Assistance Available

If you need assistance during this process, contact our provider application and credentialing area:

Step 1: Determine Eligibility

To apply to Wellmark, you need to be in an eligible location and eligible contracting provider type as shown below. To provide services that can be considered for benefits, you must first apply with Wellmark. In its sole discretion, Wellmark reserves the right not to process or accept a provider's application. Wellmark will notify you of your effective date.


After you apply, Wellmark will be able to identify basic information about you when a claim is submitted, such as your National Provider Identifier (NPI), location, provider type, and specialty. Your services will be eligible for coverage beginning with your effective date; services provided prior to that date are not covered.


If eligible, you may decide to participate with one or more Wellmark networks. If you are interested in participation, you need to complete Step 3. You will find a list of participation advantages under Step 2. 


Eligible Practice Locations

Your location determines whether or not you are eligible to apply and to participate with Wellmark. If you are eligible based on location, you must also be an eligible contracting provider type. If you are an eligible contracting provider type, and:

  • If the answer is "yes" to at least one network below, you may apply and provide services after your effective date. You may also participate in that particular network(s).
  • If the answer is "no" for any network, you are not eligible to participate in that network.
  • If the answer is "no" to each of the networks, you are not eligible to apply or participate.

Note: Independent Clinical Laboratories, Durable/Home Medical Equipment Suppliers and Orthotic and Prosthetic Suppliers do not have to be physically located in South Dakota or in a county bordering to South Dakota to participate in Wellmark's Indemnity, PPO, TPA, and HMO networks.  See the ancillary claims information regarding claims filing rules for these provider types. Continue the enrollment process in Step 2.
