A doctor who lost his license in 2005 pleaded guilty today to “multiple federal charges stemming from his participation in an insurance fraud scheme and a conspiracy to illegally distribute prescription narcotics,” federal officials said in a statement.

Francisco R. Carbone, 53, of Fairfield, faces up to 65 years in prison on charges of to one count of conspiring to commit mail fraud to defraud insurance carriers, one count of conspiring to commit mail fraud to defraud the State of Connecticut, one count of making a false statement relating to health care matters, and one count of conspiring to distribute controlled substances outside the scope of the usual course of professional practice, the statement said.

Carbone had been licensed to practice medicine and worked in Bridgeport, but in March 2005, the state revoked his license to practice medicine, the statement said.

But between Dec. 2006 and Feb. 2010, Carbone conspired with an attorney and a chiropractor to defraud several insurance companies by exaggerating the auto accident injuries of the attorney’s clients to justify a larger money settlement with insurance companies, the statement said.

“As part of the scheme, the co-conspirators fabricated medical records, prescribed unnecessary pain medication, performed unnecessary chiropractic treatment, ordered and billed for diagnostic tests of questionable medical value, and overstated injuries or permanent partial disabilities that were allegedly caused by the accidents,” the statement said.

Also, from Nov. 2006 through Jan. 2010, James W. Marshall, Jr., a licensed doctor of osteopathic medicine in Monroe, wrote prescriptions for pain medication, including oxycodone and hydrocodone, for Carbone’s patients, the statement said. On March 1, Marshall pleaded guilty to one count of conspiring to distribute controlled substances outside the scope of the usual course of professional practice, “admitting that he wrote more than 145 prescriptions for more than 4,400 pills to numerous patients, without personally meeting, examining, or consulting with the patients who would receive the prescriptions,” the statement said.
