Summary
Colorado's Medicaid program (Health First Colorado) has implemented multiple updates including mandatory provider revalidation with claims denial starting January 1, 2025, expanded coverage for children and pregnant people regardless of immigration status, and various billing and coverage changes across specialties. Providers who fail to revalidate by their due date will have claims denied and must resubmit them after completing revalidation.
Action Required
Immediately: Check provider revalidation status on the Department's Revalidation web page and complete revalidation by listed due date to avoid claim denials starting January 1, 2025. Resubmit any denied claims after completing late revalidation. Update billing systems to prepare for increased patient volume from expanded coverage for children and pregnant people regardless of immigration status. Review EPSDT benefits for comprehensive coverage of medically necessary services for members under age 21.
