Where Duncan Regional Hospital is
One facility, taken from the CMS Hospital General Information file, updated 22 July 2026. Listing a hospital is not a statement about which plans contract with it — that is decided plan by plan.

Why no page can promise your plan covers Duncan Regional Hospital
Hospital networks are set plan by plan and renegotiated during the year. Two plans from the same insurer, at similar prices, can differ on whether a hospital is in network. Nothing in the public CMS files records hospital contracts, so any page listing "insurers Duncan Regional Hospital accepts" is describing one plan on one day, and not saying which.
What is knowable is the shape of the market: 3 insurers file 28 plans across Stephens County, and some plans in Stephens County are PPOs, which pay something out of network; the rest (HMO) generally do not.
Three checks settle it for your own plan: the insurer’s own provider directory for the exact plan name, the hospital’s billing office (ask about the plan, not the carrier), and the date you checked, because the answer can change mid-year.

Open Enrollment 2027
Medica and Mending Health are leaving Oklahoma's marketplace for 2027, and Open Enrollment runs 1 November 2026 to 15 January 2027. If your 2026 plan is from them, the plan that replaces it is a different plan with its own network. I can check Duncan Regional Hospital, and any doctors you name, against the plans filed in your county and send you the ones that include them, with the date I checked.
Emergency care is treated differently
1 of these location run an emergency room. Federal law requires marketplace plans to cover emergency care at in-network cost sharing even when the hospital is out of network, so an emergency visit is not the case to worry about. Planned surgery, imaging, maternity and specialist follow-up are where the network matters.
