Authorization is not a guarantee of payment. Claims payment is subject to Member Eligibility at the time of service and a properly completed claim form in accordance with applicable National Correct Coding Initiative (NCCI) edits, TMPPM requirements, and DHP claims completion requirements posted on our web site.

Member Eligibility: DHP encourages providers to verify eligibility of Medicaid members prior to each service. Eligibility verification is available on the DHP website or on the TMHP website.

In the event that a member is given retroactive eligibility by the Health and Human Services Commission (HHSC), DHP will allow a retroactive authorization for 30 days from the date retroactive eligibility is posted to the TMHP portal. Retroactive authorizations are subject to medical necessity review and all relevant utilization management criteria of DHP.

COB: Some outpatient services/procedure codes may require prior authorization regardless of DHP as secondary payer. Providers should verify authorization requirements utilizing the code look up tool found on this website. In cases where DHP is secondary payer and no prior authorization is required, providers should verify the services are a covered benefit by the primary payer.

Verifying Benefits: It is the Provider’s responsibility to verify the service(s)/procedure code(s) requested is a benefit of Texas Medicaid by utilizing the Texas Medicaid Provider Procedures Manual (TMPPM) and the Texas Medicaid Fee Schedule.

If the service requested is beyond the benefit limit or is not a covered benefit and the provider would still like to submit the request for consideration of medical necessity as a case-by-case benefit exception, the provider should fax the request to the DHP Utilization Management department at the number listed below with a statement on the fax coversheet indicating the requested service is a non-covered benefit or over the benefit limit.

Case by Case Benefit Exceptions: Requests for Case by Case services beyond the benefit limit or which are not a covered benefit may be considered with submission of supporting clinical documentation.
