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 from the federal government. Medicare pays the insurer a set monthly amount to provide your coverage, and the plan is required to cover at least the same medical benefits as Original Medicare (Parts A and B).
Most Medicare Advantage plans also bundle prescription drug coverage (Part D) into the same plan. These are called Medicare Advantage Prescription Drug (MAPD) plans, and they're the most common type.
What Medicare Advantage plans typically cover
- Everything Original Medicare covers (hospital, doctor, lab, etc.)
- Prescription drugs (in most plans)
- An annual out-of-pocket maximum: a cap on what you pay in a year for covered Part A and B services. Once you hit it, the plan pays 100%.
- Extras like dental, vision, hearing aids, fitness benefits, transportation to medical appointments, and over-the-counter allowances (varies by plan)
- Some plans offer additional benefits for chronically ill members
How the costs work
You continue to pay your monthly Part B premium to Medicare, and you may also pay a separate monthly premium to the Medicare Advantage plan. Many plans have a $0 plan premium, but that's on top of Part B, not instead of it.
When you use care, you typically pay copays or coinsurance for each service (a flat $20 for a primary care visit, $40 for a specialist, a percentage for a hospital stay, etc.). Each plan publishes its specific cost-sharing in a document called the Summary of Benefits.
The annual out-of-pocket maximum is one of the biggest differences from Original Medicare. Once your covered costs hit the maximum, the plan pays 100% of covered services for the rest of the year.
HMO, PPO, and other network types
Medicare Advantage plans use different network structures. The most common types:
- HMO (Health Maintenance Organization): You generally must use in-network doctors and hospitals except for emergencies. Often requires a primary care doctor and referrals to see specialists. Lower premiums in exchange for less flexibility.
- PPO (Preferred Provider Organization): You can see out-of-network providers, but pay more for doing so. No referrals usually required. More flexibility, often with a slightly higher premium.
- HMO-POS (Point of Service): An HMO that allows some out-of-network care for specific services.
- PFFS (Private Fee-for-Service): You can see any provider that agrees to the plan's payment terms (less common).
- SNP (Special Needs Plan): Plans designed for people with specific conditions, those with both Medicare and Medicaid (dual-eligibles), or those living in long-term care institutions.
Who Medicare Advantage works well for
Medicare Advantage tends to be a strong fit when:
- You want one card and one plan for hospital, medical, and prescription coverage
- You value extras like dental, vision, hearing aids, or fitness benefits
- You prefer predictable copays at the point of service over a higher monthly premium
- Your doctors and pharmacies are in-network for the plans available in your area
- You don't travel out of state often for care
It tends to be less ideal when:
- You want to see any provider nationwide without network restrictions
- You travel frequently and may need non-emergency care in other states
- You see many specialists and don't want to deal with referrals
- You want very predictable monthly costs and minimal cost-sharing at the point of service
In those cases, Medicare Supplement (Medigap) plans may be a better match. Our comparison of both routes breaks down both routes.
How to enroll in a Medicare Advantage plan
You can join, switch, or drop a Medicare Advantage plan during specific enrollment windows:
- Initial Enrollment Period: the 7-month window around your 65th birthday
- Annual Enrollment Period (AEP), October 15 to December 7 each year, for coverage starting January 1
- Medicare Advantage Open Enrollment Period, January 1 to March 31 each year, for people already in an Advantage plan
- Special Enrollment Periods: triggered by qualifying life events such as moving, losing other coverage, or qualifying for Extra Help
To enroll, you need to have Medicare Parts A and B, and live in the plan's service area. A licensed agent can help you compare plans, see if your doctors and medications are covered, and walk you through the enrollment paperwork.
