A local doctor is among 91 people across America charged recently with defrauding Medicare, according to the Staten Island Advance.

The fraudulent billing supposedly took place back when the doctor worked at Solstice Wellness Center in Brooklyn and Queens, and not now that he practices in Eltingville and Concord.

Court papers say Dr. Billy N. Geris and others in his office would prescribe medical services that weren’t necessary, then pay patients some of what they received from Medicare for the fraudulent claim. Supposedly, the scam took place between January 2009 and April 2010, and pulled in more than $3.4 million from Medicare, prosecutors said.

Eight other people have been charged in this alleged scam, including Dr. Jesse A. Stoff, the former medical director.

Indictments for other, unrelated Medicare fraud schemes also have been raining down hard over the last two weeks nationwide, with 21 people charged beginning on Aug. 24, and indictments for 70 more people being unsealed Tuesday and Wednesday.

Attorney General Eric Holder called these 91 indictments the biggest takedown in Medicare task force history, according to USA Today. Four hundred agencies participated to bring charges in eight different cities, covering $295 million in allegedly false Medicare claims.

Other cases in this sting include billing for services that were never provided, money laundering and, in Miami, threatening to evict Medicare recipients if they did not go along with one of the schemes.
