SpineFrontier Kickback Scheme Unveiled, Multiple Sentenced

A Missouri surgeon and a Kansas medical device distributor have been sentenced for their roles in a kickback scheme involving SpineFrontier, Inc. , a company that sold spinal implants. Jason Montone, DO, 50, of Lawson, Missouri, and John Balzer, 48, of Lenexa, Kansas, were both sentenced to one year of supervised release.

Montone was ordered to forfeit $379,000, while Balzer was ordered to forfeit $947,500, the U. S. Attorney's Office said.

Montone pleaded guilty in October 2020 to conspiracy to violate the Anti-Kickback statute and obstruction. Balzer pleaded guilty in September 2020 to conspiracy to violate the Anti-Kickback statute and witness tampering. Both cooperated with the government's investigation, according to the Justice Department.

Kickback Scheme Details

The scheme, which ran from late 2012 to October 2015, involved SpineFrontier paying Montone through a sham consulting program. Montone was allegedly paid $500 to $750 per hour for consulting services that were minimally performed. The payments were purportedly for gathering technical feedback about SpineFrontier's products, but prosecutors allege they were actually used to induce Montone to use the company's products in surgeries.

SpineFrontier tracked Montone's sales volume to determine payment amounts, irrespective of the consulting work actually done. Montone was promised 10% of the revenue from surgeries he performed using SpineFrontier products, while Balzer received a 25% commission on revenue generated by Montone's use of the products. Over the course of the conspiracy, Balzer received over $1.2 million in commissions.

Sentences for SpineFrontier Executives

SpineFrontier's CEO, Kingsley Chin, pleaded guilty in May 2025 to making false statements to the Centers for Medicare & Medicaid Services. He was sentenced in August 2025 to one year of supervised release, with the first six months in home confinement. Chin was also fined $9,500 and agreed to a $40,000 civil settlement. His company agreed to pay $855,000 in a related civil settlement.

Aditya Humad, the CFO of SpineFrontier, pleaded guilty in May 2026 to conspiracy to violate the Anti-Kickback statute. He was sentenced in August 2026 to four months in prison followed by one year of supervised release. Humad was fined $9,500 and agreed to a $150,000 civil settlement.

Civil Settlements with Doctors

In March 2020, five doctors agreed to civil settlements to resolve allegations of accepting sham consulting fees from SpineFrontier. The settlements ranged from $105,149 to $486,985. In April 2020, Dr.

John Carlson agreed to pay $1. 75 million to resolve similar allegations.

The case was prosecuted by Assistant U. S. Attorneys Abraham R.

George, Christopher R. Looney, and Mackenzie A. Queenin, with the announcement made by U.

S. Attorney Leah B. Foley and other federal officials.
