What Is Medicare Advantage?
Medicare Advantage (also called Medicare Part C) is an alternative way to get your Medicare coverage through a private insurance company approved by Medicare. Instead of receiving your benefits directly from the federal government through Original Medicare (Parts A and B), you enroll in a Medicare Advantage plan that provides all your Part A and Part B benefits — and usually much more.
In 2026, more than 33 million Americans are enrolled in Medicare Advantage plans, representing over 54% of all Medicare beneficiaries. The primary appeal: most plans offer $0 monthly premiums, and many include additional benefits like dental, vision, hearing, and prescription drug coverage that Original Medicare does not provide.
Medicare Advantage vs. Original Medicare
The fundamental choice every Medicare-eligible person faces is whether to stay with Original Medicare (Parts A & B, plus optional Part D for drugs and Medigap for supplemental coverage) or switch to a Medicare Advantage plan. See our detailed Medicare Advantage vs Original Medicare comparison for a full breakdown.
Key differences at a glance:
- Cost: Many MA plans have $0 premiums. Original Medicare has standard Part B premium (~$185/mo in 2026).
- Network: MA plans generally have networks. Original Medicare is accepted by most US providers.
- Extra benefits: MA often includes dental, vision, and hearing. Original Medicare does not.
- Out-of-pocket cap: MA plans have an annual out-of-pocket maximum. Original Medicare has no cap.
Types of Medicare Advantage Plans
- HMO (Health Maintenance Organization): Requires you to use in-network providers except in emergencies. Usually the lowest cost option.
- PPO (Preferred Provider Organization): More flexibility to see out-of-network providers, but at higher cost. No referrals needed.
- HMO-POS (Point of Service): Hybrid — HMO structure with limited out-of-network access.
- PFFS (Private Fee-for-Service): You can see any provider who accepts the plan's terms.
- SNP (Special Needs Plan): For people with specific chronic conditions, dual-eligibility (Medicare + Medicaid), or institutional needs.

Medicare Advantage Costs Explained
Even with a $0 premium plan, you still pay certain costs when you use care. Understanding these helps you estimate your total annual spend:
- Premium: Your monthly cost for the plan (often $0 for MA).
- Deductible: Amount you pay before coverage begins (varies by plan).
- Copays/Coinsurance: Your share of costs each time you receive care.
- Out-of-Pocket Maximum: The most you'll pay for covered services in a year. In 2026, the maximum is $9,350 for in-network services.

Prescription Drug Coverage (MAPD)
Most Medicare Advantage plans include Part D prescription drug coverage — these are often called MAPD plans (Medicare Advantage + Prescription Drug). If you're on regular medications, choosing a plan that includes drug coverage in your premium is often more cost-effective than buying a separate Part D plan. See our guide on Medicare Advantage prescription drug coverage to compare formularies and drug tiers.
Extra Benefits Most People Don't Know About
Medicare Advantage plans frequently offer supplemental benefits that Original Medicare doesn't cover:
- Dental cleanings, fillings, and allowances for major dental work
- Vision exams and an annual allowance for glasses or contacts
- Hearing aids and routine hearing exams
- Fitness memberships (SilverSneakers or similar programs)
- Transportation to medical appointments
- Over-the-counter allowances for medications and health items
- Meal delivery after a hospital stay

Medicare Advantage Star Ratings
Medicare rates every Medicare Advantage plan annually on a 1–5 star scale based on quality measures including customer satisfaction, chronic condition management, and preventive care. Plans rated 4 stars or above are generally considered high quality. See our Medicare Advantage star ratings guide to understand what the ratings mean and how to use them when choosing a plan.
Medicare Advantage vs. Medigap (Supplemental Insurance)
Some people prefer to keep Original Medicare and add a Medigap (Medicare Supplement) policy to cover the gaps in Original Medicare coverage. This strategy offers maximum provider flexibility but usually costs more per month. Read our Medicare Advantage vs. Medigap comparison to decide which approach fits your health needs and budget.
