What Does Medicare Pay For? Coverage Breakdown

Overview of Medicare Coverage

Medicare is the federal health insurance program designed to support Americans who are age 65 and older, certain younger individuals with disabilities, and people diagnosed with end-stage renal disease. The backbone of Medicare coverage is comprised of two main components: Medicare Part A (hospital insurance) and Medicare Part B (medical insurance). These two parts work together to provide coverage for inpatient hospital services, outpatient care, physician services, home health services, and preventive care. However, understanding the costs, covered services, and what Medicare does not cover is crucial for beneficiaries and caregivers when planning for health care expenses.

Also, it is important to know how Medicare interacts with other forms of coverage, such as Medicaid, as well as what effect other insurances or settlements may have, discussed further in resources like Medicare Lien explanations.

Medicare Part A: Hospital Insurance

What Medicare Part A Covers

Medicare Part A is widely referred to as hospital insurance because it primarily covers the costs associated with hospital stays, skilled nursing facility care, specific home health care, and hospice care. Here’s a breakdown of key services included under Part A in 2026:

• Inpatient hospital care: Includes semi-private rooms, food, general nursing, medications for inpatient treatments, and other hospital services. Coverage also extends to inpatient mental health care in psychiatric hospitals (with a maximum of 190 lifetime days), as well as rehabilitation facilities.
• Skilled nursing facility care: Coverage encompasses semi-private rooms, meals, skilled nursing services, therapies (physical, occupational, speech-language), necessary medical supplies and equipment, and medications provided within the facility. This is typically available following a qualifying three-day hospital stay.
• Hospice care: For beneficiaries with terminal illness and life expectancy of six months or less, Part A provides full support: pain management, medications, counseling for the patient and family, and short-term respite care for primary caregivers.
• Home health services: Includes part-time skilled nursing and home health aide services, occupational, physical, and speech-language therapy, and medical social services for individuals who are homebound and need intermittent skilled care.

What Medicare Part A Does Not Cover

Understanding services not covered by Medicare Part A helps avoid unexpected expenses. Part A does not cover private rooms (unless medically necessary), private-duty nursing, personal or comfort items (like TV or phone), round-the-clock in-home care, meal delivery, homemaker services unrelated to treatment, or general custodial care if no skilled nursing is needed.

Part A Costs for 2026

• Premium: Most (about 99%) Medicare beneficiaries pay no premium for Part A, as long as they or their spouse have at least 40 quarters (10 years) of Medicare-covered employment. Otherwise, the 2026 premium is $311 per month (with 30-39 quarters) or $565 (with fewer than 30 quarters).
• Deductible: $1,736 per benefit period-this must be paid before coverage begins for inpatient hospital care.
• Coinsurance for hospital stays:
  • Days 1-60: $0 per day (after deductible met)
  • Days 61-90: $434 per day
  • Days 91 and beyond: $868 per day (for up to 60 lifetime reserve days)
• Skilled nursing facility Coinsurance: Days 1-20: $0; Days 21-100: $217 per day

It’s clear that Medicare does not pay 100% of hospital or skilled nursing costs. Beneficiaries are responsible for certain out-of-pocket costs unless they have additional coverage like a supplemental policy. Those interested in policy options to cover these gaps may also consider Medicare Part C (Medicare Advantage) plans or Medicare Part F supplemental plans if eligible.

Medicare Part B: Medical Insurance

What Medicare Part B Covers

Medicare Part B is known as medical insurance and helps manage outpatient care costs and a wide range of services:

• Physicians’ services: Including visits to family doctors, specialists, and certain telehealth appointments.
• Outpatient care: Such as same-day surgery, observation, X-rays, and laboratory tests performed at a hospital or doctor’s office.
• Preventive services: Annual wellness visits, vaccinations (including flu and COVID-19 shots), cancer screenings, and cardiovascular screenings.
• Durable medical equipment (DME): Includes wheelchairs, walkers, hospital beds, blood sugar monitors, and oxygen equipment, when prescribed by a doctor.
• Some home health services: For individuals who qualify medically for intermittent skilled nursing care or therapy.
• Ambulance services: Emergency and, in some cases, non-emergency transportation to medical facilities.

For a full picture of costs and additional coverage options, beneficiaries should explore dedicated topics such as the details in Medicare Part F Coverage for gaps and supplemental coverage information.

