Missouri Open Enrollment 2027 for Marketplace Renewals

Last updated November 3, 2026 · By Frank Caballero, licensed health insurance broker

Short answer

For people renewing a Marketplace plan in Missouri, open enrollment for 2027 coverage runs November 1, 2026 to January 15, 2027 on HealthCare.gov, and December 15 is the date to choose by for a January 1 start. Before you let the renewal go through, know that a private, medically underwritten plan is another option: if approved, it can start the first of any month.

What 2027 looks like for you

Missouri's average 2027 rate change is 12.3% (finalized). The details are on the Missouri 2027 premium increase page.

Unless you act, HealthCare.gov renews most enrollees into the same plan, or a similar one if yours is gone, at the 2027 price. Your renewal notice shows the new premium, deductible and any change in subsidy. Plans picked during open enrollment replace the renewal, and the 2027 out-of-pocket cap rises to $12,000 for one person.

Missouri this year

Both of Missouri's big metros straddle a state line. Kansas City spills into Kansas and St. Louis into Illinois, so a 2027 plan whose network stops at the border can leave a family's doctors out. Six insurers filed for 2027, and the final average increase is about 12.3 percent. Most metro plans are HMOs built around one hospital system, and choice thins quickly in the Ozarks and the Bootheel. Owner-operators on I-70 and I-44, Springfield real estate agents and cattle families above the subsidy line pay full price. Missourians renew on HealthCare.gov.

One thing to do before you choose

St. Louis families with doctors in the Metro East, and Kansas City families who cross into Johnson County, should use the provider search on each 2027 plan with the out-of-state address entered. Then compare silver and gold side by side, because with six insurers the spread between plans can be wide. If you were healthy all year and your earnings are above the line, I can quote a private PPO too. Approval depends on your health answers, it is not an ACA Marketplace plan, and benefits vary by plan.

Private plan or Marketplace?

Private plan

Healthy and facing a big renewal: priced on age, ZIP code and health. Approval depends on health answers; not an ACA Marketplace plan.

Marketplace

Ongoing treatment, or a subsidy you still qualify for: stay with HealthCare.gov, but pick the 2027 plan yourself instead of auto-renewing.

Questions

When is the 2027 open enrollment deadline in Missouri?

January 15, 2027 on HealthCare.gov. Choose by December 15, 2026 for coverage that starts January 1; plans picked after that start February 1.

I have rheumatoid arthritis and take a specialty drug. What should I check on my Missouri renewal?

Look up the exact drug in the 2027 formulary for your plan, note its tier and whether it needs prior authorization, and confirm your rheumatologist is in-network. If anything changed, compare other plans before December 15. Stay on the Marketplace either way; it covers pre-existing conditions without asking health questions.

Can I get a private plan in Missouri after open enrollment closes?

Yes. You can apply in any month and, if approved, a private plan can start the first of a month; the insurer can decline based on health answers.
