What a Medicare Advantage Plan Is
When you join a Medicare Advantage plan (also called Part C), you still have Medicare — you keep paying your Part B premium and you keep your rights — but your Part A and Part B benefits are delivered by a private plan instead of by Original Medicare. Most plans also include Part D drug coverage ("MAPD" plans) and extras Original Medicare never covers.
To join you need Part A and Part B, and you must live in the plan's service area (usually a county). You can join, switch or drop a plan during the enrollment periods set by Medicare.
What People Like About It
- Low monthly cost. Many plans have a $0 monthly plan premium. You still pay your Part B premium ($202.90 standard in 2026), and some plans even pay part of it back ("Part B giveback").
- A yearly limit on what you pay. Every Advantage plan sets a maximum out-of-pocket for covered in-network medical care (Medicare caps that maximum each year; many plans set theirs lower). Original Medicare alone has no such limit.
- Extras. Dental, vision, hearing, over-the-counter allowances, fitness programs and transportation are common. Which extras, and how generous, varies widely by plan and county.
- One card, one plan. Simpler than juggling Medigap plus Part D.
What to Weigh Carefully
- Networks. HMO plans generally require you to use the plan's doctors and hospitals (except emergencies) and may require referrals. PPO plans let you go out of network at a higher cost. Before we recommend any plan, we check that your doctors, hospital and pharmacy are in it.
- Prior authorization. Many services need plan approval first. Medicare has tightened the rules plans must follow, but it is still part of how these plans work.
- Costs when you use care. Copays and coinsurance for hospital stays, specialists, imaging and drugs add up in a year when you're sick. The out-of-pocket maximum is a ceiling, not a typical year — but it matters.
- Travel. Coverage away from home is usually limited to emergencies and urgent care; snowbirds should look at PPO plans or at a Supplement instead.
- Switching later. If you leave Advantage for Original Medicare after your first year, a Medigap insurer can usually ask health questions and may decline you (except in states with special rules or if you qualify for a guaranteed-issue right).
HMO, PPO, PFFS and Special Needs Plans
HMO: lowest cost, network only, primary doctor coordinates care. HMO-POS: an HMO that allows some out-of-network services. PPO: more freedom, usually higher premiums or copays. PFFS: you can see any provider who agrees to the plan's terms. Special Needs Plans (SNPs): designed for people with Medicaid, certain chronic conditions, or living in a facility — see our D-SNP guide.

Common Questions
Can I keep my doctor with Medicare Advantage?
Only if your doctor is in the plan's network (HMO) or you're willing to pay more out of network (PPO). Networks change each year, which is why we verify your doctors against the plan's current directory before you enroll and again during every fall review.
Is a $0 premium plan really free?
No plan is free. $0 refers to the plan's own monthly premium. You still pay your Medicare Part B premium, and you pay copays and coinsurance when you use care, up to the plan's yearly in-network maximum.
Can I switch from Medicare Advantage to a Supplement later?
You can return to Original Medicare during the Annual Enrollment Period or the January–March Open Enrollment Period. Getting a Medigap policy afterward may require medical underwriting unless you have a guaranteed-issue right — for example, within the 12-month trial right when you first joined Advantage at 65.
Do Medicare Advantage plans cover me when I travel?
Emergency and urgent care are covered anywhere in the U.S., and some plans include worldwide emergency coverage. Routine care away from home is generally not covered by HMO plans; some PPO plans have travel benefits. Tell us how you travel and we'll filter plans accordingly.
Who should not choose Medicare Advantage?
People who see many specialists in different systems, who split the year between two states, who want to avoid prior authorization, or who want the lowest possible cost in a bad health year often do better with Original Medicare plus a Supplement and Part D. It depends on your situation, which is the point of the review.
