Colorado Medicaid covered approximately 1.19-1.20M people. Two independent sources give close but different-period figures for total Colorado Medicaid/CHIP enrollment: KFF's state indicator (1,188,091, May 2026) and CMS's 2024 Medicaid Managed Care Enrollment and Program Characteristics report (1,197,490 total Medicaid enrollees, July 1, 2024). Consistent with a modest post-pandemic 'unwinding' enrollment decline between mid-2024 and mid-2026, not a data error. Reported as a range rather than a single false-precision number.
Funding & federal match
Colorado has adopted ACA Medicaid expansion, effective 2014-01-01.
For FFY2026 (Oct 1, 2025 - Sep 30, 2026), Colorado's Federal Medical Assistance Percentage (FMAP) is 50%.
Delivery system & managed care
A large share of Colorado Medicaid is delivered through managed care organizations (MCOs) rather than fee-for-service — estimates range from 0.3-0.4% of Medicaid enrollees.
Waivers
Colorado operates Medicaid managed care under the Colorado Substance Use Disorder (SUD) / Health-Related Social Needs (HRSN) Section 1115 Demonstration, a Section 1115 demonstration waiver. Demonstration Project No. 11-W-00336/8, originally approved effective January 1, 2021 through December 31, 2025 to expand the substance use disorder continuum of care. Amended in 2024-25 to add Health-Related Social Needs (HRSN) coverage (housing and nutrition supports) for eligible Health First Colorado and CHP+ members.
