Medicare Advantage Plan Enrollment

Sponsors of Medicare Advantage (MA) health care plans approved by Medicare that accept applications for enrollment in one of the Medicare Advantage options that offer Part A (hospital) and Part B (medical) coverage. Prescription drug coverage may also be included. Many MA Plans offer extra benefits (e.g., vision coverage, dental coverage, hearing care, wellness services and nurse line support) and may offer lower co-payments than Original Medicare. However, MA plans may require participants to use physicians, hospitals and other providers that are part of the plan's provider network. Medicare Advantage Plans include: Medicare Health Maintenance Organization (HMO) Plans; Preferred Provider Organization (PPO) Plans; Private Fee-for-Service (PFFS) Plans; Medicare Special Needs Plans (SNP); and Medicare Savings Account Plans (MSA Plans). To join a MA Plan, an individual must be enrolled in Medicare Part A and Part B. In addition to paying the monthly Part B premium required by Medicare, MA Plans may require a monthly premium for the extra benefits provided by the Plan. Information about Medicare Advantage plans is available in the "Welcome to Medicare" handbook people receive when they enroll, by calling 1-800-MEDICARE or by using the Plan Finder on the Medicare website.
