According to an article published in NewsDay, Federal agents raided the corporate headquarters of Zwanger-Pesiri Radiology in Lindenhurst on Tuesday, March 11, seizing the records of the business that operates 12 medical offices on Long Island, NY. Federal agencies including HHS and the FBI are working with local prosecutors investigating allegations that the company has engaged in a multimillion dollar fraud by overbilling Medicare for services including X-rays, MRI and CT exams, according to the article.

The practice is headed by its husband-wife medical team, according to the website. In addition to Lindenhurst, the company has offices in Elmont, Hicksville, Merrick, Massapequa, Plainview, West Islip, Smithtown, Stony Brook, East Setauket, Patchogue and Medford as advertised on the website. The business was founded in 1958 by Zwanger-Mendelsohn's father, Jerome Zwanger, and another doctor, E.J. Pesiri. Pesiri retired in 2001 and the elder Zwanger in 2008, the site says.
