Missouri Open Enrollment 2027 for Individuals

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

Short answer

For individuals and couples buying their own coverage 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. A private, medically underwritten plan works on its own clock: if approved, it can start the first of any month, whether or not the window is open.

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.

For 2027 the subsidy line is $63,840 for one person and $86,560 for a couple; above it, every metal level is full price. Bronze and catastrophic plans count as HSA-eligible starting with 2026 coverage, and the 2027 out-of-pocket cap is $12,000 for one person, which is the real worst case to compare.

Missouri this year

Missouri's final 2027 individual average is a moderate 12.3 percent, under the countrywide average, with six insurers filing. That competition is strongest in St. Louis and Kansas City, while the Ozarks, the Bootheel and northern Missouri see fewer choices per county. Both big metros straddle a state line, and most plans there are HMOs built around one hospital system, so a network that stops at the border can be a problem. Missourians enroll through HealthCare.gov, and Missouri layers no reinsurance program or extra state help on top. Earn above $63,840 on your own and you shoulder the full premium.

One thing to do before you choose

St. Louis renters who see doctors in Illinois, and Kansas City residents with specialists on the Kansas side, should confirm that a 2027 plan's directory lists providers in both states before picking on price. Missouri's figures are final, so compare the prices HealthCare.gov now displays, and settle on one by December 15 to have coverage in force on New Year's Day.

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.

The plan I had in St. Louis isn't offered now that I've moved to Springfield. Why?

Missouri insurers do not all sell in every county. Six filed for 2027, but the lineup in Springfield or Joplin can differ from St. Louis. A change of address within the state can also qualify for special enrollment, though open enrollment is running now, so simply compare the plans offered at your new address.

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.
