Lawton-Area Trio Sentenced to Serve More Than 12 Years Collectively in Federal Prison for Health Care Fraud

US Attorney's Office, Western District of Oklahoma, April 22, 2025

OKLAHOMA CITY – JIMMIE MATHEWS, 41, NATHAN MATHEWS, 42, and AMBER DELGER, 55, all of the Lawton area, have been sentenced for their roles in a conspiracy to commit health care fraud, announced U.S. Attorney Robert J. Troester.

The defendants were each charged in May 2024, with Delger being charged by Information with conspiring to commit health care fraud, and both Jimmie and Nathan charged by a 16-count federal grand jury Indictment with conspiring to commit health care fraud and fifteen counts of health care fraud. Beginning in 2016, Nathan owned Emerald Lane Therapy Services (Emerald Lane) in Lawton, a massage therapy provider. Delger was a subsequent co-owner of the company. Nathan and Jimmie also owned a separate massage therapy provider, Stars & Stripes Therapy (Stars & Stripes), which opened its doors in Lawton in January 2020. Both businesses purportedly treated TRICARE beneficiaries, submitted claims to the Defense Health Agency (DHA), and received payments from DHA for those services.

According to public record, beginning in January 2018, the defendants conspired together to submit false and fraudulent claims to TRICARE for services that were never rendered. Court documents allege that after TRICARE beneficiaries visited either of the businesses, the defendants would schedule multiple appointments for the beneficiaries many months in advance. If the beneficiary couldn’t make the appointments, or stopped coming altogether, the defendants would nonetheless continue to bill TRICARE as if the beneficiaries had received care. Additionally, Emerald Lane billed TRICARE using the National Provider Identity (NPI) number of an occupational therapist long after the therapist had stopped working for the business. In total, Emerald Lane and Stars & Stripes billed more than $7 million to TRICARE and received nearly $3 million in reimbursement.
