Where Cox HealthPlans Is Leaving the Marketplace
Cox HealthPlans sells only in southwest Missouri:
| State | Where to enroll | Key deadline |
|---|---|---|
| Missouri | HealthCare.gov | Enroll by December 15 for January 1. Open enrollment ends January 15 |
When Your Cox HealthPlans Plan Ends
Your Cox HealthPlans Marketplace plan stays in place through December 31, 2026. Cox will not sell plans on HealthCare.gov for 2027.
Cox will still sell individual plans directly, off the exchange, in seven counties. Those plans are full price. Premium tax credits are only available on Marketplace plans bought through HealthCare.gov.
What You Need to Do Now
If you get a subsidy now, pick a Marketplace plan on HealthCare.gov by December 15 so you keep it. If you do not get a subsidy, compare an off-exchange Cox plan with Marketplace plans before you decide.
We compare every Marketplace insurer in your ZIP code, check your subsidy and handle the switch at no cost to you. Call 888-730-6031 or request a free quote.
Your Replacement Options
- Oscar and CoxHealth: New Oscar Marketplace plans built with CoxHealth are offered in eight Missouri counties for 2027.
- Other Missouri insurers: Ambetter, Anthem, Blue Cross and Blue Shield of Kansas City, Oscar and UnitedHealthcare all sell Marketplace plans for 2027. See our Missouri open enrollment guide.
Key 2027 Deadlines
| Date | What it means |
|---|---|
| November 1, 2026 | Open enrollment opens |
| December 15, 2026 | Last day to pick a plan for January 1 coverage on HealthCare.gov |
| December 31, 2026 | Your current plan ends |
| January 15, 2027 | Open enrollment ends. Plans picked after December 15 start February 1 |
Losing coverage because your insurer leaves may also qualify you for a special enrollment period, but do not wait. Picking a plan during open enrollment is the only way to avoid a gap.
Do Not Forget Dental, Vision and Extras
If your Cox HealthPlans plan included or was paired with dental, vision or supplemental benefits, check whether those end too. You can add dental insurance, vision insurance or hospital indemnity coverage to a new plan.
If Your Insurer Is Leaving, You Are Not Alone
At least a dozen insurers announced Marketplace exits for 2027, according to healthinsurance.org, including Cigna in 11 states. Rising costs and the end of the enhanced federal subsidies are the main reasons. See our guides to Cigna leaving the Marketplace and what to do when your insurer leaves.
For Missouri dates, insurers and rate changes, see our Missouri open enrollment guide and our guide to Medica leaving the Marketplace, which affects the Kansas City area.
