Louisville medical professionals among defendants in federal health care fraud crackdown

Four Louisville-area defendants, including a physician and a nurse, are among those charged in a nationwide, multi-case federal health care fraud crackdown—the 2026 National Health Care Fraud Takedown that charged 455 people with over $6.5 billion in false claims. In Louisville, Angela Renfro and Briana Gosnell (KLF Company LLC and Freedom Center LLC) allegedly submitted more than $11 million in Medicaid claims for peer-support and psychoeducation services using providers’ NPI numbers without authorization. Dr. Christian Berkhahn is charged with conspiracy to obtain controlled substances and health care fraud for prescriptions written under others' names; nurse Meredith Douglass is accused of stealing medications and falsifying records to obtain fentanyl and other Schedule II drugs. A fourth defendant, Einar Serrano Reyes, allegedly used a Louisville location to bill Medicare for over $450,000 for services never provided. Prosecutors say the schemes diverted funds from programs for vulnerable patients; defendants are presumed innocent unless proven guilty.
