NASHVILLE, Tenn. (AP) — The United States government and the state of Tennessee have sued a Lenoir City chiropractor and a Manchester doctor, accusing them both of fraud and operating pill mills.

Officials with the U.S. Attorney's office in Nashville say the men are accused of defrauding Medicare and TennCare of over $1 million.

The suit names Matthew Anderson, a Lenoir City chiropractor, and David Florence, a doctor of osteopathy, from Manchester. Current telephone listings for both men were not publicly available.     

Officials say Anderson operated four pain clinics, and at least one was a pill mill. Court documents say he reaped over $5 million from the clinics. They also say Dr. Florence was running an illegal prescription drug racket out of the Center for Advanced Medicine in Manchester.
