PHOENIX, Arizona — Federal prosecutors have accused Las Vegas sales executive Brian Rowan of helping operate an extensive wound-allograft scheme that allegedly targeted Medicare, TRICARE, CHAMPVA, and commercial insurers through medically unnecessary treatments and concealed financial incentives. Rowan allegedly earned more than $24 million from the operation before purchasing multimillion-dollar residences, substantial life-insurance policies, luxury vehicles, expensive watches, and other property that prosecutors may seek to connect with criminally derived proceeds. Prosecutors allege that Rowan caused hundreds of millions of dollars in illegal kickbacks, bribes, rebates, commissions, and purchasing incentives to reach sales representatives and medical providers throughout the country during the suspected operation. Prosecutors claim providers received invoices showing amounts exceeding their genuine acquisition costs and then used those represented amounts when seeking Medicare reimbursement, allegedly inflating payments while concealing undisclosed profits returned through separate arrangements.
