Start the contracting application and credentials verification processes.

Here's how:

  • Check our credentialing guidelines to make sure you meet our requirements.
  • Follow the credentialing steps we outline so we can review and approve your credentials as part of your enrollment with us.
    Note: Physicians and licensed practitioners use CAQH ProViewTM, the universal provider datasource for credentialing. We'll need you to authorize our access to your profile in CAQH ProView.
  • Submit a contracting form. Be sure to select the right one for your provider type.

The contracting application and credentialing verifying processes take place at the same time.

Step Get a contract. Read, sign, and return one copy. You'll keep one copy for your records.
Step Get your credentialing decision and welcome letter.

Your welcome letter tells you:

  • the effective date of your participation with us
  • the products you are enrolled in
  • how to up direct deposit with PaySpan, the vendor we use for electronic payments and remittances.
