Because Scottsdale sits entirely within Maricopa County and has no dedicated Superior Court branch or ICA office of its own, every workers' comp claim filed by a Scottsdale employee — whether at a HonorHealth hospital, the Mayo Clinic campus, Discount Tire's headquarters, or one of the 2,900-plus businesses in the Scottsdale Airpark — is processed through the same statewide Industrial Commission of Arizona system. That's different from civil lawsuits, which for Scottsdale residents are typically filed at the Maricopa County Superior Court's downtown Phoenix courthouses, such as the East Court Building at 101 W. Jefferson St.
Once filed, a claim is assigned a claim number and moves through medical evaluation, wage-benefit calculation, and, if disputed, a hearing before an ICA Administrative Law Judge. These hearings aren't held in a local Scottsdale venue — prehearing conferences and many hearings are conducted by video or telephone, since the Commission's hearing-related infrastructure is centralized in Phoenix and Tucson rather than spread across every Arizona city.
If your claim is denied outright, understanding your appeal options before the 90-day window closes is the single most important thing you can do.
