what is the difference between a hmo and a ppo medicare advantage plan
What is a Medicare HMO? What are the differences between HMOs and PPOs? There are four main types of Medicare Advantage plans, but Health Maintenance Organization (HMO) plans and Preferred Provider Organization (PPO) plans are the most common types. Here is a comparison of the two varieties: 1  HMO plans require that beneficiaries see health-care providers, doctors, and hospitals within the planâs network except in urgent and emergency situations. 2  PPO plans do not require that beneficiaries use in-network providers and do not require a referral to see a specialist.
