The network providers listed in this directory have agreed to provide you with health care services. You may go to any of our network providers listed in this directory; however, some services may require a referral.

About the Great Plains Medicare Advantage Provider Network

Our network providers are the doctors, health care professionals, medical groups, hospitals, and other health care facilities that have an agreement with Great Plains Medicare Advantage to accept our payment and your cost-sharing amount as payment in full.

We have arranged for these providers to deliver covered services to members in our plan. The providers in our network bill us directly for the care they provide to you. When you see a network provider, you pay only your share of the cost for their services. You should use network providers for all your services.

Out-of-Network Providers

Only in limited cases, may you receive covered services from out-of-network providers. These cases include:

  • A medical emergency – go to the closest available provider
  • Urgently needed services – go to any qualified provider when out of the Plan’s service area, or when network providers are unavailable
  • Renal dialysis that you receive when you are outside the Plan’s service area
  • Services that have been approved in advance by Great Plains Medicare Advantage, and
  • Any services which were covered through the appeals process

You should always see a network provider unless one of the limited cases mentioned above applies. If you choose to receive services from an out-of-network provider, they must request prior approval from Great Plains Medicare Advantage unless it is an emergency to an acute care hospital.

If you receive a bill from an out-of-network provider, you should not pay the bill, unless you have received an Explanation of Benefits (EOB) that details what the plan will pay for your service, and any remaining balance you will need to pay. If you receive a bill from an out of network provider, but have not yet received an EOB, please submit the bill to Great Plains Medicare Advantage or ask the provider to submit the bill to Great Plains Medicare Advantage for you. The out-of-network provider may also bill you for any remaining balance not paid by Great Plains Medicare Advantage.

If you have already paid for the covered services, Great Plains Medicare Advantage will reimburse you for our share of the cost (if prior approval was obtained). If you have any questions, visit our “how to file an appeal” section of our website located at call our Member Services Department at 1-844-637-4760 (TTY 888-279-1549).

Payment for services is contingent upon:

  • The services you received are included in Great Plains Medicare Advantage benefits as outlined in the Evidence of Coverage (EOC) that can be found on the plan website.
  • The provider, or medical facility, you received services from is eligible for payment from Great Plains Medicare Advantage
  • The service(s) meet requirements for medical necessity.
  • An authorization or referral was obtained.

Note: Temporary out-of-network dialysis services when you are out of the service area, medical emergencies, and urgently needed medical services do not require notification or preauthorization for payment.

You must use plan providers except in emergency or urgent care situations. If you obtain routine care from out-of-network providers, neither Medicare nor Great Plains Medicare Advantage will be responsible for the costs.
