Criminal Charges for Dentist Who Fraudulently Billed Insurance Companies Nearly $600,000
Defendant Falsely Claimed She Performed 623 Root Canals on 75 Patients

SAN DIEGO, Calif. — A Mira Mesa dentist, April Rose Ambrosio, 58, fraudulently billed multiple insurance companies $592,550 claiming she performed 623 root canals on 75 patients. Ambrosio, who was arraigned in San Diego Superior Court today on 75 counts of insurance fraud, billed eight insurance companies for nearly $600,000 and ultimately received more than $200,000.

Ambrosio's deception involved billing for more than 100 root canals over a three-month period for a family of four.

“This is a case of repeated and flagrant fraud by a medical professional,” District Attorney Summer Stephan said. “Unfortunately, when scam artists bill for dental services not rendered, they get rich at the expense of honest consumers who ultimately pay the price through higher premiums.”

The Department of Insurance spent two years investigating this case and worked closely with the District Attorney’s Insurance Fraud Division to bring Ambrosio to justice. Investigators say she was running the billing scam for three years.

“Medical providers are held to the highest standard and their patients trust them to be honest when it comes to their care,” said Insurance Commissioner Ricardo Lara. “Ambrosio violated that trust when she fraudulently billed for services she never performed.”

If convicted of all charges, Ambrosio faces up to 83 years in prison. She will next be in court on September 5.
