Prior Authorization

Prior Authorization 

The Utilization Management (UM) 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.

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.
