In general, a Medicare Advantage plan is a health plan option approved by the Centers for Medicare & Medicaid Services (CMS) and operated by a private insurance company.  Sometimes, you will hear a Medicare Advantage plan called a "Medicare Part C plan" or a Medicare Health plan.

A Medicare Advantage MAPD (or MA-PD )includes Medicare Part D prescription drug coverage and a Medicare Advantage MA plan does not include drug coverage.

Both MA and MAPD Medicare Advantage plans provide a combination of your Medicare Part A (in-patient or hospital coverage) and Medicare Part B (out-patient or physician coverage) and may also include other "supplemental" service such as limited home healthcare, vision coverage, dental coverage, transportation, and recreational coverage (such as a "Silver Sneakers" membership).

Important:  You may not be able to add Medicare drug coverage to an MA.

If you join an MA plan (without prescription drug coverage), you may not be allowed to also add a stand-alone Medicare Part D prescription drug plan (PDP).  If you want prescription drug coverage and want to join a Medicare Advantage plan, then you probably should choose an MAPD.  Only MSAs and PFFS Medicare Advantage plans can add stand-alone Medicare Part D drug coverage (see more below).  However, if you receive VA drug coverage, you can join an MA plan and use your creditable VA drug coverage or you can join an MAPD plan and use either your VA drug coverage or your MAPD drug coverage (but not both at the same time).

A note on Medicare Advantage plans and Healthcare Networks

Most MAs and MAPD have healthcare networks and you may need to visit doctors (or other healthcare providers) who are part of the Medicare Advantage plan network - or be prepared to pay a higher coverage cost.

Types of Medicare Advantage Plans (MA and MAPD)

You can use our Medicare Advantage Plan Finder to browse through the Medicare Advantage plans.  As you review plan in your ZIP Code region, you might notice some common types of Medicare Advantage plans.

• HMO - Health Maintenance Organization plans
  
  HMOs are wellness-based Medicare Advantage plans and usually have the most-restrictive healthcare provider network, meaning that your healthcare costs may be considerably higher if you go outside of your plan’s established network. Also, depending on your HMO plan, you may only be allowed outside of your plan network with a referral from your doctor. Local HMOs are often very affordable compared to other Medicare Advantage plans because the restrictive network and focus on wellness helps to control healthcare costs. The majority of Medicare Advantage plans will be HMOs (Health Maintenance Organizations).
  
  
• HMO-POS - Health Maintenance Organizations Point-of-Service plans
  
  These Medicare Advantage HMO’s have a more flexible healthcare network allowing you to seek care outside of your plan’s network by paying a higher cost-sharing rate. This type of HMO is chosen often for people who travel part of the year, but still return home for the majority of their healthcare needs. For instance, you may have a $30 co-payment when you visit a healthcare provider in-network (at home) and pay $60 when you visit a provider outside of the plan’s network (while traveling).
  
  Important:
  (1) Sometimes an HMO POS plans will convert to HMOs (without the POS option) for the following plan year. 
  (2) Depending on your HMO POS, you may find that out-of-network costs do not apply to your plan's that your Maximum Out-of-Pocket (MOOP) limit - check with your plan's Member Services for more details.
  
  
• PPO - Preferred Provider Organization plans
  
  Medicare Advantage PPOs have a less-restrictive provider network, but again, you probably will pay a higher cost-sharing rate when you visit a healthcare provider outside of your plan’s network.

• PFFS - Private Fee for Service plans
  
  Although popular several years ago, fewer Medicare Advantage PFFS plans are now available.  PFFS plans have the most flexible network, meaning that you can go to any health care provider as long as they accept Medicare and the terms and conditions of your PFFS plan.  As noted, PFFS plans are rare, but some people still find PFFS plans as a flexible and economic alternative to other Medicare Advantage plans.
  
  
• SNP - Special Needs Plans
  
  SNPs are Medicare Advantage plans designed for a people with specific conditions or financial needs. Certain SNPs are available only to diabetics, people with chronic cardiac conditions, nursing home residents, or people eligible for both Medicare and Medicaid (D-SNPs). If you do not have the plan’s “special need”, you will not be allowed to join (or stay in) the SNP.
  
  
• MSA - Medical Savings Account plans
  
  MSAs are like Health Savings Accounts (or HSAs) or a high-deductible health plan combined with a spending account that you can use to pay for your health care costs. MSAs do not provide prescription drug coverage and you would need to join a separate Medicare Part D plan for your prescription needs. In 2025, MSAs are only available in Wisconsin.
  
  
• MMP - Medicare-Medicaid Plans
  
  MMP plans were introduced in 2014 and are only offered in a few locations across the country. As noted by CMS:
  

  "A Medicare-Medicaid Plan (MMP) [like a D-SNP] is a private health plan that has been competitively selected and approved to provide integrated care to eligible full-benefit Medicare-Medicaid enrollees under the CMS Financial Alignment Demonstration."
  (CMS, “Financial Alignment Initiative,” (www.cms.gov/ Medicare-Medicaid-Coordination/ Medicare-and-Medicaid-Coordination/ Medicare-Medicaid-Coordination-Office/ FinancialModelstoSupportStates EffortsinCareCoordination.html.)

  MMPs only serve full benefit dual (Medicare/Medicaid) eligible beneficiaries and some additional limitations may apply.
