A 60-year-old Richmond man, Paul Njoku, is now in custody on charges of making false statements in his scheme to defraud Medicare. The five-count indictment, returned Feb. 3, alleges Njoku made false statements relating to health care matters by copying and pasting doctor and nurse signatures onto patient paperwork. According to the charges, Njoku owned and operated Opnet Healthcare Services Inc. doing business as P&P Healthcare Services. Medicare had made several requests to them seeking supporting documentation for billed claims. In response, Njoku allegedly falsified patient treatment notes and home health certification paperwork by copying and pasting the signatures of a doctor and a nurse.
