Oklahoma Attorney General Gentner Drummond has filed a civil lawsuit accusing the Neuropathy Treatment Clinic of Oklahoma and its owner of running a multi‑year scheme to bill Medicaid for services the state says were not medically necessary or covered. According to the complaint, the clinic re‑coded device and injection treatments and billed for larger drug doses than were actually administered, generating roughly $1 million in improper SoonerCare payments. The filing asks the court to claw back the money and hit the defendants with civil penalties.
State files suit in Oklahoma County
The attorney general’s office filed a 21‑page petition on March 26, 2026, naming Neuropathy Treatment Clinic of Oklahoma, LLC and James Warren Linn Jr. as defendants. Prosecutors say the alleged scheme ran from August 2021 through August 2025 and targeted SoonerCare reimbursements. Details of the filing were reported by KOKH.
Clinic locations and patient access
The clinic has operated locations in Tulsa and Oklahoma City. Its public website lists an office at 4636 S. Harvard Ave in Tulsa and another at 6001 NW 139th St. in Oklahoma City, along with patient phone numbers, referral and billing fax lines, and appointment links. Those addresses and contact details appear as listed on the Neuropathy Treatment Clinic of Oklahoma website.
Billing consultant named in the complaint
Drummond’s petition also names Michael Evans as a billing consultant the state says worked with the clinic on coding and dose representations. The National Billing Institute’s website lists Michael Evans as the company’s owner and managing member, a background the complaint points to in laying out its allegations. The state characterizes his role as part of a broader civil effort to recover taxpayer funds rather than an immediate criminal indictment.
How prosecutors say the billing worked
According to the lawsuit, the defendants used Sanexas nerve‑stimulation treatments, which Oklahoma Medicaid does not cover, then re‑coded those visits as physical therapy in order to obtain payments. The complaint further alleges the clinic bought 1‑gram vials of Carnitor (levocarnitine), diluted them into a roughly 90% saline “Carnitor Blend,” and administered small aliquots while billing as if full‑gram doses had been given.
The filing says staff spread tiny amounts of the blended drug across multiple injection sites so the clinic could claim multiple billing units per patient visit. It also cites insurer denials and warnings about overpayments that preceded the state’s action. Billing totals and specific examples are laid out in the petition, which is posted by KOKH.
Legal claims and enforcement context
The state is proceeding under Oklahoma’s Medicaid False Claims framework and is asking the court for restitution, treble damages, and per‑claim civil penalties, along with a jury trial. If the state prevails, the clinic and its owner could face repayment of SoonerCare funds, statutory penalties and costs, and possible administrative fallout such as exclusion from Medicaid programs.
The suit tracks with a series of recent enforcement actions by the attorney general’s Medicaid fraud unit. For context on the office’s recent recoveries, see a March 2026 Oklahoma Attorney General announcement involving a separate settlement…
