Dr Syed Imran Ahmed, who billed Medicare for $85 million from 2011 to 2013, was ordered held without bail after prosecutors argued that he might flee to his native Pakistan.
Medicare paid Ahmed more than $7 million for claims during that period.
Assistant U.S. Attorney Turner Buford told the magistrate judge that Ahmed, 49, had wired $2 million to Pakistan just six days after he was questioned by federal agents.
Authorities launched a probe after receiving complaints from two patients disputing that Ahmed had performed the surgical procedures listed on their Medicare documents.
“Ahmed created phantom medical procedures to steal real taxpayer money,” said Brooklyn U.S. Attorney Loretta Lynch.
The feds filed a lien against his posh $4 million home in Muttontown.
The federal complaint alleges that Ahmed billed Medicare for over 480 procedures he allegedly performed on an unidentified patient from June 2011 to October 2011, but the operating log in the hospital listed only four procedures.
Defense lawyer Douglas Nadjari said many of the patients may not realize that the incisions and drainage procedures performed by Ahmed are considered surgeries.
