Medicare Advantage covers hospital stays, doctor visits, and prescription drugs — usually with lower premiums than Original Medicare, but with network limits and higher out-of-pocket costs when you need care

Medicare Advantage (also called Part C) is an alternative to Original Medicare run by private insurance companies approved by Medicare. Instead of going to any doctor or hospital that accepts Medicare, you choose a plan and use doctors and hospitals in that plan's network. In exchange, your monthly premium is often lower than Original Medicare, and your prescription drugs are included in one bill instead of requiring a separate Part D plan.

The trade-off is real: you pay more when you use care — through copays, coinsurance, and deductibles — and you may need permission from your plan before seeing a specialist or getting certain treatments. Most Medicare Advantage plans also have an annual out-of-pocket maximum, which means once you spend a certain amount on copays and coinsurance in a year, the plan covers the rest. That maximum varies by plan and by year, but it protects you from unlimited costs.

Key Takeaways

  • Medicare Advantage includes hospital, doctor, and prescription drug coverage in one plan, with a monthly premium that is often lower than Original Medicare plus a separate drug plan.
  • You must use doctors and hospitals in your plan's network, except in emergencies, and you may need prior approval before seeing a specialist or having certain procedures.
  • You pay a copay or coinsurance each time you use care, and these costs count toward an annual out-of-pocket maximum that varies by plan.
  • Most plans cover preventive care (like annual checkups and screenings) with no copay, and many include dental, vision, or hearing coverage that Original Medicare does not.
  • Your coverage and costs change each year, so you must review your plan during the annual enrollment period (October 15 to December 7) to see if it still fits your needs.

Hospital and Inpatient Care Covered by Medicare Advantage

Medicare Advantage covers hospital stays the same way Original Medicare does: the plan pays for your room, meals, tests, and medications while you are admitted. However, you pay a copay or coinsurance for each hospital stay, and that amount varies by plan. Some plans charge a flat copay per admission (for example, $250 for the first three days, then $0 for days 4 through 7); others charge coinsurance, meaning you pay a percentage of the hospital bill.

Skilled nursing facility (SNF) care — rehabilitation or short-term nursing care after a hospital stay — is also covered, usually for up to 100 days per benefit period. You typically pay a copay per day for days 1 through 20, then coinsurance for days 21 through 100. The exact amounts depend on your plan.

The key limitation is that you must use a hospital or facility in your plan's network. If you go to an out-of-network hospital except in a true emergency, you may owe much more or the plan may not cover it at all. In an emergency, any hospital must treat you, and your plan will pay, but you should call your plan as soon as possible to notify them.

Doctor Visits and Outpatient Services

Medicare Advantage covers visits to primary care doctors, specialists, and urgent care clinics, but only if they are in your plan's network. You pay a copay at each visit — typically $10 to $50 for a primary care doctor and $25 to $75 for a specialist, depending on your plan. Some plans use coinsurance instead, meaning you pay a percentage of the cost.

To see a specialist, most Medicare Advantage plans require you to get a referral from your primary care doctor first. This is called a gatekeeper model, and it is designed to keep costs down. A few plans, called open access plans, let you see a specialist without a referral, but these are less common and may have higher copays.

Outpatient services — lab work, X-rays, physical therapy, mental health counseling, and other treatments you receive without being admitted to the hospital — are covered with a copay or coinsurance. Many plans cover a set number of physical therapy or mental health visits per year; once you reach that limit, you may have to pay out of pocket or get special approval to continue.

Prescription Drug Coverage Included in Your Plan

Unlike Original Medicare, Medicare Advantage includes prescription drug coverage as part of the plan. You do not need to buy a separate Part D plan. When you fill a prescription at a pharmacy in your plan's network, you pay a copay that varies by drug. Most plans use a formulary — a list of covered medications organized by tier — so your copay depends on which tier your drug is on.

Tier 1 drugs (usually generic) might cost $5 to $10 per prescription. Tier 2 (preferred brand-name) might be $25 to $50. Tier 3 (non-preferred brand-name) might be $50 to $100 or more. Some drugs are not on the formulary at all, meaning your plan will not cover them unless you get special approval from your doctor and the plan.

