A Springfield chiropractor has pleaded guilty to bilking insurance companies out of more than $48,000. 41-year-old Christopher Leone of Leone Family Chiropractic was charged in federal court for alleged actions between 2005 and 2011. The U. S. Attorney’s office says Leone admitted neither Leone nor any of his employees actually treated the patients as he had documented to the insurance companies and Medicare. The maximum penalty is a year in prison and up to a $100,000fine. Leone has agreed to pay restitution.
