A 58-year-old Short Hills man who officials said assumed the identity of another dentist after he lost his own license must pay a $1.1 million fine for submitting false bills to Medicaid.

In addition to the fine, Roben Brookhim has agreed to a 50-year exclusion for participating in any federal health care programs, according to the Office of the Inspector General for the U.S. Department of Health and Human Services.

The settlement resolves Brookhim's civil obligations for the long-time scheme of billing the government under the name of dentist John Kirkland Jr., even after Kirkland died, the Inspector General said.

The government alleged that from 2005 through 2012, Brookhim ran Associated Dental, a dental practice with several locations - even though he was excluded from billing Medicaid for his services.

Brookhim's New Jersey dentist license was temporarily revoked in 1999 over billing concerns, and permanently removed in 2004 when it was discovered he had continued to practice.

At the time, he worked out of offices Springfield, West Orange, New Providence, and West New York. When he was arrested in 2012, he was charged with health care fraud and identity theft. He was convicted of falsifying health care records and spent nine months in prison in 2014.

The 50-year exclusion from participating in government-reimbursed dentistry is one of the longest bans ever imposed, said Gregory Demske, chief counsel for the watchdog arm of the federal department.

"This period of exclusion, coupled with the significant monetary recovery, is an appropriate resolution for an individual who went to such great lengths to defraud a Federal health care program and put patients at risk," Demske said.

Brookhim's 2012 arrest came about after investigators said they received a tip that the dentist was still practicing even though he'd lost his license, according to the New Jersey Division of Consumer Affairs, which oversees licensing of health professionals.
