Once you report a work injury to your employer, Arizona law puts the obligation on the employer to notify their workers' comp insurance carrier, which then reports the claim to the Industrial Commission of Arizona. Coverage itself is required under A.R.S. § 23-961 for the large majority of Arizona employers, so whether you work in ASU's Ira A. Fulton Schools of Engineering facilities, a State Farm claims-support role at Marina Heights, GoDaddy's Tempe headquarters, or a warehouse position at Amazon's DPX4 fulfillment center, your employer should already have coverage in place before you're ever injured.
Because the ICA's only physical hearing offices are in Phoenix and Tucson, Tempe claimants shouldn't expect a local courthouse process. Prehearing conferences are commonly handled by phone or Google Meet, and Administrative Law Judge hearings are often conducted by video conference rather than in person. This is different from Maricopa County's Superior Court system — which handles civil, criminal, and family matters for Tempe residents out of the Central Court Building in downtown Phoenix — because a workers' comp claim itself never goes to Superior Court; only a separate third-party lawsuit arising from the same accident would.
If your claim gets denied at any stage, it helps to understand the appeal process for a denied Arizona workers' comp claim before your 90-day window to request a hearing runs out.
