Chicago – Attorney General Kwame Raoul charged a Chicago dentist and dental office employee with defrauding the state out of more than $100,000 in Medicaid funds.

Blanca Murillo, 51, of Brookfield, Illinois, is a licensed dentist who owns Blanco Murillo DDS Inc., a dental office located at 5036 S. Archer Ave. in Chicago’s Archer Heights community. Murillo – along with Jose Luis Carrillo Ibarra, 47, of Berwyn, Illinois – were each charged in Cook County Circuit Court with two counts of theft of government property, each Class X felonies punishable by up to 30 years in prison; two counts of theft, Class 1 felonies punishable by up to 15 years in prison; one count of vendor fraud, a Class 1 felony punishable by up to 15 years in prison; and one count of conspiracy, a Class 1 felony punishable by up to 15 years in prison. Sentences are ultimately determined by the court. Murillo and Carrillo Ibarra were both arraigned on Tuesday, and their next court date is scheduled for July 29.

“Medicaid provides access to lifesaving care to millions of Illinoisans, and it is egregious that a healthcare professional would take advantage of this program for their own financial gain,” Raoul said. “My office’s Medicaid Fraud Control Unit will continue to partner with state and federal agencies to hold individuals who cheat our systems accountable.”

Attorney General Raoul’s office alleges that between January 2018 and November 2024, Murillo – through her dental practices – received payment for over $100,000 in claims for dental services that she did not provide. Raoul’s investigation uncovered that while Carrillo Ibarra was an employee of Murillo’s practice during the time the claims for service were issued, he is not a licensed dentist in the state of Illinois. Murillo is alleged to have known Carrillo Ibarra was not licensed and still paid him to provide dentistry services at her office and billed the state for those services. During the claims for service, Murillo also owned Brite Smile, DDS located at 1504 N. Western Ave. in Chicago’s West Town community.

Raoul’s Medicaid Fraud Control Unit (MFCU) opened an investigation into Murillo and Carrillo Ibarra after receiving a referral from the Illinois Department of Healthcare and Family Services – Office of the Inspector General (HFS-OIG).

“HFS‑OIG is proud to partner with the Attorney General’s Office to protect the integrity of the Illinois Medicaid program,” said HFS Inspector General Brian Dunn. “This action sends a clear message: fraud within Medicaid will not be tolerated, and those who attempt to misuse public funds will be held fully accountable.”

The U.S. Department of Health and Human Services Office of Inspector General (HHS-OIG) assisted in the case.

“Medicaid exists to deliver essential care to the individuals who rely on it, and fraud of this kind ultimately harms patients who trust their providers to act in their best interests,” said Special Agent in Charge Thomas Ethridge of the U.S. Department of Health and Human Services Office of Inspector General (HHS-OIG). “We remain committed to protecting vulnerable individuals and safeguarding the integrity of our health care programs. We will continue working with our law enforcement partners to hold accountable those who put patients at risk.”

The public is reminded that the defendants are presumed innocent until proven guilty in a court of law.

Raoul’s Medicaid Fraud Control Unit receives 75% of its funding from the U.S. Department of Health and Human Services under a grant award totaling $12,584,776 for the federal government’s 2026 fiscal year. The remaining 25%, totaling $4,194,923 for the federal government’s 2026 fiscal year, is funded by the state of Illinois. 

Deputy Bureau Chief Steven Kruger and Assistant Attorney General Dan Duffy are prosecuting the case for Raoul’s MFCU.
