Arizona’s Medicaid agency, the Arizona Health Care Cost Containment System (AHCCCS), developed the Health Opportunities (H2O) waiver to cover health-related social need interventions as Medicaid services for eligible populations. The H20 waiver complements the agency’s housing program, which provides rent subsidies to nearly 3,000 individuals with serious mental illness who also experience homelessness. By participating in the Accelerator, Arizona seeks to educate those who are experiencing homelessness and those at risk of becoming homeless about housing services and interventions. Arizona will also support housing and services providers to identify opportunities to use variety of funding sources to provide additional housing and supportive services to eligible populations. Arizona also seeks to maximize housing stability for Medicaid members by providing wraparound services using the H2O waiver, the Arizona Long Term Care System (ALTCS), and  home and community-based services provided through the state’s Older Americans Act programs.

The team is led by Arizona’s Medicaid office and includes representatives from the state’s continuums of care, the state's housing finance agency, local public housing authorities, area agencies on aging, health entities, and housing and homelessness programs.
