Out-of-Pocket Costs
What you actually pay yourself — premiums, deductibles, coinsurance, and copays — after insurance.
Also known as: OOP, patient responsibility
Quick answer
Out-of-pocket (OOP) costs include every dollar you pay personally for healthcare: the Part B premium, any Part D premium, deductibles, coinsurance, copays, and costs for non-covered services. TFL eliminates the cost-sharing portion of OOP for dual-covered care, but does not reimburse premiums.
Why it matters
Understanding OOP is the only honest way to compare Original Medicare + TFL against Medicare Advantage + TFL. Most retirees discover their true OOP on Original Medicare + TFL is just the Part B premium.
Why this matters at age 65
MTF care had near-zero OOP. After 65, OOP shifts to a predictable monthly premium plus essentially $0 in cost-sharing — but only if you understand the moving parts.
When you'll encounter it
Annual budget planning, MA-vs-Original Medicare comparisons, IRMAA appeals.
Impact on Medicare
Premiums + deductibles + coinsurance = your gross OOP exposure.
Impact on TRICARE For Life
TFL zeroes out the cost-sharing portion for services covered by both — leaving premiums as your main remaining OOP.
Impact on Medicare Advantage
MA plans bundle costs differently — lower premium, but copays and the MOOP determine your real exposure.
Common misconceptions
- "TFL pays my Part B premium." — No — premiums are your responsibility (or IRMAA-adjusted by income).
Common mistakes to avoid
- Comparing MA plans on premium alone instead of full OOP.
- Forgetting Part D and IRMAA when budgeting.
Real-world scenario: A married retiree with $120K MAGI estimates 2026 OOP.
Part B premium + IRMAA + Part D premium ≈ $260/month total. Cost-shares on dual-covered care = $0. Annual OOP ≈ $3,120 + occasional non-covered services.
What should I do?
- 1Budget for Part B premium + any Part D premium + dental/vision out-of-plan costs.
- 2Compare MA plan total OOP (premium + copays + MOOP) against Original Medicare + TFL.
- 3If retiring soon, file Form SSA-44 to reduce IRMAA based on income drop.

- 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.
- I just retired and my income dropped. Can I lower my IRMAA?Yes. File SSA Form SSA-44 and provide proof of a 'life-changing event' (retirement, work stoppage, divorce, death of spouse, loss of pension, employer settlement).
- 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.
- Are my Medicare premiums tax-deductible?Generally yes, as a medical expense if you itemize and your total medical costs exceed 7.5% of AGI. Self-employed retirees may deduct premiums above the line. Talk to a tax professional.
- 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.
