ROCKPORT, Maine — The federal government filed a lawsuit Wednesday claiming a Rockport dentist, who has faced disciplinary action by a state board, filed false claims for government reimbursement.

The civil lawsuit was filed in U.S. District Court in Bangor by the U.S. attorney’s office against Daniel P. Schecter. No criminal charges have been filed.

The lawsuit claims that MaineCare conducted an audit of 50 cases handled by Schecter between Jan. 1, 2009, and Dec. 31, 2011, and that none of the procedures performed were found to have a medical necessity.

The lawsuit states that Schecter submitted false records to get reimbursement he was not owed.

The amount of money owed by the dentist is not specified in the lawsuit, although if he is found to have committed the offenses, he would have to repay the money plus a civil penalty of $5,500 to $11,000 for every false claim.

Schecter twice has been brought before the Maine Board of Dental Examiners. He entered into a consent agreement in 2009 concerning a patient of his who died four days after being treated in January 2007. The dentist agreed to additional education, including in pharmacology, treatment of medically compromised patients and documentation.

Schecter entered into a second consent agreement with the state board after he was found to have been prescribing excessive pain medications. The agreement prohibited him from further prescribing narcotics to treat the pain of patients.

Schecter could not be reached for comment Wednesday afternoon.
