IL Medicare Advantage plans by plan type

The major types of Medicare Advantage plans include:

  • HMO
    With a Health Maintenance Organization (HMO), you are usually required to use health care providers and pharmacies that are part of the plan’s network (except in the case of emergencies).

    You are also typically required to get a referral from a primary care doctor in order to see a specialist if you have an HMO plan.

  • PPO
    Medicare Advantage beneficiaries in a Preferred Provider Organization (PPO) can typically see providers outside of their plan’s network, often at a higher cost.

    PPO plan beneficiaries typically pay less out of pocket if they choose to receive medical services from providers within their plan’s network.

    PPO plans typically do not require patients to acquire a referral before visiting with a specialist.

  • PFFS
    A Private Fee-For-Service (PFFS) plan determines how much it will pay to health care providers when care is received.

    With a PFFS plan, you can typically receive care from any doctor, hospital or health care provider that accepts Medicare and your plan’s terms. Not all providers will accept these terms, however.

  • SNP
    A Special Needs Plan (SNP) is a type of Medicare Advantage plan limited to people with certain chronic conditions and other specific characteristics.

    A Medicare SNP is required to provide prescription drug coverage.

Not all of these types of plans may be available in your area. A licensed insurance agent can help you compare the types of 2022 Illinois Medicare Advantage plans that are available where you live.
