Arizona's healthcare landscape is shaped by its rapidly growing population, diverse geography, and significant retiree community. The Phoenix metropolitan area — one of the fastest-growing metro regions in the country — is home to major health systems including Banner Health, Dignity Health, HonorHealth, and the Mayo Clinic Phoenix campus. Tucson is served by Banner – University Medical Center Tucson and the University of Arizona Health Sciences, a major academic medical center.
Arizona has a large and growing senior population, driving demand for cardiology, orthopedics, oncology, and memory care services. The state also faces significant challenges in serving rural and tribal communities; many counties in eastern and western Arizona are designated as Health Professional Shortage Areas. The Arizona Department of Health Services (ADHS) (azdhs.gov) oversees public health programs, licensing, and health data.
Arizona expanded Medicaid — known in the state as AHCCCS (Arizona Health Care Cost Containment System) — in 2014, covering adults up to 138% of the federal poverty level. AHCCCS is one of the largest Medicaid managed care programs in the country. The state also has a robust private insurance market with multiple carriers offering plans through the ACA marketplace.
The Arizona Medical Board (azmd.gov) licenses and regulates allopathic physicians (MDs), while the Arizona Board of Osteopathic Examiners oversees DOs. Both boards offer online license verification tools.
