Federal prosecutors in Miami said Friday that 57-year-old Dr. Selwyn Carrington is charged with conspiracy to distribute controlled substances, which carries a 20-year maximum prison sentence.
Court document charge that oxycodone, Percocet and other pills prone to abuse were distributed using prescriptions that Carrington would sign in advance without seeing any patients.
The clinics allegedly paid him $5,000 a month to sign blank prescriptions.
Most of the prescriptions were paid by the Florida Medicaid program.
A message seeking comment left on Carrington's office voice mail was not returned.
Court records did not list an attorney for him.
Federal and state authorities have been cracking down on Florida pill mills.
