Navigating Valley of the Sun & Tucson Hospital Networks in 2027
Across Maricopa, Pinal, and Pima counties, hospital and specialist access is divided among five major systems: Banner Health (including Banner – University Medical Center Phoenix, Banner – University Medical Center Tucson & South, Banner Desert & Cardon Children's in Mesa, Banner Thunderbird in Glendale, Banner Estrella, Banner Boswell & Del E. Webb in Sun City, and Banner MD Anderson Cancer Center in Gilbert), HonorHealth (Scottsdale Osborn, Scottsdale Shea, Scottsdale Thompson Peak, Deer Valley, John C. Lincoln, Sonoran Crossing, and Four Peaks), Dignity Health Arizona (St. Joseph's Hospital and Medical Center / Barrow Neurological Institute, Chandler Regional, and Mercy Gilbert), Mayo Clinic Arizona (Phoenix Hospital & Scottsdale Clinic), and TMC Health (Tucson Medical Center).
On the Arizona ACA Marketplace, insurers frequently offer system-branded or narrow HMO tiers that include Banner Health while excluding HonorHealth (or vice versa), making pre-enrollment verification essential.

3 Steps for Maricopa, Pinal & Pima County Residents
- Check the Sub-Network Name on BCBS of Arizona, Oscar & Ambetter Plans: In Maricopa County, a single carrier often sells multiple plans side by side — one built around Banner Health and another built around HonorHealth or Dignity Health.
- Verify Sun City, Surprise & East Valley Oncology Access: If you use Banner MD Anderson Cancer Center in Gilbert, Barrow Neurological Institute at Dignity Health St. Joseph's, or Mayo Clinic Arizona, confirm tertiary specialty coverage before December 15.
- Compare Pima County (Tucson) Networks Separately: Tucson plans use Pima County rating area networks centered on Banner – University Medical Center Tucson, Tucson Medical Center (TMC), and Carondelet St. Mary's / St. Joseph's.
