How Medicare Advantage Plans Work

Instead of getting coverage directly from Original Medicare, you receive your benefits through a Medicare-approved plan that bundles services together.
Understanding how these plans work can help you choose the right coverage for your needs.

What Is Medicare Advantage (Part C)?
Medicare Advantage, also known as Part C, is a type of Medicare plan offered by private insurance companies.
These plans are required to provide at least the same level of coverage as Original Medicare.
Most plans also include additional benefits not covered by Original Medicare.
What Medicare Advantage Plans Cover
All Medicare Advantage plans include:
Hospital coverage (Part A)
Medical coverage (Part B)
Many plans also include:
Prescription drug coverage (Part D)
Dental, vision, and hearing benefits
Wellness programs and preventive services
Coverage varies by plan, so it’s important to review details carefully.
How Medicare Advantage Differs from Original Medicare
Medicare Advantage plans work differently than Original Medicare.
Key differences include:
Network restrictions — you may need to use doctors within a plan network
Bundled coverage — services are combined into one plan
Out-of-pocket limits — plans include a maximum yearly limit
Additional benefits — often include services not covered by Original Medicare
These differences can affect both your costs and how you access care.
Types of Medicare Advantage Plans
There are several types of Medicare Advantage plans, including:
HMO (Health Maintenance Organization) — requires use of in-network providers
PPO (Preferred Provider Organization) — allows more flexibility with providers
Special Needs Plans (SNPs) — designed for specific health conditions or situations
Each plan type has different rules and levels of flexibility.
What Medicare Advantage Plans Cost
Costs vary depending on the plan, but typically include:
A monthly premium (some plans may have $0 premiums)
Copayments or coinsurance for services
Out-of-pocket maximums for the year
You must still pay your Part B premium even if you enroll in a Medicare Advantage plan.
