PBT Provider Type Transition-Important information! Acentra is encouraging all providers who are in the process of changing the provider type from Provider Type 25 as instructed via the June Bulletin-please follow this instruction guide to ensure their PARs are processed in a timely manner. There will be delays in getting every PAR transitioned, and we encourage all providers to follow these steps diligently to help decrease the delays as much as possible.
The Go-Live for Prior Authorization Requests (PARs) of Long Term Home Health (LTHH) Registered Nurses (RNs) and Certified Nursing Assistant (CNA) Services is August 1, 2025. There will be an additional step needed to meet the PAR requirements for LTHH Certified Nursing Assistant (CNA), LTHH Registered Nurse (RN) and Private Duty Nursing (PDN). Visit the Nurse Assessor webpage for more information.
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. For additional information, please review the Provider Manual.
