Does Medicaid Cover ABA Therapy in Colorado?

Published April 8, 2026

Yes — Health First Colorado (Colorado's Medicaid program) covers ABA therapy for children and teens under 21 with an autism diagnosis. Colorado has a growing ABA provider network concentrated in the Denver metro area, and a commercial insurance mandate that covers children through age 18. Here's how to access coverage.

Health First Colorado managed care plans

Health First Colorado delivers services through Regional Accountable Entities (RAEs) that manage physical and behavioral health. Major plans covering ABA therapy include:

• Denver Health Medical Plan — Denver County
• Rocky Mountain Health Plans — western slope and statewide
• Anthem BlueCross BlueShield of Colorado — statewide
• Centura Health at Home / Colorado Access — metro Denver and eastern Colorado
• Aetna Better Health of Colorado — statewide

Colorado's autism insurance mandate

Colorado law (HB 10-1204) requires fully-insured commercial health plans to cover ABA therapy for children under age 19. Coverage includes assessment, treatment, and family training. If your child has private insurance, they are entitled to ABA coverage under Colorado law.
