Arizona launches AI tool to review Medicaid claims before payment
Arizona will deploy an artificial intelligence system to screen healthcare provider claims for fraud before money leaves the state's coffers, Gov. Katie Hobbs announced in a May 7 letter to federal health officials.
The state's Medicaid agency, the Arizona Health Care Cost Containment System (AHCCCS), will use the tool to rank claims by fraud risk. Human reviewers will examine the highest-risk submissions, while compliant providers receive faster payment approval.
Hobbs said the system is the nation's first "AI-informed Medicaid prepayment review system." The announcement came in response to a directive from Centers for Medicare and Medicaid Services Administrator Dr. Mehmet Oz, who ordered all 50 states to revalidate high-risk providers in their Medicaid programs.
How the system works
Alivia Analytics, an East Coast company specializing in healthcare data analysis, built the tool. According to Alivia's website, Missouri's Medicaid program used the company's fraud detection system to recover improperly used funds through retrospective audits.
The AI ranks claims before payment, allowing human review of flagged cases while faster processing continues for providers with clean compliance records. This approach costs less than recovering improper payments after they've been made, Hobbs wrote.
"This reflects Arizona's commitment to catching problems before money goes out the door, rather than relying on post-payment recovery, which is costlier, less effective, and yields only a fraction of improper payments," she wrote to Oz.
Background: Delays and fraud investigations
Prepayment review delays at AHCCCS became a contentious issue in the Arizona Legislature. The state's Medicaid agency tightened controls after uncovering a fraud scheme involving sober living homes that exploited Native American members to collect payments from the American Indian Health Plan.
The crackdown created months-long delays for legitimate providers. Some clinics closed or stopped treating patients while awaiting approval. State Senator Carine Werner's Health and Human Services Committee held oversight hearings on the agency's response.
Republicans in the Legislature have pushed multiple Medicaid reforms this session, some of which Hobbs vetoed. Lawmakers sought to require more frequent eligibility checks to prevent fraud. The governor characterized these proposals as "unfunded mandates" in veto letters.
Political context
Hobbs faces criticism from Republicans ahead of November's gubernatorial election. Congressman Andy Biggs, the frontrunner in the GOP primary, cited estimates claiming the state lost $10 billion to Medicaid fraud, though the sober living home scheme cost around $2.5 billion.
The governor also flagged the strain on AHCCCS from federal funding cuts and changes to Medicaid eligibility requirements. In her letter to Oz, Hobbs asked CMS to recognize "the real costs of these mandates" and support Arizona in securing appropriate federal resources.
AHCCCS will submit a revalidation strategy for high-risk providers to CMS in the coming weeks. The agency has not yet clarified which provider types CMS considers high-risk.
