Part B Premium
The monthly premium for Medicare Part B — the single most important ongoing Medicare cost for TFL beneficiaries, since TFL requires Part B to remain active.
Also known as: Medicare Part B premium, Standard Part B premium
Quick answer
Every Medicare Part B enrollee pays a monthly premium. The standard premium in 2026 is $185.00/month (subject to annual CMS adjustment). Higher-income beneficiaries pay IRMAA on top. The premium is deducted from Social Security checks if you're receiving benefits; otherwise it's billed quarterly via Medicare invoice or Medicare Easy Pay.
Why it matters
For TFL beneficiaries, the Part B premium is the price of keeping TRICARE For Life active. The premium is non-negotiable — letting it lapse terminates Part B immediately, which in turn terminates TFL.
Why this matters at age 65
Many retirees experience sticker shock when they see Part B premium deducted from their first Social Security check. Plan ahead: $185/month (or more with IRMAA) is a fixed retirement expense that funds the TFL safety net. A veteran-focused MA plan can offset $50-$175 of this premium via a Part B giveback.
When you'll encounter it
Monthly — deducted from your Social Security check or billed via Medicare invoice. Premium adjustments take effect each January.
Impact on Medicare
Pays for your Part B coverage (doctor visits, outpatient, DME, preventive care). Late payment triggers eventual termination of Part B.
Impact on TRICARE For Life
TFL is contingent on the Part B premium being paid. The day Part B terminates for non-payment is the day TFL terminates.
Impact on Medicare Advantage
MA plans don't replace the Part B premium — you continue paying it to Medicare. But many veteran-focused MA plans offer a 'Part B giveback' that reduces what's deducted from your SS check by $50-$175/month.
VA Healthcare considerations
Paying the Part B premium is what keeps TFL active even if you receive most care at the VA. Many veterans pay Part B specifically to maintain TFL as a backup for travel, emergencies, family care, and non-service-connected conditions.
Military-specific context
Compared to a single hospitalization, the annual Part B premium ($2,220 standard) is an enormous bargain — TFL routinely zeros out hospital cost-shares that would otherwise exceed $20,000.
Common misconceptions
- "TRICARE pays my Part B premium." — It does not. You pay the premium directly to Medicare.
- "If I have IRMAA, that's because something is wrong." — IRMAA is income-based and applies to roughly 7% of beneficiaries — it's standard, not a mistake.
- "I can pause Part B and resume later without consequence." — Dropping Part B terminates TFL and triggers permanent late penalties when you re-enroll.
Common mistakes to avoid
- Missing quarterly Part B invoices when delaying Social Security — set up Medicare Easy Pay to auto-debit.
- Cancelling Part B to save money in retirement — terminates TFL with no recovery.
- Not budgeting for IRMAA in the year after retirement.
Real-world scenario: A retired Marine pays the standard Part B premium and is hospitalized for 6 days after a stroke.
Medicare pays its 80% on outpatient services and the Part A hospital portion. TFL pays virtually all remaining cost-shares as secondary. Total out-of-pocket: roughly $0 against a $48,000 hospital bill. Annual Part B premium: $2,220 — paid back many times over in a single hospitalization.
What should I do?
- 1Budget the Part B premium (plus any IRMAA) as a fixed retirement expense.
- 2Set up Medicare Easy Pay if you're not yet receiving Social Security — avoids missed quarterly invoices.
- 3If money is tight, evaluate veteran-focused MA plans with Part B giveback BEFORE cancelling Part B.
- 4If income has dropped, file SSA-44 to reduce IRMAA — but never let Part B lapse.

- Creditable CoverageNon-Medicare coverage that CMS deems at least as good as a standard Medicare Part D plan — TRICARE Pharmacy qualifies, so TFL beneficiaries don't need Part D.

- 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.
- 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.
- 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.
