BOSTON (CBS) – Massachusetts Attorney General Maura Healey’s office announced more charges in an amended lawsuit on Thursday against local orthodontist Dr. Mouhab Rizkallah, who was already being accused by Healey of keeping children in braces for longer than medically necessary “to steal millions of dollars”.

The state attorney general’s office said on Thursday that Dr. Rizkallah allegedly charged MassHealth patients for missed or canceled appointments, which is in violation of MassHealth and federal regulations.

Healey’s office alleges that Dr. Rizkallah had MassHealth patients sign a “MassHealth Treatment Contract”, which made patients agree to a minimum $20 for missed or canceled appointments or for appointments rescheduled on less than 24 hours notice.

The new claims were added to a lawsuit accusing the orthodontist of submitting millions in false claims to Mas Health. In addition to keeping children in braces for too long, Dr. Rizkallah is also accused of deceptively billing for mouthguards.

The investigation started with a patient complaint. Healey’s office alleges that Dr. Rizkallah, through two companies, instituted illegal policies and practices since November 2013.

For his MassHealth patients, who were mostly children, Dr. Rizkallah allegedly would often put braces only on their top teeth, even when there was no reason not to also put braces on the bottom teeth. Healey said this “significantly extended” treatment time and increased the amount of money collected from MassHealth.
