Mesa Business Owner Sentenced to Over 5 Years for Defrauding AHCCCS and Exploiting American Indian Health Plan

Diana Marie Moore Ordered to Pay Over $21 Million in Restitution and Forfeit Luxury Assets in Medicaid Fraud Scheme

PHOENIX, AZ – Diana Marie Moore, 44, of Mesa, was sentenced to 66 months in prison for defrauding the Arizona Health Care Cost Containment System (AHCCCS) and exploiting the American Indian Health Plan. U.S. District Judge Susan M. Brnovich also ordered Moore to pay $21,730,674.04 in restitution and forfeit multiple luxury assets, including four homes, seven vehicles, designer goods, and artwork, all acquired through her fraudulent activities.

Moore, the owner of Harmony Family Services (HFS) and Harmony Family Services II (HFS II), pleaded guilty to Wire Fraud and Money Laundering in July 2023. She admitted to submitting false applications for her businesses to become AHCCCS providers, concealing her felony conviction, and then engaging in a complex billing scheme that targeted AHCCCS funds earmarked for Native Americans.

From January 2020, Moore exploited a program allowing Native Americans to seek behavioral health treatment without pre-payment review. She obtained AHCCCS identification numbers from enrollees, often paying other providers to transport individuals to her facility for a single day. Afterward, she fraudulently billed AHCCCS for extensive services—sometimes up to 90 days of continuous care—despite no ongoing treatment being provided. In some instances, Moore even billed for services for deceased or imprisoned individuals.


“This type of fraud undermines the vital services provided to underserved Native American populations,” said U.S. Attorney Gary Restaino. “The American Indian Health Plan exists to break barriers to treatment, but Moore manipulated it for personal gain.”

The Internal Revenue Service Criminal Investigation (IRS CI) led the investigation, with support from AHCCCS’s Inspector General’s Office. “This sentencing sends a strong message: those who defraud public programs will face serious consequences,” said Carissa Messick, IRS CI Special Agent in Charge, Phoenix Field Office.

Assistant U.S. Attorney Aron Ketchel, District of Arizona, Phoenix, prosecuted the case.
