Oklahoma health insurance for 2027
Oklahoma residents buy marketplace coverage through HealthCare.gov, a state-based exchange that uses the HealthCare.gov platform. Open enrollment for 2027 runs November 1, 2026 to January 15, 2027, and a plan picked by December 15, 2026 starts January 1. Oklahoma expanded Medicaid, so adults qualify up to $22,025 a year for one person.
| Where to enroll | HealthCare.gov |
|---|---|
| 2027 open enrollment | November 1, 2026 to January 15, 2027 |
| Last day for Jan 1 coverage | December 15, 2026 |
| Medicaid expansion | Yes |
| State coverage mandate | No |
| Short-term plans | Allowed. A 2024 federal rule limits them to 4 months in total, but federal agencies said in August 2025 they would not enforce it while they rewrite it, so state law sets the limits |
What a plan costs in Oklahoma
In Pushmataha County, the median-priced county in Oklahoma, the benchmark silver plan cost a 40-year-old $592 a month in 2026. Across 77 counties it ran from $564 (Tulsa) to $818 (Cimarron, Coal and 3 other counties). 2027 prices will be different.
A single 40-year-old in Pushmataha earning $39,900 (250% of the poverty line) would get about $304 a month in 2027 credit against that price. At 60 the same plan is priced near $1,258, and the credit grows to about $970, because the amount you're expected to pay depends on income, not age.
