An Anoka County chiropractor must pay $30,000 and revise the way he does business after investigators found he was improperly enrolling patients in credit card plans and overbilling them, according to an order by the Minnesota Board of Chiropractic Examiners Thursday. Jeffrey M. Styba , who owns Exodus Chiropractic, P.A. in Blaine, took an active part in obtaining health care credit cards for patients, often by providing false income or home ownership information. He admitted he and his staff would just "plug in a number," the order said. Styba billed for services that were not provided, the order said. The board suspended Styba but put that action on hold as long as he takes classes and provides a written plan to correct problems. Read the full order here.
