Quick Answer: Medicare covers a wide range of medical services—hospital stays, doctor visits, lab work, and prescription drugs—but has notable gaps including most dental care, hearing aids, and long-term custodial care. The answer almost always depends on which part of Medicare you have and whether the service is medically necessary.

One of the most common questions among adults 65 and older is simply, does Medicare cover this? Whether you’re facing a medical procedure, shopping for prescription drugs, or planning for a potential nursing home stay, the answer shapes real financial decisions.
This guide gives you a plain-English breakdown of what Medicare pays for—and crucially, what it does not—so you can avoid surprise bills and make smarter enrollment choices.
1. Understanding the Four Parts of Medicare
Medicare is not a single insurance policy. It is a federal health insurance program divided into four parts, each covering a different category of care.
| Part | What It Covers | Who Pays the Premium |
|---|---|---|
| Part A | Hospital stays, skilled nursing facility care, hospice, and some home health care | Most enrollees pay $0 (if you worked 40+ quarters) |
| Part B | Doctor visits, outpatient services, preventive care, and some home health care | You pay $202.90/month (standard 2026 rate) |
| Part C | Everything in Parts A + B, sold by private insurers and often including dental, vision, and hearing | Plan-specific; many $0-premium plans exist |
| Part D | Prescription drug coverage | Plan-specific; average ~$39/month in 2025 |
When people ask, “Does Medicare cover” a particular service, the answer usually hinges on which Part applies—and whether the service meets Medicare’s definition of “medically necessary.”
2. What Medicare Covers: The Full List
Hospital Care (Part A)
Medicare Part A covers inpatient hospital care after you meet the annual deductible of $1,736 (2026). This includes a semi-private room, meals, nursing care, and most medications administered during your stay. For the first 60 days, you pay no coinsurance. Days 61 through 90 cost $434 per day. After 90 days, you draw from a 60-day lifetime reserve, costing $868 per day.
Skilled Nursing Facility (SNF) Care (Part A)
If you’ve had a qualifying 3-day hospital inpatient stay, Medicare Part A covers up to 100 days in a skilled nursing facility. Days 1 through 20 are fully covered. Days 21 through 100 require a $217 per day copay. After day 100, Medicare pays nothing — this is when families must turn to Medicaid or personal funds.
Doctor Visits and Outpatient Services (Part B)
Medicare Part B covers 80% of approved costs for doctor visits after your $283 annual deductible (2026). You owe the remaining 20% with no out-of-pocket cap (unless you have Medigap). This 20% coinsurance can add up quickly for major procedures.
Preventive Care (Part B — Often 100% Covered)
One of Medicare’s best-kept secrets is its preventive care coverage. Many preventive services are covered at 100% with no deductible, including:
- Annual Wellness Visit
- Cardiovascular disease screenings
- Colorectal cancer screenings (colonoscopy)
- Diabetes screenings
- Bone mass measurements (osteoporosis screening)
- Flu, pneumococcal, and COVID-19 vaccines
- Mammograms (screening, once per year)
- Depression screenings
Prescription Drugs (Part D)
Medicare Part D covers a formulary (list) of prescription drugs chosen by your specific plan. The biggest 2025 change: a new $2,100 annual out-of-pocket cap on Part D costs, the result of the Inflation Reduction Act. This is a major financial protection for seniors on expensive medications.
Home Health Care (Parts A and B)
Medicare covers medically necessary home health care if you are homebound and a doctor certifies the need. Covered services include skilled nursing care, physical therapy, speech-language pathology, occupational therapy, and home health aide services. There is no deductible for home health services, and there is no limit on the number of covered visits—as long as your doctor recertifies the need.
Mental Health Services (Part B)
Medicare Part B covers outpatient mental health services, including visits with a psychiatrist, psychologist, or licensed clinical social worker. Medicare pays 80% after the deductible. Inpatient psychiatric hospital care is covered under Part A, with a 190-day lifetime limit.
Durable Medical Equipment (Part B)
Medicare Part B covers durable medical equipment (DME) that is medically necessary and ordered by a doctor. This includes wheelchairs, walkers, hospital beds for home use, oxygen equipment, and continuous positive airway pressure (CPAP) machines. You typically pay 20% coinsurance after the Part B deductible.
3. What Medicare Does NOT Cover
This list surprises many beneficiaries—and the gaps are expensive.
| Service | Original Medicare Coverage | Possible Alternative |
|---|---|---|
| Routine dental care | Not covered | Medicare Advantage, standalone dental plan |
| Dentures | Not covered | Medicare Advantage, dental savings plan |
| Hearing aids | Not covered | Medicare Advantage, OTC hearing aids |
| Routine vision/eyeglasses | Not covered | Medicare Advantage, VSP, AARP discount plans |
| Long-term custodial care | Not covered | Long-term care insurance, Medicaid |
| Overseas medical care | Generally not covered | Medigap Plans C, D, F, G, M, N, travel insurance |
| Cosmetic surgery | Not covered | Out of pocket |
| Routine foot care | Partial (only if medically necessary) | Medicare Advantage |
| Acupuncture | Covered only for chronic low back pain (Part B) | Medicare Advantage |
4. What You Pay Out of Pocket in 2026
Even for services Medicare does cover, you share the cost. Here are the key 2026 cost-sharing numbers to know:
| Cost | 2026 Amount |
|---|---|
| Part A deductible (per benefit period) | $1,736 |
| Part B deductible (annual) | $283 |
| Part B standard monthly premium | $185 |
| Part B coinsurance (after deductible) | 20% of approved amount |
| Part D out-of-pocket cap (new in 2025) | $2,100 |
| SNF coinsurance (days 21–100) | $217/day |
There is no out-of-pocket maximum for Original Medicare Parts A and B combined—meaning a catastrophic illness could result in unlimited cost-sharing. Medigap (Medicare Supplement) plans exist specifically to cap these costs.
5. How Medicare Advantage Changes Coverage
Medicare Advantage (Part C) plans are sold by private insurers and must cover everything Original Medicare covers, but they typically add significant extras. These commonly include dental, vision, hearing aids, fitness memberships, and over-the-counter allowances. As of 2025, approximately 51% of all Medicare beneficiaries are enrolled in a Medicare Advantage plan.
The trade-off: Advantage plans use provider networks. You may need prior authorization for certain services, and your in-network doctors may be more limited than with Original Medicare.
