Prior Authorization

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. The Procedure Code Look Up Tool will also specify if the authorization request should be directed to the specialized Service Determination team. If Service Determination is not indicated, the requested service will be reviewed by Utilization Management. 

Prior Authorization Procedures

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

Other services, including Home and Community Based Services (HCBS)/Waiver, Personal Care, ABA, and outpatient services, currently require providers to submit authorization requests via fax or email.**

The following is a list of available Prior Authorizations Forms:

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

  • Fax: 937-396-3901
  • Mail: CareSource PASSE
    Attn: Utilization Management Dept.
    P.O. Box 1598
    Dayton, OH 45401-1598

**Any changes to the Prior Authorization process will be communicated on our Updates & Announcements Page.
