Federal changes are coming to Colorado’s Medicaid program, Health First Colorado. Starting Oct. 1, some immigrants who currently qualify may lose full coverage — but many people will not be affected. If you are, you’ll receive a letter from Health First Colorado before anything changes.
What to do now, before Oct. 1:
◽️ Update your information at Colorado PEAK (co.gov/PEAK), the Health First Colorado app, or your county human services office.
◽️ Use your coverage now — schedule medical, dental, and behavioral health appointments and refill prescriptions.
◽️ Watch for official letters and respond to any you receive.
◽️ Visit or contact Denver Human Services for help reviewing your case. And go to denvergov.org/immigrantsupport for additional community resources.
