Healthcare: Banner Health Center in Mesa completes a major expansion
A Banner Health Center in Mesa recently finished an expansion designed to increase appointment capacity for East Valley patients. The project added more than 19,000 square feet, bringing the facility to more than 40,000 square feet, according to a report in Greater Phoenix In Business Magazine.
The expanded center includes 31 additional exam rooms, new medical suites and support space, and a larger on-site lab area for Sonora Quest Laboratories, including extra blood draw stations. The report also noted expanded in-office behavioral health services and the addition of new providers, with more planned this year. The clinic is located at 1917 S. Crismon Road in Mesa.
Health insurance: AHCCCS schedules a behind-the-scenes system upgrade
Arizona’s Medicaid agency, AHCCCS, posted a February 25 modernization update outlining upcoming changes to its Medicaid Enterprise System (MES). A key near-term step is an Electronic Data Interchange (EDI) translator scheduled to go live March 1, 2026.
AHCCCS describes the change as a back-end upgrade intended to improve data exchange with health plans and clearinghouses. For patients, these kinds of upgrades are typically not something to navigate directly, but they can affect how quickly eligibility and claims information moves between organizations, especially during transition periods.
Outbreak watch: CDC posts updated measles totals; county dashboards track respiratory trends

The county also lists an East Valley immunization clinic location in Mesa (1950 S. Country Club Drive) for childhood vaccines by appointment.