Part B Costs for 2026

• Standard monthly premium: $202.90 (up from $185.00 in 2025). High-income enrollees may pay more based on income-related monthly adjustment amounts (IRMAA).
• Annual deductible: $283 (increased from $257 in 2025).
• Coinsurance: After you meet the Part B deductible, you typically pay 20% of the Medicare-approved amount for covered services.
• Immunosuppressive drug premium: For certain transplant recipients, the standard monthly premium for immunosuppressive drugs is $121.60 in 2026.

Note that some screenings, flu shots, and preventive services are covered in full by Medicare Part B when performed by a provider who accepts assignment.

Costs Associated with Medicare Parts A & B

When it comes to understanding the total cost of Medicare coverage, it’s important to factor in various elements:

• Premiums: Some beneficiaries pay a monthly premium for Part A (most do not), but all with Part B pay the standard or income-adjusted monthly premium.
• Deductibles: Both Part A and Part B charge annual or per-period deductibles which must be met before Medicare begins paying its share.
• Coinsurance and copayments: For many services, you are responsible for a percentage or fixed dollar amount of the Medicare-approved charge after meeting the deductible.
• Out-of-pocket maximums: Original Medicare does not have a set cap on how much you might spend in one year; this is a key reason many people consider Medicare Advantage or Medigap supplemental plans.

Beneficiaries interested in expanding or capping their Medicare spending often consider Medicare Advantage (Part C) plans. 2026 providers and plan options are discussed in detail at Who Offers Medicare Advantage Plans? 2026 Providers List.

What Original Medicare Does Not Cover

Despite the comprehensive nature of Parts A and B, there are several services not covered by Medicare that can leave significant coverage gaps:

• Prescription drug coverage: Original Medicare does not cover most outpatient prescription drugs. To obtain this coverage, beneficiaries must enroll in Part D standalone prescription drug plans or through Medicare Advantage plans that include drug coverage.
• Dental, vision, and hearing care: Routine dental exams, cleanings, fillings, dentures, vision exams/glasses, and hearing aids are excluded.
• Long-term care: Custodial care in a nursing home or assisted living, if that is the only care needed, is not covered. Medicare will only pay for skilled nursing care after certain hospitalizations and only for a limited period.
• Routine foot care: Including most regular podiatrist visits, unless related to a covered medical condition (like diabetic neuropathy).
• Personal or custodial care: Bathing, dressing, and other activities of daily living (if not associated with skilled medical needs), are not covered unless as part of a broader care plan under hospice or during covered home health.
• International coverage: Medical care outside the United States is largely not covered, with very limited exceptions.

Given these exclusions, many beneficiaries opt for policies that supplement Original Medicare, such as Medicare Supplement (Medigap) policies or Medicare Part C plans, which may include extra benefits like dental, vision, or hearing coverage. For those who want a blanket supplement, understanding Medicare Part F Coverage can be crucial, while for managing prescription costs, exploring Part D plans is essential.

Frequently Asked Questions about Medicare Coverage

How do I know if my service is covered by Medicare?

Generally, if a service is medically necessary and ordered by a Medicare-enrolled provider, and falls under Part A or Part B criteria, it will be covered. Preventive services are often fully covered, whereas other services (like outpatient tests) are subject to cost-sharing. For guidance on complex situations, see how settlement claims and liens may impact coverage at What Is a Medicare Lien? Personal Injury Settlement Facts.

Is there an out-of-pocket maximum for Original Medicare?

No, Original Medicare (Parts A & B) does not have a yearly out-of-pocket spending cap. That’s why many people purchase supplemental insurance or a Medicare Advantage plan, which does have an annual maximum.

How do I get help with my out-of-pocket Medicare costs?

Depending on income and assets, some individuals qualify for Medicaid, Medicare Savings Programs, or Extra Help for prescription coverage. Supplemental policies like Medigap or coverage through Medicare Part C can provide peace of mind and help cover deductibles and coinsurance. For a deeper look at how various plans work together, see Who Pays First: Medicare or Medicaid? Payer Rules Explained.

How do I get prescription drug coverage?

Prescription drugs are not included in Original Medicare. Most people add prescription coverage by enrolling in a separate Part D plan or choosing a Medicare Advantage plan with prescription drug benefits.

Can I use Medicare outside of the United States?

With few exceptions, Medicare does not pay for care outside the U.S. You may wish to explore travel medical insurance or Medicare supplement plans with limited foreign emergency coverage if you travel abroad frequently.

If I choose a Medicare Advantage Plan (Part C), am I still covered for everything above?

Medicare Advantage plans are run by private insurers and must cover all benefits offered by Part A and Part B, often with additional benefits. Some may include dental, vision, or prescription drug coverage not present in Original Medicare.
