  • You or your spouse must have worked long enough to be eligible for Social Security or Railroad Retirement benefits.

  • You or your spouse must be government employees or retirees who have not paid into Social Security but have paid Medicare payroll taxes.

SD Medicare Advantage enrollees by plan type

The chart below illustrates the percentage of 2019 South Dakota Medicare Advantage enrollees that are enrolled in each primary type of Medicare Advantage plan.1

Plan type Percentage of South Dakota enrollees (2019)
Medicare Cost Plan 88.2%
Local PPO 9%
HMO 2.4%
PFFS <1%
Other Plans <1%

The major types of Medicare Advantage plans include:

  • HMO
    Health Maintenance Organization (HMO) usually requires patients to use health care providers and pharmacies that are part of the plan’s network (except in the case of emergencies) while also typically requiring a referral from a primary care doctor in order to see a specialist.

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

    Beneficiaries in this type of plan 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 and how much the patient will pay when care is received.

    With a PFFS plan, you can typically receive care from any doctor, hospital or health care provider that accepts 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.

    Typically, you must receive care from health care providers and hospitals within your SNP network, except for in cases when you need emergency or urgent care and when someone who has End-Stage Renal Disease (ESRD) needs out-of-area kidney dialysis.

Not all of these types of plans may be available in your area. A licensed insurance agent can help you compare the types of 2019 South Dakota Medicare Advantage plans that are available where you live.
