BRIGHAM CITY -- A Brigham City doctor has pleaded not guilty to federal charges that he wrote illegal prescriptions for painkillers.
Investigators say Dr. Dewey MacKay wrote some 37,000 prescriptions for painkillers in just four years -- a pace higher than other doctors in the state.
A federal indictment announced last month accuses MacKay of prescribing pills without conducting medical exams. It also says new patients received limited or no physical exam to diagnose the cause of the patient's reported pain.
Tuesday MacKay pleaded not guilty to the indictment. His case is now expected to go to trial in June 2011.
The court has prohibited MacKay from writing prescriptions for controlled substances until his trial concludes.
