Missed Open Enrollment in Colorado? Your Options + 2027 Dates

Quick answer: If you missed open enrollment in Colorado, you can still get ACA health insurance through a 60-day Special Enrollment Period if you have a qualifying life event (job loss, marriage, a baby, a move, and more). If you don’t, you can apply for Health First Colorado (Medicaid) or CHP+ any time of year, and use supplemental plans to limit your risk until the next Open Enrollment, which runs November 1, 2026 to January 15, 2027 for 2027 coverage.

Every year we hear from Coloradans who missed the deadline, got a surprise medical bill, or found out their plan is going away. The good news: missing Open Enrollment is rarely the end of the road. This guide covers the exact dates, who qualifies to enroll right now, what to do if you don’t qualify, and how a free local broker can help.

When is open enrollment in Colorado for 2027?

Colorado runs its own marketplace, Connect for Health Colorado, and has confirmed that the traditional schedule stays in place for plan year 2027:

Outside of that window, most people can only enroll in or change an individual or family plan if they qualify for a Special Enrollment Period.

Can I still get health insurance if I missed open enrollment in Colorado?

Yes, in three situations:

1. You had a qualifying life event in the last 60 days, which opens a Special Enrollment Period.
2. Your household income qualifies for Health First Colorado (Medicaid) or Child Health Plan Plus (CHP+), which enroll year-round.
3. You are a member of a federally recognized tribe, which allows year-round marketplace enrollment.

If none of those apply, skip to what to do if you don’t qualify.

What is a Special Enrollment Period (SEP)?

A Special Enrollment Period is a 60-day window, triggered by a qualifying life event, during which you can buy or change an ACA-compliant plan outside of Open Enrollment. Plans available during an SEP are the same Bronze, Silver, Gold and Platinum plans sold during Open Enrollment, with the same premium tax credits and cost-sharing reductions if you qualify. The 60 days usually count from the date of the event, so acting quickly matters.

Which life events qualify you for special enrollment in Colorado?

Connect for Health Colorado recognizes these qualifying life change events (the list is not exhaustive):

Loss of health coverage

• You lost health insurance from your job (voluntarily quitting still counts as loss of coverage)
• You no longer qualify for Health First Colorado (Medicaid) or CHP+
• You turned 26 and aged off a parent’s plan
• Your student health plan ended
• Your COBRA subsidy ended, or your COBRA coverage ran out
• Your insurer is leaving the market (for example, Cigna customers losing coverage at the end of 2026 qualify for an SEP through March 1, 2027)

Family changes

• Marriage or divorce
• Birth, adoption, or placement of a child for foster care
• Pregnancy certified by a health care provider (a Colorado-specific event)
• Death of a household member enrolled in your marketplace plan

Moves and residency

• Moving to Colorado from another state
• Moving to a new permanent address within Colorado where different plans are available
• Release from incarceration
• Gaining lawful presence in the United States

Income changes (current enrollees)

If you already have a marketplace plan, an income change that makes you newly eligible (or ineligible) for the premium tax credit or cost-sharing reductions can open an SEP to switch plans.

Two deadlines to remember: report household, income or address changes within 30 days, and enroll within 60 days of the event. Your insurer may ask for proof, such as a termination letter, marriage certificate or birth certificate.

Other ways to enroll year-round in Colorado

• Health First Colorado (Medicaid) and CHP+: free or low-cost coverage for Coloradans who meet the monthly income limits. There is no enrollment deadline; apply any time through Colorado PEAK.
• Tax Time Enrollment: check the box on your Colorado state tax return by April 15 and Connect for Health Colorado will open a Special Enrollment Period for you if you’re eligible.
• Native Americans: members of federally recognized tribes can enroll through the marketplace any month of the year.
• Employer coverage: starting a new job with benefits, or your spouse’s employer plan during its own annual enrollment.

What if I don’t qualify for a Special Enrollment Period?

First, know what is not available: short-term health insurance is not sold in Colorado. State rules adopted in 2019 require short-term plans to meet ACA-style benefit standards, and no carrier offers them here. Be wary of any website quoting you a “temporary” Colorado plan.

What you can do is reduce your financial exposure until November 1 with supplemental products that enroll year-round. None of these replace major medical insurance, but they can keep one accident or diagnosis from turning into a large bill:

• Accident insurance: pays a lump sum toward ER visits, fractures, and other injury-related costs.
• Critical illness insurance: pays cash on diagnosis of covered conditions such as cancer, heart attack or stroke.
• Fixed indemnity (hospital) plans: pay a set dollar amount per doctor visit, hospital day or procedure.
• Disability insurance: replaces part of your income if an illness or injury keeps you from working.
• Dental and vision insurance: can be purchased any time; we offer Delta Dental plans directly.
• Health care sharing programs: membership-based cost sharing, not insurance. They can be affordable for healthy people but typically limit pre-existing conditions and are not regulated like insurance, so read the guidelines carefully.

Also mark your calendar: for 2027 coverage, enroll between November 1 and December 15, 2026 so your plan starts January 1.

What’s changing for 2027 Colorado health plans?

• Cigna is leaving Colorado’s individual market. Current Cigna members keep coverage through December 31, 2026 and need to pick a new carrier for 2027.
• Colorado Access is joining the marketplace with plans in select counties for 2027.
• Renewals happen earlier. Eligible customers will be auto-renewed before November 1, so review your renewal notice rather than assuming your current plan is still the best fit.
• Premiums are rising and subsidies are smaller than in 2021–2025, which makes comparing plans, and checking Colorado Premium Assistance eligibility, more important than ever.

Frequently asked questions

When does open enrollment start in Colorado for 2027?

Open Enrollment for 2027 plans starts November 1, 2026 and ends January 15, 2027. Enroll by December 15, 2026 for a January 1 start date.

How long is the Special Enrollment Period in Colorado?

60 days from the qualifying life event. Report the change within 30 days and enroll before the 60 days end.

Does quitting my job count as a qualifying life event?

Yes. Losing job-based coverage qualifies whether you left voluntarily or were laid off. Losing coverage because you stopped paying premiums does not.

Can I buy short-term health insurance in Colorado?

No. No insurer currently sells short-term medical plans in Colorado because of state benefit requirements adopted in 2019. Accident, critical illness and fixed indemnity plans are the main year-round alternatives.

Is there a penalty for not having health insurance in Colorado?

No. The federal penalty was reduced to $0 in 2019 and Colorado has no state-level mandate. The real cost is paying full price for medical care until you can enroll.

Can I apply for Health First Colorado (Medicaid) after open enrollment?

Yes. Health First Colorado and CHP+ accept applications every day of the year. Eligibility depends on household size and monthly income.

Does it cost more to use a broker than to enroll on my own?

No. Premiums are identical whether you enroll directly through Connect for Health Colorado or through a certified broker. Broker compensation is built into the carrier’s rates.
