A lawsuit filed by Geico, the second-largest auto insurer in the U.S., alleges that the owner of a Brooklyn medical supply company defrauded Geico and other insurers by billing them for unnecessary medical equipment, including orthotic devices and pain-relief accessories.

According to the complaint, which was filed in the Eastern District of New York and surfaced by Law.com Radar, Alexander Gorbachev and his business Grand Medical Supply provided equipment in response to prescriptions from doctors who treated the victims of no-fault automobile crashes. The doctors are not named as defendants in the suit.
