Step 1: Determine Eligibility

To enroll with Wellmark, you need to be in an eligible location and area of practice as shown below. To provide services that can be considered for benefits, you must first enroll with Wellmark. Wellmark will notify you of your effective date.

After you enroll, 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 enroll and participate with Wellmark. If you are eligible based on location, you must also be an eligible provider type. If you are an eligible provider type, and:

• If the answer is "yes" to at least one network below, you may enroll 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 enroll 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.

• Send Wellmark your participation applications completed for other insurers. Wellmark accepts these applications if:

• The information provided is current.
• The provider has re-signed the certification and release statement.
• A completed Wellmark Addendum is included with the application. The Addendum asks for specific information that Wellmark needs to process your application.

• Provide complete information for faster processing of your application.

• Include your National Provider Identifier (NPI). 
• Answer all questions, putting "N/A" in any blank fields.
• Include your signature and copies of the documents requested in the application.
• Include your agreements if participating in one or more Wellmark networks.

Step 3: Complete Participation Agreements

You can participate with Wellmark by location or through a corporate contract. Wellmark considers a corporation any organization that owns four or more sites of the same type within Iowa or South Dakota.

Wellmark strongly encourages out-of-state independent clinical laboratories and durable medical equipment suppliers to sign both Iowa and South Dakota provider agreements.  Out-of-state providers who sign with Wellmark will be added to the Wellmark provider directories as in-network for both Iowa and South Dakota members.
