Prior Authorization-es

CareSource PASSE™ evaluates prior authorization requests based on medical necessity 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 PASSE should be authorized before the service is delivered. CareSource PASSE is not able to pay claims for services in which prior authorization is required but not obtained by the provider.

Prior Authorization Procedures

The Provider Portal is the preferred and faster method to request prior authorization for health care services. You can receive immediate approval and review the status of an authorization.

Providers can obtain prior authorization for emergency admissions via the Provider Portal, fax or by calling Provider Services at 1-833-230-2100.
