What Medicare Covers in 2026 — A Tax-Savvy Guide for Retirees & Self-Employed Americans
Medicare is more than health insurance — it’s a core part of retirement and tax planning.
What Medicare covers (and how much you pay) directly affects your medical costs, deductions, IRMAA surcharges, and even when you must stop HSA contributions.
This 2026 guide explains what Parts A, B, and D cover, what’s new for 2026, and how Medicare expenses interact with your U.S. tax return.
1️⃣ Medicare Part A — Hospital, Rehab & Hospice
Medicare Part A covers inpatient hospital stays, skilled nursing facility (SNF) care,
certain home health services, and hospice care.
Most Americans qualify for premium-free Part A after earning 40 quarters of work credits.
- Inpatient hospital care (room, meals, nursing, medications)
- Skilled nursing facility care (up to 100 days after a qualifying hospital stay)
- Hospice services for terminal illness
Daniel, a retired engineer, spent 12 days in a skilled nursing facility after surgery.
Because he had a qualifying hospital stay, Medicare Part A covered most facility charges.
His inpatient deductible may later count as a medical expense on Schedule A.
Part A does not cover long-term custodial care.
However, qualified out-of-pocket nursing home expenses may be deductible if you itemize.
2️⃣ Medicare Part B — Doctors, IRMAA & Outpatient Care
Medicare Part B covers outpatient medical services such as doctor visits,
diagnostic testing, durable medical equipment, and emergency outpatient care.
Unlike Part A, Part B always has a monthly premium.
- Physician and specialist visits
- Lab work, imaging, and diagnostics
- Physical, occupational, and speech therapy
- Durable medical equipment (CPAP, oxygen, wheelchairs)
Higher-income taxpayers may pay an Income-Related Monthly Adjustment Amount (IRMAA).
Your 2026 Part B premium is based on your 2024 tax return, not your current-year income.
A Roth conversion, capital gains, or business income in 2024 can increase Medicare premiums two years later.
Angela paid $1,000 for outpatient therapy.
Medicare covered 80%, leaving $200 out of pocket.
Her Part B premiums and copays may count toward deductible medical expenses.
Many retirees add Medigap (Supplement) policies to reduce Part B coinsurance.
These premiums are also considered medical expenses for tax purposes.
3️⃣ Medicare Part D — Prescription Drugs & 2026 Changes
Medicare Part D covers prescription medications.
This area has seen major changes due to the Inflation Reduction Act.
- Monthly Part D premiums (varies by plan and income)
- Deductibles, copays, and coinsurance for medications
- Annual out-of-pocket cap introduced starting 2025 and continuing into 2026
Part D premiums and prescription copays are deductible medical expenses.
Lower out-of-pocket drug costs may reduce your deduction —
but significantly improve cash flow for retirees.
4️⃣ Preventive Care & What’s New in 2026
Medicare continues to expand preventive coverage to reduce long-term health risks
and unexpected medical bills.
- Annual Wellness Visit and Welcome-to-Medicare exam
- Vaccines (flu, pneumonia, COVID-19)
- Cancer screenings
- CT colonography (virtual colonoscopy)
- Home blood-pressure monitoring programs
Linda, age 70, received a CT colonography fully covered by Medicare in 2026.
Avoiding a $400 bill reduced her total medical expenses —
but prevented unnecessary out-of-pocket costs.
5️⃣ Medicare Costs & Tax Deductions
| Category | Tax Treatment |
|---|---|
| Part B / Part D / Medigap premiums | Medical expense deduction (Schedule A) |
| Copays, deductibles, prescriptions | Medical expense deduction if AGI threshold met |
| Self-employed Medicare premiums | Above-the-line deduction (no itemizing required) |
| HSA contributions after Medicare | Not allowed — penalties apply |
Jose and Maria are self-employed and pay $5,400 in Medicare and Medigap premiums.
They deduct the full amount as self-employed health insurance,
even without itemizing deductions.
6️⃣ Key Takeaways & Next Steps
- Part A covers hospital and rehab — not long-term care.
- Part B premiums may increase due to IRMAA based on prior-year income.
- Part D changes significantly reduce prescription drug risk.
- Medicare premiums often have tax value.
- HSA contributions must stop before Medicare enrollment.
If your 2024 income was unusually high,
review whether you may fall into a higher IRMAA tier in 2026
and plan Roth conversions, capital gains, and business income accordingly.
