What Is Medicare Advantage?
Medicare Advantage (also called Part C) is a way to get your Medicare benefits through a private insurance company instead of directly through the government. By law, every Medicare Advantage plan must cover everything Original Medicare (Part A and Part B) covers. Plans are allowed to charge different copays for that coverage, and most add extra benefits on top of it.
Most Medicare Advantage plans also bundle in Part D prescription drug coverage (these are called MA-PD plans). So instead of juggling separate Part A, Part B, and Part D coverage, you typically carry one plan and one card.
Medicare Advantage vs. Original Medicare: The Core Tradeoff
Every Medicare decision comes down to a tradeoff between flexibility and cost predictability:
- Original Medicare lets you see almost any doctor or hospital in the country that accepts Medicare, but you typically pay a percentage of costs (coinsurance) with no yearly cap on what you could owe, unless you also have a Medicare Supplement policy.
- Medicare Advantage usually charges flat copays instead of percentages, and includes a yearly limit on what you'll pay out of pocket, but you're generally limited to the plan's provider network and may need referrals for specialists.
What Extra Benefits Do Medicare Advantage Plans Offer?
This is the main reason Medicare Advantage has become so popular. On top of your Part A and Part B coverage, plans commonly include:
- Dental, vision, and hearing aid coverage
- Often a $0 monthly plan premium (you still owe your Part B premium)
- Fitness program memberships
- Transportation to medical appointments
- An over-the-counter allowance for everyday health items
Exactly which extras are included varies a lot by plan and county. We'll show you what's actually available where you live.
HMO vs. PPO Medicare Advantage Plans
Most Medicare Advantage plans come in one of two network structures:
- HMO: you generally must use in-network providers (except true emergencies) and need a referral to see specialists. Usually the lower-cost option.
- PPO: you can see out-of-network providers for a higher cost, and you usually don't need referrals. More flexible, often a higher premium.
Star Ratings Matter
Medicare rates every Medicare Advantage plan from 1 to 5 stars each year based on quality and member satisfaction. If a 5-star Medicare Advantage, Cost, or Part D plan is available where you live, you can use a 5-Star Special Enrollment Period to switch into one once between December 8 and November 30 of the following year. That is not a year-round, unlimited switch.
When Can You Enroll or Switch?
- Initial Enrollment Period: starts 3 months before you get Medicare and ends 3 months after (a 7-month window). You need both Part A and Part B to join a Medicare Advantage plan.
- Annual Enrollment Period: October 15 to December 7 every year, with changes taking effect January 1.
- Medicare Advantage Open Enrollment Period: January 1 to March 31, for people already in an MA plan to switch to a different MA plan or back to Original Medicare (one change allowed).
Is Medicare Advantage Right for You?
It's often a strong fit if you're comfortable using a network of doctors, want built-in extra benefits like dental and vision, and like having a cap on your yearly costs.
You may want to look at Medicare Supplement instead if you travel frequently or split time between states, want to see any doctor without worrying about networks, or want the most predictable costs possible.
