Does Original Medicare pay the full hospital bill?
Original Medicare helps pay for covered hospital care, but it usually does not pay the entire bill. For inpatient hospital care, Medicare Part A covers many hospital services after you meet the Part A deductible. For doctor services you receive while in the hospital, Medicare Part B may apply.
Important: Your hospital bill can include more than one type of charge. A stay may involve Part A hospital facility costs, Part B doctor charges, outpatient services, drugs, and items Medicare may not cover.
What do you pay for inpatient hospital care in 2026?
For covered inpatient hospital care under Original Medicare in 2026, your costs are based on a benefit period. A benefit period begins when you are admitted as an inpatient and ends after you have not received inpatient hospital care or skilled nursing facility care for 60 days in a row.
- Days 1 to 60: You pay the 2026 Part A deductible of $1,736, then $0 coinsurance per day.
- Days 61 to 90: You pay $434 per day.
- Days 91 to 150: You pay $868 per day while using lifetime reserve days.
- After day 150: You pay all costs under Original Medicare.
Because the Part A deductible applies to each benefit period, it is possible to owe it more than once in a calendar year if you have separate hospital stays that start new benefit periods.
What hospital services does Part A cover?
Medicare Part A generally covers medically necessary inpatient hospital care when you are formally admitted to a hospital that accepts Medicare. Covered inpatient services can include semi-private rooms, meals, general nursing, certain drugs, and other hospital services and supplies that are part of your inpatient treatment.
Medicare does not cover every hospital-related expense. Examples of non-covered items may include private-duty nursing, a private room unless medically necessary, personal care items, and a television or phone in your room if there is a separate charge.
How do Part B and outpatient hospital costs affect your bill?
Medicare Part B may cover doctor services you receive while you are in the hospital. It also covers many outpatient hospital diagnostic and treatment services. After the Part B deductible applies, you generally pay 20 percent of the Medicare-approved amount for many Part B services.
Hospital status matters. Even if you stay overnight, you may be considered an outpatient if the hospital has not formally admitted you with a doctor’s order. Outpatient status can affect what you pay for services such as lab tests, X-rays, drugs, and observation services.
Can Medigap, Medicaid, or Medicare Advantage change your costs?
Yes. Other coverage can change what you owe.
- Medigap: Medicare Supplement Insurance can help pay certain Original Medicare cost-sharing amounts, such as coinsurance, copayments, and deductibles, depending on the plan.
- Medicaid or Medicare Savings Programs: If you qualify, state programs may help pay some Medicare premiums and cost-sharing amounts.
- Medicare Advantage: Medicare Advantage plans must cover Medicare Part A and Part B services, but plans can use different copayments, coinsurance, provider networks, and prior authorization rules.
If you have a Medicare Advantage plan, check your plan documents or contact the plan before a scheduled hospital service when possible.
What should you ask before or after a hospital stay?
To better understand your potential costs, ask the hospital or your doctor these questions:
- Am I being admitted as an inpatient, or am I under outpatient observation?
- Does the hospital accept Medicare?
- Which services are expected to be billed under Part A and which under Part B?
- Are any recommended services, drugs, or items not covered by Medicare?
- If I have Medicare Advantage, is this hospital in my plan network?
After the stay, review your Medicare Summary Notice or plan explanation of benefits to see what Medicare or your plan paid and what you may owe.
