Outpatient Hospital Payment

Enhanced Ambulatory Patient Groups (EAPG)

The Department of Health Care Policy & Financing (the Department) implemented the Enhanced Ambulatory Patient Grouping System for October 31, 2016. Enhanced Ambulatory Patient Groups (EAPG) weight tables are provided for reference by various healthcare partners and providers. The relative weight tables are used by the Department to reimburse hospitals for outpatient services. The Department has compiled a list of Frequently Asked Questions for providers and for Health First Colorado members regarding the implementation.

Documentation for historical weight and base rate information is available upon request. Please email HCPF_Hospitalregulatory@state.co.us

Billed Amount Redistribution Logic

The Department has worked with 3M on updating the lower of pricing logic which compares EAPG payment to line item submitted charges. This update, which will be effective October 31, 2016 and was released as part of 3M's October 12, 2017 service pack release, will utilize the EAPG grouper to redistribute billed amounts by visit prior to the lower of pricing comparison between EAPG payment and line item submitted charges. This change will make payments under the EAPG methodology more in alignment with initial payment projections. See below for an attachment providing greater detail for this update.

EAPG Billed Amount Redistribution

For any questions regarding the billed amount redistribution logic, please email HCPF_Hospitalregulatory@state.co.us.


Hospitals will not be required to purchase the EAPG software to facilitate the implementation of EAPGs. The EAPG grouper specific to Colorado Medicaid will assign the EAPGs to the claim lines and calculate the payment within the Department's MMIS system. Hospitals may choose to purchase the EAPG grouping software allowing them to project revenue. For sales inquiries, please contact 3M Health Information System.
