Arizona Health Care Cost Containment System

Arizona Health Care Cost Containment System (AHCCCS), Arizona's state Medicaid agency based in Phoenix, operates as a prime federal grant recipient under the Department of Health and Human Services, administering Medicaid, CHIP, and behavioral health block grants and project grants across the state. AHCCCS is a child entity of the State of Arizona and a U.S. government entity; it does not hold federal contracts and competes in the grant space exclusively as a prime recipient, not a subrecipient (208 of 209 awards in the source are prime grants).

AHCCCS's federal grant portfolio concentrates overwhelmingly on health entitlement and behavioral health services. The Centers for Medicare and Medicaid Services (CMS) dominates both award count and dollar value, anchoring the portfolio with Medicaid entitlement block grants (CFDA 93.778) and CHIP entitlement grants (CFDA 93.767) that together represent the bulk of AHCCCS's annual federal funding. In fiscal year 2026 alone, AHCCCS received $86.927 billion under the Medicaid entitlement grant (CFDA 93.778), $331.218 million under CHIP (CFDA 93.767), and $2.604 billion in supplemental Medicaid funding, distributed quarterly. The Substance Abuse and Mental Health Services Administration (SAMHSA) provides the second major funding stream through a portfolio of behavioral health block grants and project grants. Recent SAMHSA awards include $131.610 million for the Block Grants for Prevention and Treatment of Substance Abuse (CFDA 93.959, performance through September 30, 2027), $54.073 million for Community Mental Health Services block grants (CFDA 93.958, through September 30, 2027), formula grants under Projects for Assistance in Transition from Homelessness (PATH, CFDA 93.150), and project grants addressing opioid response ($15 million+ across Arizona State Opioid Response Grants III and IV), suicide prevention (Arizona 988 State and Territory Improvement), and treatment for pregnant and postpartum women with substance use disorders.

AHCCCS implements these grants through sub-awards to local nonprofit and public service organizations including Catholic Charities Community Services, La Frontera Center, Solari Crisis Services, Arizona Community Health Centers, Mercy Care Plan, and Community Bridges. A December 29, 2025 Cooperative Agreement from CMS totaling $500.966 million under the Rural Health Transformation Program (CFDA 93.798, performance through October 30, 2030) funds innovation in rural healthcare delivery targeting behavioral health, chronic disease, child and maternal health, and workforce development across Arizona via partnerships with the same local organizations. AHCCCS also received a $1.469 million PATH formula grant (July 1, 2025 through June 30, 2027) for homeless services and a $1.459 million PATH award (July 1, 2026 through June 30, 2028).

Activity has remained steady at 8 to 11 awards per year across 2022 through 2025, with one award in 2026 and eight awards with ultimate completion dates in the next twenty-four months facing potential recompete. AHCCCS serves twelve distinct federal customer agencies, but concentration is tight: the top five funders account for 93% of awards, with CMS dominating through entitlement grants and SAMHSA providing behavioral health block grants and project funding. The vendor's role is exclusively administrative and implementer of federal entitlements and formula allocations; it does not develop or sell goods, does not hold IDIQs or GWACs, and does not subcontract federal work to commercial vendors.
