An investigation by the Oklahoma Attorney General's Medicaid Fraud Control Unit has resulted in 10 arrests, two surrenders, 10 criminal cases, and one major civil action against a Tulsa-area healthcare provider accused of defrauding the state's Medicaid program. The wide-ranging probe, dubbed 'Operation Sooner Shield,' uncovered schemes involving fraudulent billing, exploitation of vulnerable patients, and identity theft.

Why it matters

Medicaid fraud drains critical resources from the state's healthcare system and puts patients at risk. This crackdown demonstrates Oklahoma's commitment to rooting out abuse and holding bad actors accountable, protecting both taxpayer dollars and the wellbeing of Medicaid recipients.

The details

The civil case targets the Neuropathy Treatment Clinic of Oklahoma LLC and its manager, James Warren Linn Jr., alleging they billed Medicaid for medically unnecessary and unapproved treatments, as well as diluted drug injections prescribed to nearly every patient. The criminal charges include neglect of a vulnerable adult and exploitation of the elderly. Authorities coordinated with Medicaid Fraud Control Units in neighboring states as part of the investigation.

  • The alleged fraudulent scheme at the Neuropathy Treatment Clinic of Oklahoma LLC ran from August 2021 through August 2025.
  • The clinic posted a notice of closure on its website on March 25, 2026.
