OMIG’s assistance in pursuing this case came into play when DHHS discovered Presman was overbilling Medicare and Medicaid in his private practice. DHHS contacted OMIG requesting Medicaid claim data and verification as to whether the doctor was enrolled as a Medicaid provider. When it was found that Presman was also working full-time at the VA Hospital in Brooklyn, the VA-IG’s Office also became involved with the case.
DHHS and OMIG conducted numerous surveillances, discovering that Presman saw three to four people on a daily basis beyond his primary, full time VA job. An analysis of Medicaid and Medicare billings revealed that Presman was also billing for approximately 20 people a day, each with 45 minute sessions (15 hours a day). When all of these factors were added together it became clear that the billing patterns were impossible. The arrest took place in May 2013.
