Where Did the Coverage Go? Investigating the Impact of Medicaid Unwinding in Colorado
Over the past year, Colorado has seen a noticeable increase in uninsured patients visiting community clinics.
In partnership with the Colorado Safety Net Collaborative (CSNC), CIVHC began an evaluation data request to understand what happened to more than 500,000 Coloradans who were disenrolled during the Medicaid unwinding. With protections from the COVID-19 public health emergency ending, many residents lost coverage, leaving many wondering where they went.
Did they get insurance through their jobs? Are they still uninsured?
These were the driving questions for a recent evaluation project using the Colorado All-Payer Claims Database (CO APCD). By examining data from 2014 to 2024.The project aimed to identify trends in insurance coverage and gaps in care—especially for those most at risk of falling through the cracks.
CO APCD claims helped track coverage continuity, changes in payer types, and coverage gaps for individuals before and after Medicaid unwinding. Supplemental Medicaid files were also incorporated to gain deeper insights, such as disability identification and qualifying income. This information was then paired with U.S. Census data to understand of self-reported survey uninsured rates.
Why does this matter?
Understanding who lost coverage and why can help clinics, policymakers, and community-based organizations respond with real solutions, whether that’s more targeted outreach, more substantial support for transitions to employer insurance, or improved continuity of care. Without this data, policy decisions risk being built on assumptions rather than reality.
It’s about improving health care for real people and ensuring that everyone in Colorado has a fair shot at staying healthy, getting care when they need it, and avoiding unnecessary trips to the emergency room for issues that could have been treated earlier and more affordably.
