Cigna Is Leaving the ACA Marketplace: What Its 369,000 Members Should Do for 2027

Cigna is exiting the individual ACA marketplace entirely — all 11 states, roughly 369,000 members — at the end of 2026. If you have a Cigna marketplace plan, your coverage is safe through December 31, but there will be no Cigna option when you shop for January. Here's the timeline, what the discontinuation letter means, and how to land in a replacement plan that actually covers your doctors and prescriptions.

Quick Answer: What Cigna Members Need to Know

Your Cigna plan stays fully in force through December 31, 2026 — nothing changes mid-year. Cigna will not sell individual marketplace plans anywhere in 2027, so you'll need to choose a new insurer during Open Enrollment (November 1 – January 15; enroll by December 15 for January 1 coverage). A discontinuation letter from Cigna is headed to your mailbox this fall. If you do nothing, the marketplace may auto-assign you to a "similar" plan from another company — with a possibly different network, drug list, and price — so compare your options actively instead of accepting the default.

What Cigna Announced

Cigna confirmed it will exit the individual ACA marketplace business completely for plan year 2027. This isn't a county-by-county retreat — it's a full withdrawal from all 11 states where the company sells individual plans:

Arizona, Colorado, Florida, Georgia, Illinois, Indiana
Mississippi, North Carolina, Tennessee, Texas, Virginia
Roughly 369,000 marketplace enrollees affected across those states

Cigna isn't alone. At least a dozen insurers — including Molina, CareSource, Medica, and PacificSource — are exiting or shrinking their marketplace footprint for 2027. But Cigna's is the largest single exit, which is why so many households are getting letters this fall. For the full list, see our guide to insurer exits in 2027.

What This Does NOT Affect

The exit is specific to individual ACA marketplace plans. If you have Cigna coverage through your employer, that's a separate line of business and is not part of this announcement. The same goes for Cigna's Medicare products and dental plans. The people who need to act are those who bought a Cigna plan themselves on HealthCare.gov or a state exchange — including anyone whose plan came through a broker but is billed as an individual marketplace policy.

Your Timeline From Here

Now through October: Watch your mail. Cigna is legally required to send a discontinuation letter explaining that your plan won't be offered in 2027. It's official notice, not a bill or a sales pitch — but don't throw it out.
Late October: Window-shopping typically opens on HealthCare.gov — you can preview 2027 plans and prices in your county before enrollment starts.
November 1: Open Enrollment begins. You can enroll in any plan available in your area — your Cigna exit doesn't limit your choices.
December 15: The deadline that matters. Enroll by this date and your new coverage starts January 1, 2027 — zero gap after your Cigna plan ends December 31.
January 15: Open Enrollment closes in HealthCare.gov states. Enrollments after December 15 generally start February 1, which means a month-long gap after your Cigna coverage ends.

The auto-assignment trap

If you do nothing, the marketplace may "crosswalk" you into a plan from a different insurer that a matching formula considers similar to your Cigna plan. You won't wake up uninsured — but you might wake up in a plan whose network excludes your doctors and whose formulary prices your medications differently. The crosswalk is a safety net, not a recommendation. With Cigna's entire membership being redistributed at once, verify anything you're mapped into — or better, choose for yourself.

How to Pick Your Replacement Plan

Losing a carrier you liked is annoying, but the replacement process is manageable if you work from your own needs instead of the marketplace's default match:

Write down your must-haves first: every doctor, hospital, and prescription in your household. This list — not premium — is your first filter.
Check networks before prices: the carriers remaining in your county (and some new entrants) contract with different providers than Cigna did. A cheap plan that excludes your specialist isn't cheap.
Re-check your subsidy: with Cigna's plans gone, the benchmark plan that sets your premium tax credit may change in your county — your subsidy could be different even if your income isn't.
Compare every carrier, not just the crosswalk match: the formula's pick is rarely the best deal in your county, especially in a year when every insurer repriced.
Enroll by December 15: that's what guarantees your new plan starts the day after your Cigna plan ends.

The Bottom Line

Cigna's exit is big news, but for any individual household it's a solvable problem with a hard deadline. Your coverage runs through December 31 no matter what. Between November 1 and December 15, you choose a replacement — actively, against your own list of doctors and medications — and you start January 1 with no gap. The only losing move is assuming the system will sort it out for you.

Frequently Asked Questions

Is Cigna really leaving the ACA marketplace?

Yes. Cigna has announced it will not offer individual ACA marketplace plans in any state for 2027. That's a complete exit from the individual marketplace business — all 11 states where it currently sells, covering roughly 369,000 enrollees.

Which states are affected by Cigna's exit?

Arizona, Colorado, Florida, Georgia, Illinois, Indiana, Mississippi, North Carolina, Tennessee, Texas, and Virginia — every state where Cigna sells individual marketplace plans.

When does my Cigna marketplace coverage end?

Your current plan stays fully in force through December 31, 2026 — same benefits, same network, same costs. Nothing changes mid-year. The exit affects plan year 2027: there simply won't be a Cigna option when you shop for January coverage.

Does this affect my Cigna plan through work?

No. The exit covers individual ACA marketplace plans only. Employer-sponsored Cigna coverage, Medicare products, dental plans, and other lines of business are not part of this announcement.

What happens if I do nothing?

You won't be left uninsured automatically — HealthCare.gov or your state marketplace may 'crosswalk' you into a plan from a different insurer that a formula considers similar to your Cigna plan. But that replacement can have a different provider network, drug formulary, and price. Treat it as a backstop, not a recommendation.

When can I pick my replacement plan?

Open Enrollment runs November 1, 2026 through January 15, 2027. Enroll by December 15, 2026 for coverage that starts January 1, 2027 with no gap. You'll also receive a discontinuation letter from Cigna this fall — that's your official notice.

Will my doctors take my new plan?

Not automatically. Networks vary by insurer, and the carriers remaining in your county may contract with different hospitals and practices than Cigna did. Before enrolling, check each candidate plan's provider directory for your specific doctors and its formulary for your prescriptions.

Why is Cigna leaving?

The individual marketplace math deteriorated industry-wide: enhanced subsidies expired at the end of 2025, enrollment dropped by millions, and the remaining risk pool is sicker. Rather than raise rates and hope, Cigna chose to exit the individual business entirely — as did Molina (partially), CareSource, Medica, PacificSource, and others. It's a business decision about the market, not about your claims.
