An Atlanta radiologist was sentenced to prison Thursday for health care fraud, wire fraud and mail fraud, the U.S. Attorney's Office announced.

Rajashahker P. Reddy, 41, was sentenced to four years, six months in prison, followed by three years of supervised release. He also was fined $15,000 and ordered to pay restitution of more than $900,000.

“This physician fraudulently cut corners at the expense of the hospitals he worked for and the patients who were being treated," U.S. Attorney Sally Quillian Yates said in the news release.

Reddy was convicted in July. He was found guilty of signing thousands of reports that were supposed to include his medical findings, but the work was actually performed by non-qualified medical assistants, authorities said. The evidence revealed that from May 2007 through January 2008, Reddy sent the reports -- mainly involving X-rays, but also including CT scans, mammograms and ultrasounds --  to several hospitals.

His company, Reddy Solutions Inc., provided radiologist coverage to hospitals in the Southeast that otherwise would not have full-time coverage, authorities said.

Reddy also was convicted of obstructing the investigation by instructing employees to destroy records and create new ones that indicated he had done the work instead of the assistants.
