Senator Janae Shamp of Arizona has raised concerns about inadequate asset checks that she says have allowed many ineligible individuals to remain on Medicaid. She attributes these issues to oversight failures within the Arizona Health Care Cost Containment System (AHCCCS). Shamp made her statement on the social media platform X.
“Why did Arizona check only 23% of Medicaid enrollees for assets,” said Shamp, State Senator for Arizona. “Over a third of Medicaid enrollees were too rich to qualify.”
Recent oversight reports from Arizona’s Auditor General and the Centers for Medicare & Medicaid Services indicate that while Medicaid eligibility screening by AHCCCS has improved, it still permits some individuals with excessive assets to remain enrolled. This highlights a need for stronger verification and coordination with federal databases, as reported by the Arizona Auditor General.
According to a February 2025 AHCCCS eligibility report, approximately 1.1% of Arizona Medicaid enrollees—about 22,500 out of 2 million—were found ineligible due to possessing assets above the legal threshold. This reveals ongoing issues in asset screening procedures, as cited in official state audit findings.
Arizona’s asset verification rate of 1.1% for Medicaid ineligibility is slightly lower than the national average of 1.5% to 2.0%. However, it remains higher than the most rigorous state programs that maintain asset-related errors below 1%, according to a 2023 report by the U.S. Government Accountability Office.
Shamp is the Majority Leader of the Arizona Senate and a Republican representing District 29. She previously worked as a perioperative nurse and currently serves as vice chair of the Senate Health & Human Services Committee, where she supports stricter Medicaid eligibility, according to her official legislative biography.
The AHCCCS was created in 1982 as Arizona’s Medicaid agency; it manages care for over 2.2 million residents and operates under a governor-appointed director. It is recognized as the nation’s first statewide mandatory managed-care Medicaid program, according to its official website.
