Questions

Good questions, short answers.

When is open enrollment for 2027 coverage in Colorado?

Colorado runs its own exchange, Connect for Health Colorado, which sets its own dates. Most exchanges open Nov 1, 2026 and close Jan 15, 2027 for 2027 coverage; confirm the exact dates with Connect for Health Colorado. A qualifying life event (a move, a new baby, losing other coverage) opens a Special Enrollment Period at other times of year.

Where do I buy health insurance in Colorado?

Colorado residents enroll through Connect for Health Colorado. You can also buy off-Marketplace plans, health sharing, or supplemental coverage directly.

Is Medicaid available in Colorado?

Yes. Because Colorado expanded Medicaid, adults under a certain income may qualify regardless of family status. Eligibility is based on income and household size.

How much does health insurance cost in Colorado?

It depends on your age, county, plan tier, and — most importantly — whether you qualify for a subsidy. Many Colorado enrollees pay well under $100/month after ACA premium tax credits. Use our calculators to estimate your cost.
