What Is Medicare Advantage?

Medicare Advantage, also called Part C, is an alternative way to receive your Original Medicare (Part A and Part B) benefits through a private insurance company that contracts with Medicare. Most Medicare Advantage plans also bundle in Part D prescription drug coverage and extra benefits Original Medicare doesn't offer — routine dental, vision, hearing aids, and sometimes fitness memberships or over-the-counter allowances.

In exchange, Medicare Advantage plans generally use a provider network, meaning your choice of doctors and hospitals may be more limited than under Original Medicare, and some services may require prior authorization or a referral.

What Types of Medicare Advantage Plans Are There?

HMO and HMO-POS (Health Maintenance Organization)

HMOs generally use a provider network and may require referrals. An HMO Point-of-Service option may cover some out-of-network care at a higher cost. Check the plan's Evidence of Coverage and provider directory.

PPO (Preferred Provider Organization)

May cover care from out-of-network providers at a higher cost. Provider rules, referrals, and costs vary by plan.

PFFS (Private Fee-for-Service)

The plan sets its payment terms. You may receive care from Medicare-approved providers who agree to the plan's terms for that service; some PFFS plans have networks. Check provider participation and whether drug coverage is included.

SNP (Special Needs Plan)

For people who meet specific eligibility criteria, including certain chronic conditions, qualifying for both Medicare and Medicaid, or living in certain institutions. All SNPs include Part D drug coverage.

MSA (Medical Savings Account)

Combines a high-deductible Medicare Advantage plan with a medical savings account funded by the plan. You use the account toward Medicare-covered costs before the deductible; MSA plans do not include Part D, so drug coverage requires a separate Medicare drug plan.

Plan availability and terms vary by area. Compare Medicare Advantage plan types at Medicare.gov and review each plan's materials.

Initial Enrollment Period (IEP): the 7-month window around your 65th birthday.
Annual Enrollment Period (AEP 2026): October 15 – December 7, open to everyone, for Plan Year 2027 coverage.
Medicare Advantage Open Enrollment Period (MA OEP): January 1 – March 31, for those already in a Medicare Advantage plan who want to switch plans or return to Original Medicare.
Special Enrollment Periods (SEPs): triggered by qualifying life events like moving or losing other coverage.

Not necessarily — Medicare Advantage plans use provider networks. You'll want to confirm your doctors and hospitals are in-network before enrolling, especially with an HMO plan.

Medicare Advantage plans use provider networks (which can limit doctor choice), may require referrals or prior authorization, and annual out-of-pocket maximums, formularies, and networks can change year to year — reviewing your plan annually during AEP 2026 matters.
