An Armenian hard case got 10 years’ hard time Thursday.

Robert Terdjanian was sentenced in Manhattan Federal Court for his role in multiple schemes, including Medicare fraud that scammed taxpayers out of $35 million.

The 40-year-old crook pleaded guilty in 2011 to racketeering conspiracy after prosecutors said he led the New York arm of an Armenian mob operation that stole the identities of patients and doctors.

Prosecutors said Terdjanian, whose rap sheet includes burglary and weapons convictions, threatened to disembowel an associate in 2009 at a Brighton Beach restaurant.

“I just wish to apologize to my family, especially my wife,” he said Thursday.
