The United States filed a complaint under the False Claims Act against Yury Gampel, a chiropractor, 15 Modern Vascular office-based labs located throughout the United States primarily owned by Gampel, and five Modern Vascular-affiliated companies owned by Gampel, for engaging in allegedly illegal financial relationships and transactions. Office-based labs, such as the ones named as defendants here, are an extension of a physician’s office where physicians conduct examinations and procedures on an ambulatory basis. The United States’ complaint alleges that from at least Jan. 1, 2018, through June 30, 2022, Gampel and the Modern Vascular defendants offered physicians the opportunity to invest in Modern Vascular office-based labs to induce them to refer their Medicare and TRICARE patients to Modern Vascular for the treatment of peripheral arterial disease. The complaint also alleges that Gampel pressured vascular surgeons and interventional radiologists employed at the Modern Vascular office-based labs to increase the number of invasive surgical procedures performed by tracking procedures and setting aggressive weekly and monthly goals for such procedures.
