FULTONDALE, Ala. (AP) — An Alabama doctor has pleaded guilty to prescribing drugs to patients without a medical reason, officials said.

Dr. Paul Roberts, 48, pleaded guilty Monday to 12 counts of prescribing controlled substances without a legitimate medical purpose, two counts of health care fraud and two counts of health care scheming, news outlets reported.

Roberts was the former co-owner of Southeast Urgent Care in Fultondale.

A Department of Justice press release said Roberts allowed unqualified staff members, including an X-ray technician, to prescribe controlled substances to patients using prescriptions presigned by Roberts. The release said Roberts also illegally gave two women oxycodone prescriptions. He issued them to one in exchange for sexual favors and to the other even though he knew that she was abusing controlled substances.

Roberts fraudulently billed health care providers for services he didn’t render and for compound medications patients never received, the release said.

As part of the plea agreement, Roberts stipulated to a 72-month sentence and agreed to surrender his Alabama and other State medical licenses. He also agreed to pay a fine of $100,000 and restitution of $2.2 million.
