Prior Authorization

CareSource® evaluates prior authorization requests based on medical necessity, medical appropriateness and benefit limits.

Services That Require Prior Authorization

Please refer to the Procedure Code Lookup Tool to check whether a service requires prior authorization. All services that require prior authorization from CareSource should be authorized before the service is delivered. CareSource is not able to pay claims for services in which prior authorization is required, but not obtained by the provider.
