When is Open Enrollment in Colorado for 2026?

Coloradans who are currently uninsured or have recently lost coverage are able to get health insurance that starts the first day of the month following plan selection.

And for others, you can still buy health insurance if you have a life-changing event. Certain events, including moving, getting married, and having a baby all make you eligible for a special enrollment period. Otherwise, almost all Coloradans can buy health insurance during the Open Enrollment period, which begins Nov. 1, 2025 with a plan start date of January 1st, 2026.
