pay outside the U.S. See the TFL Handbook overseas chapter.

What if I have a claim problem?

Most claims crossover automatically. If a claim is wrong, call WPS at 1-866-773-0404 for TFL issues or 1-800-MEDICARE for Medicare-side issues. See Lesson 7.

The big takeaway

• Find a civilian Medicare-participating PCP.
• Use TRICARE Pharmacy (not Part D).
• Keep DEERS current.

FAQs

• Does TRICARE For Life work overseas?Yes. Overseas, TFL acts as your primary payer because Medicare generally doesn't pay outside the U.S. You'll usually pay the provider up front and file a paper claim with TFL overseas.
• What are the biggest mistakes retired military make at 65?Declining Part B, missing the IEP, ignoring DEERS, enrolling in Part D unnecessarily, and assuming MTF access continues. Each can cost thousands or end TFL.
• I live overseas full-time. How does Medicare + TFL work?Keep paying Part B to keep TFL. Use TFL as your primary payer overseas (Medicare doesn't pay abroad). File paper claims with International SOS.
• If I move overseas, can I drop Part B since Medicare doesn't pay there?Don't. Dropping Part B ends TFL the same day. Re-enrolling later triggers a permanent late penalty plus a coverage gap.
• Does TFL work on a cruise ship?Yes. TFL covers cruise-ship medical care under the overseas rules. Medicare covers narrow cruise-ship scenarios within 6 hours of a U.S. port.
• Can I drop Part B later to save money?Technically yes, but the day Part B ends, TFL ends. Re-enrolling requires waiting for the next General Enrollment Period and triggers a permanent late penalty.
