Fifteen chiropractors, including Robin Stacy Long of Newhall, have been charged in a $6 million insurance fraud and illegal kickback scheme involving automobile collision medical claims, the Los Angeles County District Attorney’s Office announced Friday.

The felony complaint in case BA477147 lists a total of 18 felony counts, including charges against all of the defendants of insurance fraud and participating in patient referral rebates when licensed in the healing arts or as a chiropractor.

Most of the defendants were arrested in a sweep yesterday and are expected to be arraigned on May 6 in Department 30 of the Foltz Criminal Justice Center. The case was filed on April 26.

The alleged ringleader of the operation, Yury Chernega (dob 7/1/71) of Studio City, faces four counts each of the aforementioned charges as well as four counts of failure to file income tax return and one count of money laundering. The charges include allegations of taking more than $500,000 from about 30 insurance companies through fraud and embezzlement.

He faces a possible maximum sentence of 18 years and nine months in state prison if convicted as charged. Prosecutors are requesting that his bail be set at $325,000.

From 2015 through 2018, Chernega allegedly offered to refer new patients to other chiropractors in return for an illegal referral fee, through which he collected about $6 million, prosecutors said. The patients allegedly had been involved in automobile collisions.

The defendants also are accused of filing false claims for medical services they never provided. Additionally, Chernega allegedly didn’t report the income from the illegal kickbacks on his taxes, prosecutors said.

Deputy District Attorneys Heba Matta and LaChandra Wilkerson of the Auto Insurance Fraud Division are prosecuting the case.

The case remains under investigation by the District Attorney’s Office, Bureau of Investigation, with assistance from the California Department of Insurance, the California Franchise Tax Board, the California Board of Chiropractic Examiners and the National Insurance Crime Bureau.
