Preparing for Accountable Care Collaborative: Phase III

Featured Announcements

RAE Region Map
Over the past six months, HCPF has held 20 meetings with more than 1,000 attendees to discuss six possible Regional Accountable Entity (RAE) maps for Phase III. After careful consideration of the available data and stakeholder feedback, HCPF has made the final determination to move forward with the four-region map proposed in the Concept Paper for ACC Phase III. More information about this decision is detailed in the ACC Phase III RAE Region Fact Sheet.

We are thrilled to have received such robust feedback on the proposals in the Concept Paper and we are continuing to synthesize and incorporate insights into the ACC Phase III draft request for proposal (RFP). To ensure we are taking the time required to do this thoughtfully, we will be releasing the draft RFP by the end of January 2024. There will be additional presentations and opportunities to share your thoughts on the draft RFP once it is available.

Opportunities to Provide Feedback


The Department of Health Care Policy & Financing (HCPF) created the Accountable Care Collaborative (ACC) in 2011 to deliver cost-effective, quality health care services to its Colorado Medicaid members and to improve the health of Coloradans. The ACC features Regional Accountable Entities (RAEs) operating in seven regions.

Current contracts between HCPF and the RAEs will end on June 30, 2025. HCPF has developed goals and priority areas for improvement and innovation intended to better align with our modernized mission, advances made by our sister agencies, and stakeholder input received over the past several years.
