Prior Authorization

Prior Authorization 

In support of House Bill 3459 and our participating providers, CHRISTUS Health Plan is pleased to announce  that effective July 1, 2022, the prior authorization requirements have been updated for Texas and Louisiana Health Exchange, Texas and New Mexico Medicare Advantage, Commercial and Uniformed Services Family Health Plan. 

The following types of services require Prior Authorization: 

   o All listed services on the NCHD Prior Authorization list
   o All ABA Providers (All Services for Autism)
   o All Out-Of-Network (OON) Services and Providers, including those who are contracted but not been fully credentialed

Note: If the requirements for prior authorization are not followed, CHRISTUS Health Plan may not pay for the services. In most cases, physicians and other providers will be responsible for getting the prior authorization from the health plan. We have instructions and procedures in place for providers to request prior authorization. 

The clinical department will evaluate the request to assess the Medical Necessity and coverage of proposed treatment. CHRISTUS Health Plan will also check that the treatment is being provided at the appropriate level of care. Prior authorizations are approved or denied based on current evidence- based clinical standards of care and guidelines and not on incentives or bonus structures. The member and provider will receive notification of CHRISTUS Health Plan’s decision, whether approved or denied. 

The following types of services require provider notification via the Notification form (below): 

  • Transplant Services
  • Hemo Dialysis Services

The Prior Authorization lists for each specific line of business is below have been updated (below) to reflect these changes. Please remove any previous versions of the Prior Authorization list from your reference materials.
