Medicaid in Oklahoma
Oklahoma expanded Medicaid (SoonerCare) effective July 1, 2021, after voters approved State Question 802 with 50.5% of the vote. The expansion covers adults aged 19 to 64 with household incomes up to 138% FPL (about $22,025 for a single person, or $45,540 for a family of four, for 2027 coverage). Over 300,000 Oklahomans have enrolled through expansion, making it one of the larger recent expansion states by enrollment.
Before expansion, Oklahoma had one of the highest uninsured rates in the country. Childless adults had no Medicaid option, and parents qualified only at very low income levels (around 42% FPL). The expansion was particularly impactful in rural Oklahoma, where uninsured rates were the highest.
Oklahoma's uninsured rate has dropped to approximately 10% since expansion, down from about 14% before. Roughly 400,000 Oklahomans still lack coverage, many of whom are eligible for either Medicaid or marketplace subsidies but have not enrolled.
New federal work requirements apply to expansion adults. States must start them by January 1, 2027 (a state making a good-faith effort can get extra time). Most expansion enrollees ages 19 to 64 will need to show 80 hours a month of work, school, job training, or community service. Parents of children under 14, pregnant people, people who are disabled or medically frail, American Indians, and some others are exempt. Watch for notices from the Oklahoma Health Care Authority.
Where Oklahomans enroll for 2027
Oklahoma moved to a state-based exchange on the federal platform, but nothing changes for shoppers this year: you still apply and enroll on HealthCare.gov for 2027 coverage. The Oklahoma Insurance Department plans to launch the state's own exchange for the 2028 coverage year, with shopping on the new site starting in November 2027. Enroll by December 15, 2026 for coverage that starts January 1, 2027. If you enroll between December 16 and January 15, coverage starts February 1.
What plans cost in 2027
Premiums rose again for 2027 and vary significantly by region. Here is the benchmark (second-lowest cost Silver) premium for a 40-year-old before subsidies, from HealthCare.gov plan data:
- Oklahoma County (Oklahoma City): about $624 per month, up from $561 in 2026
- Tulsa County: about $620, up from $564
- Comanche County (Lawton): about $755, up from $656
- Pittsburg County (McAlester): about $775, up from $636
- Texas County (Guymon) and Woodward County: about $872, up from $818 and $777
About 262,000 Oklahomans picked a marketplace plan during 2026 open enrollment, according to CMS. The enhanced subsidies expired after 2025 and were not renewed, so for 2027 there is no premium tax credit above 400% FPL ($63,840 for a single person, $86,560 for a family of two). Oklahoma's relatively low median income means a large share of enrollees relied heavily on the enhanced credits.
Carriers in Oklahoma (2027)
Five insurers offer individual marketplace plans in Oklahoma for 2027. Medica and Mending Health, which sold plans in 2026, left the marketplace, so their enrollees need to pick a new plan during open enrollment:
- Blue Cross and Blue Shield of Oklahoma is the dominant carrier and the only one offering plans in all 77 counties for 2027. BCBSOK has the broadest provider network in the state.
- UnitedHealthcare sells plans in 57 counties for 2027, including Oklahoma City, Tulsa, and many rural counties.
- Ambetter of Oklahoma (Centene) sells plans in 43 counties and often competes on price with narrower networks.
- CommunityCare sells plans in 27 counties for 2027, including Tulsa, Oklahoma City, and parts of eastern Oklahoma. CommunityCare is a Tulsa-based health plan with deep roots in the local healthcare community. Their network includes major Tulsa hospitals like St. Francis Health System and Hillcrest Medical Center.
- Oscar Health sells plans in 12 counties, including the Oklahoma City and Tulsa metros.
Oklahoma and Tulsa counties have all five insurers. Many rural counties have two or three, and seven counties, including Texas County in the panhandle, have only BCBS.
Key regions
Oklahoma City metro
Oklahoma County and surrounding areas are the largest population center. OU Health (University of Oklahoma Medical Center), INTEGRIS Health, SSM Health St. Anthony, and Mercy Hospital are the major systems. All five marketplace insurers sell plans in Oklahoma County for 2027, and premiums in the OKC metro tend to be among the lowest in Oklahoma.
Tulsa metro
Tulsa County has all five marketplace insurers for 2027, including the local CommunityCare plan. St. Francis Health System, Hillcrest Medical Center, and Saint John Medical Center are the anchor hospitals. The Tulsa area has strong competition and generally competitive premiums.
Rural southeastern Oklahoma
This region has among the highest uninsured rates and worst health outcomes in the state. Hospital closures have been a serious problem, with several rural facilities shutting down in recent years. Choctaw Nation Health Services and other tribal health systems provide critical care in this area. Many counties here have only two marketplace insurers for 2027 (BCBS plus UnitedHealthcare, CommunityCare, or Ambetter, depending on the county), and premiums can be significantly higher than in metro areas.
Western Oklahoma and the panhandle
Sparsely populated with limited healthcare infrastructure. Some counties, like Woodward, have BCBS and UnitedHealthcare for 2027. Others, like Texas County, have only BCBS. Residents may need to travel to Oklahoma City or Amarillo, TX for specialty care. Premiums here reflect the high per-capita cost of serving a dispersed population.

Oklahoma-specific things to know
Medicaid expansion made a big difference.Oklahoma's expansion eliminated the coverage gap and brought the uninsured rate down significantly. If you earn under 138% FPL, check SoonerCare eligibility before shopping on the marketplace. Medicaid has no premiums and minimal cost-sharing.
Tribal health resources. Oklahoma has one of the largest Native American populations in the country, with 39 tribal nations. Tribal members can access Indian Health Service (IHS) and tribal health facilities. Native Americans also qualify for special ACA provisions: cost-sharing reductions at all income levels and monthly special enrollment periods.
Rural hospital closures affect network adequacy. If you live in rural Oklahoma, verify that your plan has in-network providers within a reasonable distance. Some plans may meet the letter of network adequacy standards but still require significant travel for specialty care.
