What is Medicare Advantage?
Medicare Advantage, also called Medicare Part C, is another way to receive your Medicare Part A and Part B benefits through a private insurance company approved by Medicare. You remain enrolled in Medicare, but the Medicare Advantage plan administers your covered medical benefits.
Many Medicare Advantage plans also include Part D prescription drug coverage, and some may offer additional benefits such as dental, vision, hearing, fitness, transportation, or over-the-counter allowances. Benefits vary by plan and location.
What Medicare Advantage plans may include
- Part A and Part B covered services
- Part D prescription drug coverage in many plans
- An annual out-of-pocket maximum for covered Part A and Part B services
- Additional benefits that may include dental, vision, hearing, fitness, transportation, or OTC benefits
- Special benefits available through certain plan types or eligibility categories
How the costs work
Some Medicare Advantage plans have a $0 additional plan premium. You must continue paying your Medicare Part B premium, and other costs such as deductibles, copayments, coinsurance, and prescription costs can still apply.
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 use the plan's network for non-emergency care and may need a primary care provider or referrals for certain services, depending on the plan.
- PPO (Preferred Provider Organization): PPO plans generally allow both in-network and out-of-network care, although you may pay more when using providers outside the network. Referral requirements vary by plan.
- 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 may prefer Medicare Advantage
Medicare Advantage may appeal to people who:
- Prefer having medical and often prescription coverage combined in one plan
- Are comfortable using a plan's provider network
- Want an annual limit on covered Part A and Part B out-of-pocket costs
- Find additional plan benefits valuable
- Have doctors, hospitals, and prescriptions that work well with plans available in their area
Original Medicare with a Medicare Supplement may be worth comparing if you:
- Want broader provider access across the country
- Travel frequently or live in more than one state
- Prefer fewer network restrictions
- Prefer a different balance between monthly premiums and medical cost sharing
In those situations, it may be helpful to compare Medicare Advantage with Original Medicare plus a Medicare Supplement. The right fit depends on your providers, travel needs, prescriptions, budget, and how you prefer to manage out-of-pocket costs.
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.
