INDIANAPOLIS -- The Indiana Medical Licensing Board on Thursday suspended the license of a doctor accused in the overdose deaths of at least nine patients.

Dr. Phillip D. Foley, a general physician from Middletown, and nearly two-dozen supporters gathered at the Indiana Government Center for the hearing Thursday, where the board voted unanimously to suspend his license for 90 days, 6News' Rafael Sanchez reported.

"I wasn't doing anything wrong. I can document everything," Foley told Sanchez after the hearing. He said he also believes the state is going after him because "the state wants to control medicine."

According to the state's petition against Foley, the doctor's handling of 10 patient cases from 1998 to 2009 is questionable.

The state claimed that in many instances, Foley prescribed narcotics without performing a medical examination, as required by law.

In at least nine cases, the state claimed that Foley’s actions contributed to the death of his patients.

The state also accused Foley of writing prescriptions to people even after he was aware that they had been pulled over for driving while under the influence of drugs.

Regulators painted Foley as a man out of control and pointed out a specific date as an example. The state claimed that on April 27, 2007, Foley treated 141 patients and wrote 424 prescriptions.

Based on the state's calculations, Foley would have had to work a nonstop 10-hour day, spending four minutes with each patient, and would have written 1.4 prescriptions per minute.

"The facts laid out today during the hearing clearly indicate that lives were at risk and an emergency suspension of Dr. Foley's medical license was necessary," said Indiana Attorney General Zoeller. "The board's decision to take this important step is meant to protect Hoosiers."

Foley denied the accusations against him and said he will fight to keep his medical license. Foley's supporters, many of them patients, said they are worried about where they will get treatment.

"He's the smartest man I've ever known," said Christopher Bowman, who has been Foley's patient for two years.

Jerry Workman, who said he's been going to Foley's practice for 35 years, said the state's allegations are ludicrous.

"He's a caring doctor, and he doesn't prescribe medicine if you don't need it," Workman said.

Foley said he was planning to retire in July 2010 before the allegations surfaced and said he offered to surrender his license, but the state denied that request.
