How to apply in Colorado
Apply for Health First Colorado online at https://peak.my.site.com/. The portal handles both the initial application and annual renewal. You can also apply by phone at 1-800-221-3943, by mail (download the paper form from the state Medicaid portal), or in person at your county human services / social services office.
Documents you'll need: proof of identity (state ID or passport), Social Security numbers for everyone applying, proof of income for the last 30 days (pay stubs, tax return, unemployment award letter), proof of US citizenship or lawful presence, proof of address (utility bill, lease, piece of official mail), and for pregnancy-related Medicaid, a pregnancy verification letter from a clinician. If you don't have all these documents, apply anyway — state Medicaid programs are required by federal regulation (42 CFR 435.907) to accept applications without documentation and work with you on reasonable compatibility checks.
Language support: every state Medicaid portal must offer interpretation and translation at no cost under Title VI of the Civil Rights Act. Ask for an interpreter when you call or, for written translations, request them in writing. If the state denies reasonable language access, you can file a complaint with the HHS Office for Civil Rights.
Average processing time: the federal standard under 42 CFR 435.912 is 45 days for non-disability applications and 90 days for disability-based applications.
