What should I do before enrolling in a Medicare Advantage Plan?

Health Maintenance Organizations (HMOs), Preferred Provider Organizations (PPOs), Private Fee-for-Service (PFFS) Plans, and Special Needs Plans are the four primary categories of Medicare Advantage Plans. Health maintenance organizations (HMOs) are among the best Medicare Advantage Plans. HMO stands for Health Maintenance Organization. PPO stands for Preferred Provider Organization. Patients with HMOs are restricted to receiving treatment from physicians and hospitals affiliated with the HMO's network. This type of coverage is the least all-encompassing of the three.
