The annual open enrollment period for 2027 health insurance plans in Colorado begins on Nov. 1. Residents can secure coverage by using the Connect for Health Colorado platform throughout the enrollment window.

Selecting a plan during this window allows residents to maintain continuous health coverage for the coming year. Understanding these enrollment timelines ensures that households can manage their medical costs and insurance access effectively.

The enrollment window spans from Nov. 1 to Jan. 15, 2027, with plan selection deadlines determining coverage start dates. Households that enroll by Dec. 15 will see coverage begin on Jan. 1, 2027, while those enrolling later will see coverage start on Feb. 1.

The players

The state-based health insurance marketplace where residents shop for and enroll in individual health coverage plans.

Thrive Community Health Network

A local network providing community support and hosting open houses to help residents navigate insurance enrollment.

The details

Coloradans who purchase their own insurance must navigate the Connect for Health Colorado platform to review and select their 2027 plans. The date of plan selection dictates when the policy becomes active, with a mid-December cutoff for those wanting coverage to begin on the first of the year. The Thrive Community Health Network is also hosting open houses to assist residents with the enrollment process.

Residents should review their current health insurance plans before Nov. 1 to identify potential changes in coverage or household premiums. If you have questions about which plan best fits your budget, discuss your specific needs with a licensed insurance professional or tax advisor.

The takeaway

The open enrollment period is the primary window to secure health coverage for 2027. Mark your calendar for the Dec. 15 deadline if you want your new coverage to take effect on Jan. 1.
