WASHINGTON, Nov. 17, 2016 /PRNewswire/ -- Constantine Cannon LLP is pleased to announce that its qui tam clients Linda Gibb and Donna Geraci aided the U.S. government and the State of New York in recovering more than $10 million over allegations of systemic Medicare and Medicaid fraud by Zwanger-Pesiri Radiology, a large practice with more than 20 locations on New York'sLong Island. The settlement with Zwanger resolves a case initially brought by qui tam relators Ms. Gibb and Ms. Geraci and later joined by the federal government and the State of New York that accused Zwanger of overbilling Medicare and Medicaid. In addition, Zwanger and Dr. Steven Mendelsohn, Zwanger's part-owner, medical director and chief executive officer, pleaded guilty to one criminal charge of healthcare fraud. Ms. Geraci and Ms. Gibb, who were billing specialists at Zwanger, are represented by Constantine Cannon attorneys Timothy McCormack and Molly Knobler and co-counsel Mitchell J. Birzon, a partner at Birzon, Strang & Associates in Smithtown, New York. Soon after joining Zwanger in 2010, Ms. Geraci discovered that the company regularly falsified Medicare and Medicaid claims for services rendered by uncredentialed physicians or at unenrolled practice locations. Senior executives directed her to do whatever was necessary "to get the claims paid." Despite her warnings that this constituted fraud, Zwanger continued to engage in its schemes. Similarly, Zwanger executives ordered its schedulers to "split up" certain tests, i.e. schedule them on different days, no matter how inconvenient and contrary to patients' needs, because Zwanger was paid more when the tests were split. Ms. Gibb complained repeatedly about these and other improper practices, such as automatically performing pelvic and transvaginal ultrasounds — an extremely invasive physical exam — on female patients when their treating physicians had ordered only one of these tests.
