Choose Your Provider with a Medicare Supplement Plan

With an Avera Health Plans Medicare Supplement policy, you have the freedom to choose your doctor - and there's no need for a referral - for basic care.

To receive full plan benefits when you need hospital or outpatient surgery services, make sure your provider has admitting privileges at an in-network hospital. If not, ask for a referral to a provider who does.

In-Network Hospitals for Medicare Supplement Select Plans

With a Medicare Supplement Select plan, you can still see any doctor for primary care services, but you must use in-network hospitals for outpatient surgery or hospital-based care, including any laboratory, imaging or office visits that process billing through the hospital. View our Network Hospital Directory for Select plans.
