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.
Medicare Advantage Plan Types
HMO (Health Maintenance Organization)
Typically requires you to choose a primary care doctor and get referrals to see specialists. Usually the lowest-cost plan type, but the least flexible on provider choice.
PPO (Preferred Provider Organization)
Lets you see out-of-network providers, usually at a higher cost, and generally doesn't require referrals to see specialists.
SNP (Special Needs Plan)
Designed for people with specific chronic conditions, those who qualify for both Medicare and Medicaid, or those in certain institutional settings.

Frequently Asked Questions
What is Medicare Advantage?
Medicare Advantage (Part C) is a way to get your Medicare Part A and Part B benefits through a private insurance company approved by Medicare, often bundled with extra benefits like dental, vision, hearing, and prescription drug coverage.
Is Medicare Advantage free?
Many Medicare Advantage plans have a $0 monthly premium, but you still pay your Medicare Part B premium ($202.90/month in 2026), plus any copays, coinsurance, or deductibles the specific plan charges.
What is the difference between HMO and PPO Medicare Advantage plans?
HMO plans generally require you to use in-network doctors and get referrals for specialists, while PPO plans offer more flexibility to see out-of-network providers, usually at a higher cost.
Can I use any doctor with Medicare Advantage?
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.
When can I enroll in a Medicare Advantage plan?
You can enroll during your Initial Enrollment Period around your 65th birthday, during the Annual Enrollment Period (October 15 – December 7), or during the Medicare Advantage Open Enrollment Period (January 1 – March 31) if you're already enrolled in a Medicare Advantage plan.
Does Medicare Advantage cover prescription drugs?
Most Medicare Advantage plans (MAPD plans) include Part D prescription drug coverage bundled in, but not all — it's important to confirm before you enroll.
Can I switch from Medicare Advantage back to Original Medicare?
Yes. You can switch back to Original Medicare during the Annual Enrollment Period or the Medicare Advantage Open Enrollment Period, though you may need to answer medical underwriting questions if you also want to add a Medigap plan outside your initial window.
What are the downsides of Medicare Advantage?
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 matters.