Like all Medicare drug plans, Medicare Advantage plans have an annual deductible (the amount you pay before the plan starts helping), a coverage gap (sometimes called the "donut hole"), and a catastrophic coverage phase. The deductible and gap amounts change each year. Once you reach catastrophic coverage, the plan covers most of the cost of your drugs for the rest of the year.

Preventive Care and Screenings at No Copay

Medicare Advantage must cover all preventive services that Original Medicare covers, and you pay nothing for them. This includes annual wellness visits, cancer screenings (mammogram, colonoscopy, Pap test), heart disease screenings, diabetes screenings, bone density tests, and vaccinations. You do not need a copay or deductible for these services when you use an in-network provider.

The catch is that preventive care is free only when it is truly preventive — a visit to check on an existing condition or to treat a symptom may not be free. For example, a colonoscopy for screening is free, but if your doctor finds a polyp and removes it during the same procedure, you may owe a copay for the treatment part.

Extra Benefits Many Plans Offer Beyond Original Medicare

Many Medicare Advantage plans include benefits that Original Medicare does not cover, such as dental (cleanings, fillings, extractions), vision (eye exams, glasses, contacts), and hearing (exams and hearing aids). Some plans also cover fitness programs, over-the-counter medications, or transportation to medical appointments. These extras vary widely by plan and by region, so you need to check your specific plan's benefits.

These extra benefits are a major reason people choose Medicare Advantage, especially if they need dental or vision care. However, they come with limits — for example, a dental plan might cover two cleanings per year and one exam, but not major work like crowns or root canals. Read your plan's summary of benefits to see exactly what is and is not covered.

Out-of-Pocket Costs and Annual Maximums

Every Medicare Advantage plan has an annual out-of-pocket maximum. Once your copays, coinsurance, and deductibles add up to that amount in a calendar year, your plan covers 100 percent of covered services for the rest of the year. The maximum varies by plan and changes each year, but it gives you a ceiling on what you can spend.

Keep in mind that the out-of-pocket maximum does not include your monthly premium — you still pay that every month no matter what. It also does not include costs for out-of-network care (unless it is an emergency), or costs for services your plan does not cover at all.

If you use a lot of care, the out-of-pocket maximum can save you money compared to Original Medicare. If you use very little care, a plan with a low premium but high copays might cost you more than Original Medicare. This is why comparing plans during the annual enrollment period matters.

What Medicare Advantage Does Not Cover

Medicare Advantage covers the same basic services as Original Medicare, so it does not cover long-term care (nursing home care for chronic conditions), custodial care (help with bathing or dressing), or most dental and vision care — unless your specific plan includes those extras. It also does not cover routine foot care, most acupuncture, or experimental treatments.

If you travel outside the United States, Medicare Advantage does not cover care abroad, with rare exceptions for emergencies in border areas. If you plan to spend time outside the country, check with your plan about what happens if you need care while traveling.

Frequently Asked Questions

Can I use any doctor I want with Medicare Advantage?

No. You must use doctors and hospitals in your plan's network. If you go out of network except in an emergency, you may owe the full cost or the plan may not cover it at all. You can check your plan's provider directory online or call the plan to confirm a doctor is in network before scheduling an appointment.

What happens if I need emergency care while traveling?

Medicare Advantage covers emergency care at any hospital, even out of network, as long as it is a true emergency. Call your plan as soon as possible to let them know. If you are traveling regularly or for an extended time, ask your plan about coverage before you leave.

Do I still need to pay for preventive care?

No. Preventive services like annual checkups, cancer screenings, and vaccinations are free with no copay when you use an in-network provider. However, if your doctor finds a problem during a preventive visit and treats it, you may owe a copay for the treatment portion.

What if my plan does not cover a drug my doctor prescribed?

Your doctor can ask your plan for an exception, called a prior authorization or formulary exception. The plan will review the request and decide whether to cover the drug or suggest a covered alternative. This process usually takes a few days, so ask your doctor to submit the request as soon as possible.

Can I switch Medicare Advantage plans if I do not like mine?

Yes, during the annual enrollment period (October 15 to December 7) you can switch to a different Medicare Advantage plan or switch to Original Medicare. You can also switch plans during the Medicare Advantage Open Enrollment Period (January 1 to March 31) if you are already in a Medicare Advantage plan. Outside these windows, you can only switch if you have a may have access to life event, such as moving out of your plan's service area.
