PORTLAND — A Kittery business and its president each pleaded guilty today in U.S. District Court to committing health care fraud

Peter Enzinger and Seacoast Sleep Solutions were accused of a scheme to defraud insurance carriers of about $220,000. They’re accused of billing carriers for products that weren’t delivered, were more expensive than those actually delivered and for equipment patients had returned.

Enzinger faces up to 10 years in prison and a fine of up to $250,000. The company faces a maximum fine of $500,000. They must pay restitution to the carriers.

The company has also agreed to forfeit $50,000, according to Toby Dilworth, the defendants’ attorney. He said that the company was sold earlier this year.

In July, Enzinger was convicted of making false statements on a Small Business Administration loan application. He is awaiting sentencing on that charge.
