Health Maintenance Organization
Usually uses a defined provider network and may require a primary care doctor or referrals for certain specialist care.
Medicare Part C
Medicare Advantage is another way to receive your Part A and Part B benefits through a private plan approved by Medicare.
Part C basics
You still have Medicare, but the plan manages how you receive your covered services.
To join a Medicare Advantage plan, you must be enrolled in Part A and Part B. The private plan then provides your Part A and Part B benefits and may set rules for providers, referrals, and covered services.
Many plans include prescription drug coverage and may offer additional benefits. Plan availability, networks, benefits, and costs vary by location and can change each year.
Common plan types
Start by understanding how each type may affect your doctors, referrals, and costs.
Usually uses a defined provider network and may require a primary care doctor or referrals for certain specialist care.
Usually offers more provider flexibility, but care outside the plan network may cost more.
Designed for people who meet specific health, coverage, or living situation requirements.
Some areas may offer other plan types, including Private Fee for Service or Medical Savings Account plans.
Coverage and benefits
Every plan must provide the Part A and Part B benefits Medicare requires. Additional benefits and plan rules differ.
Benefits are not the same in every plan. Review the plan documents for your location before enrolling.
Before you compare
Costs, eligibility, and availability can change from one plan or location to another.
You usually continue paying your Part B premium. The plan may also have premiums, deductibles, copayments, coinsurance, and an annual limit on covered medical costs.
You must be enrolled in both parts and meet the plan requirements to join.
Plans are offered in defined service areas. Moving may change the plans available to you or create a chance to choose new coverage.
Enrollment and changes
The enrollment period available to you depends on whether you are new to Medicare, already enrolled, or experiencing a qualifying life event.
You may be able to join during your Initial Enrollment Period, an annual Medicare enrollment period, or a Special Enrollment Period.
Check your doctors, prescriptions, pharmacy, total costs, travel needs, and coverage priorities.
After enrollment, use the plan membership card and review the plan rules before receiving care or filling prescriptions.
Compare your coverage paths
