Mesa health brief: Medicaid formulary update, county air-quality tracking, and measles monitoring

ByWeence

Mesa, AZ – March 4, 2026 – Medicaid formulary changes, updated county air-quality tracking, and measles monitoring resources for Mesa residents.

Health insurance: Medicaid formulary update posted for April 1

Arizona Complete Health-Complete Care Plan posted a Medicaid formulary update dated Feb. 26, outlining changes scheduled to take effect April 1, 2026. The insurer said the updates reflect AHCCCS formulary changes based on recommendations from the January 13, 2026, AHCCCS Pharmacy & Therapeutics Committee.

The notice directs clinicians and pharmacies to review the plan’s Preferred Drug Lists and highlights that some medications may shift between preferred and non-preferred status. While the update is aimed primarily at prescribers and dispensing sites, members can also be affected if a medication’s coverage status changes after April 1.

For patients, the practical impact is often administrative: a refill that was previously covered one way may later require a different process. Plan communications and pharmacy check-ins are commonly used to help avoid surprises around coverage changes and timing.

Public health: Air-quality conditions tracked daily across Maricopa County

The Maricopa County Air Quality Department’s public status map was updated March 3 and provides an Air Quality Index (AQI) overview and category definitions ranging from Good to Hazardous. The map is one of the county’s primary public tools for tracking day-to-day conditions across monitoring sites in the metro area, including the East Valley.

The AQI categories can help residents understand when air quality is broadly acceptable and when sensitive groups may need to take extra caution, based on the county’s published definitions.

Outbreak watch: Measles activity remains elevated nationally

A Feb. 27 national report citing the Centers for Disease Control and Prevention said the U.S. measles count reached 1,136 confirmed cases as of Feb. 26, 2026, surpassing 1,000 cases in the first two months of the year. Arizona is among the jurisdictions that have reported cases in 2026, according to CDC tallies referenced in the report.

In Maricopa County, public health officials continue to post measles information and exposure updates online. Separately, Maricopa County Public Health continues weekly respiratory-virus dashboards during the 2025–2026 season for COVID-19, influenza, and RSV.

For residents looking for vaccination services, Maricopa County lists an East Valley immunization clinic in Mesa at 1950 S. Country Club Drive, with appointments scheduled by phone.
