Chiropractor Ted Stokes pleads not guilty during his arraignment in Androscoggin County Superior Court in Auburn on Thursday.

AUBURN — A Lewiston chiropractor accused of bilking health insurers by continuing to bill them after he’d lost his license to practice said Thursday he isn’t guilty.

Ted Stokes, 52, of Greene appeared in Androscoggin County Superior Court in a jail suit, his ankles shackled. He was indicted by a grand jury Wednesday on a felony count of theft by deception and a misdemeanor count of unlicensed practice. He pleaded not guilty to both counts Thursday.

If convicted on the felony count, he could be sentenced to up to 10 years in prison; on the misdemeanor, up to six months in jail.

He is expected to be released on his own recognizance once he completes a screening with a local agency that keeps tabs on defendants awaiting trial. If he were to fail to appear in court, he would owe the state $5,000.

Authorities said Stokes continued to see patients and billed private and public health insurers for more than a year after the state revoked his license to practice because he fell in arrears on his child support payments by about $10,000.

He was arrested last week and booked at the Androscoggin County Jail.
