Are Medicare Advantage plans HMOs?

There are different types of Medicare Advantage Plans.

In a Health Maintenance Organization (HMO) Medicare Advantage plan, you can typically only go to health care providers in the plan’s network unless it is an urgent or emergency situation. For some HMO plans you may need to get a referral from your primary care physician to see other specialists.

In a Preferred Provider Organization (PPO) Medicare Advantage Plans, you typically have more flexibility to choose providers that do not belong to the plan’s network, but it may cost more. Please note that Medicare Advantage Plans are offered by private insurance companies and that benefits vary by plan.
