Arizona Medicaid covered approximately 1.62-2.18M people. Two independent sources give different-period figures for total Arizona Medicaid/CHIP enrollment: KFF's state indicator (1,621,802, May 2026) and CMS's 2024 Medicaid Managed Care Enrollment and Program Characteristics report (2,181,548 total Medicaid enrollees, July 1, 2024). Consistent with continued post-pandemic 'unwinding' enrollment decline between mid-2024 and mid-2026, not a data error. Reported as a range rather than a single false-precision number.
Funding & federal match
Arizona has adopted ACA Medicaid expansion, effective 2014-01-01.
For FFY2026 (Oct 1, 2025 - Sep 30, 2026), Arizona's Federal Medical Assistance Percentage (FMAP) is 64.34%.
Delivery system & managed care
A large share of Arizona Medicaid is delivered through managed care organizations (MCOs) rather than fee-for-service — estimates range from 78.7-80.4% of Medicaid enrollees.
Waivers
Arizona operates Medicaid managed care under the Arizona Health Care Cost Containment System (AHCCCS) Section 1115 Demonstration, a Section 1115 demonstration waiver. Umbrella demonstration authorizing Arizona's long-standing statewide mandatory managed care Medicaid program (AHCCCS), including integrated acute, behavioral health, and long-term care managed care for most eligibility groups. Renewed for a five-year period, October 1, 2022 through September 30, 2027. Amendments under this demonstration include AHCCCS CARE (targeted benefits for enrollees between 100-138% FPL) and AHCCCS Works (a paused community-engagement/work-requirement component).
