Coverage Information

The following data is provided directly from the CHAMPS Eligibility and Enrollment Subsystem.

Note: DSH related eligibility inquiries are only available to providers enrolled under the FAO enrollment type that have completed the DSH question under the "Manage Provider Checklist" (in the CHAMPS-PE subsystem) and have received approval from MDHHS.

Enrollment Process

  1. Download the MPHI companion guide and determine which services your organization is interested in using.

  2. Enroll as a Provider or Billing Agent in CHAMPS.

  3. Note: Clearinghouse vendors need to enroll as a Billing Agent and be associated with the Providers they represent to be able to submit HIPAA 270/271 transactions on their behalf. For information on how to associate MPHI as a Billing Agent, please click here.

  4. Complete MPHI’s online registration form.

  5. Allow 5-10 business days for MDHHS to review your application. MPHI will contact you with login/password and instructions on how to use our HIPAA 270/271 web-services once your application has been approved.
