What is the Colorado Prior Authorization Request Program?

Acentra administers the Department of Health Care Policy & Financing (the Department) fee-for-service Utilization Management (UM) program for select outpatient benefits, services, supplies, out-of-state inpatient hospital services, the Inpatient Hospital Review Program (IHRP), and select Physician Administered Drugs (PADs) under the umbrella of ColoradoPAR Program.

Through a competitive Invitation to Negotiate process, the Department selected Acentra (formerly Kepro) to administer the fee-for-service UM program for outpatient benefits, services and supplies, out-of-state inpatient services and the Inpatient Hospital Review Program, under the umbrella of the ColoradoPAR program.
