- Benefit Period (Part A)The Part A timeframe used to measure hospital deductibles and coinsurance — it resets after 60 days out of the hospital.
- VA HealthcareA separate federal healthcare system run by the Veterans Health Administration for enrolled veterans — it does not coordinate with Medicare or TRICARE For Life.

FAQs26
- How much does Medicare Part B cost?Most people pay the standard Part B premium (roughly $185/month in 2026). Higher-income retirees pay IRMAA on top. Lower-income retirees may qualify for help paying it.
- Do I really need Medicare Part B?Yes. Without Part B, you lose TRICARE For Life. There is no workaround.
- How do I lower my Part B premium?Two main paths: enroll in a Medicare Advantage plan with a Part B giveback, or — if your income has dropped — appeal an IRMAA surcharge with SSA Form SSA-44.
- Why is my Part B premium so high?Probably IRMAA — an income-based surcharge SSA applies based on your tax return from two years ago. It can be appealed if your income has dropped.
- Can I delay Part B if I'm still working?Only if you (or your spouse) have employer group health coverage based on current employment. TRICARE does not qualify.
- What if I can't afford the Part B premium?Look into a Medicare Advantage plan with a Part B giveback, the Medicare Savings Program if income is low, or Extra Help. Do NOT drop Part B.
- I'm still working past 65. Can I delay Part B?Only if you have true employer group health coverage from active employment (yours or your spouse's, 20+ employees). In that case you get a Special Enrollment Period later. But TFL won't activate until you take Part B.
- Can I get a Part B giveback and keep TRICARE For Life?Yes. Enrolling in a Medicare Advantage plan with a Part B giveback lowers your premium, and TFL stays intact as a wraparound for in-network MA care.
- 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.
- Can I take Part A now and add Part B later?You can — but for TFL purposes, that's the same as not enrolling. TFL requires both A and B simultaneously. Without B, TFL is suspended.
- How do I pay the Part B premium?If you draw Social Security or DFAS retired pay, the premium is automatically deducted. If not, Medicare bills you quarterly via Medicare Easy Pay or direct billing.
- Can my state help pay my Part B premium?If your income is low enough, yes. Medicare Savings Programs (QMB, SLMB, QI) pay the Part B premium for qualifying beneficiaries. Apply through your state Medicaid office.
- Why did one extra dollar of income raise my Part B premium hundreds of dollars?IRMAA uses cliff thresholds, not gradual tiers. Crossing a bracket by even $1 jumps you to the next premium amount for the entire year.
- Does TFL pay my Part B premium?No. TFL doesn't pay any Medicare premiums. The Part B premium is your responsibility. A Medicare Advantage Part B giveback can refund part of it while TFL remains intact.
- 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.
- What is a Part B premium giveback?An MA plan benefit that returns part of your Part B premium to your Social Security check — typically $50–$170/month, depending on plan and ZIP.
- Doesn't VA healthcare replace my need for Medicare Part B?No. VA does not satisfy the Medicare Part B requirement for TFL, and VA does not pay for civilian care unless authorized through Community Care. Skipping Part B costs you TFL.
- Part B Costs & IRMAA — FAQ categoryMedicare Part B isn't free, and higher-income retirees pay IRMAA on top of the standard premium. These FAQs explain what you'll actually pay — and how a Part B giveback can lower it.
- Do I need Medicare Part A if I have TRICARE?Yes. TFL requires Part A and Part B. Part A is typically premium-free if you or your spouse worked 40+ quarters paying Medicare taxes.
- 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.
- 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.
- Should I enroll in Medicare Part D?No, for almost every TFL beneficiary. TRICARE Pharmacy (Express Scripts) is creditable coverage and cheaper than most Part D plans. Adding Part D usually costs more without adding benefit.
- 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.
- Will I lose TRICARE For Life if I join Medicare Advantage?No. As long as you keep Medicare Part B, TFL stays. Inside an MA plan, MA becomes primary and TFL becomes a secondary wraparound for in-network MA cost-shares.
- Can I still use the VA after I have Medicare and TFL?Yes. VA is a separate system. Using VA doesn't end Medicare or TFL, and TFL doesn't pay VA bills. Many veterans use all three — VA for service-connected care, Medicare + TFL for civilian care.
- 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.
