Bill protection rules

Arizona has no dedicated patient-billing statute in our registry, so the federal baseline applies: non-profit hospitals must offer financial assistance under IRS §501(r) (26 U.S.C. §501(r)), and the federal No Surprises Act limits most surprise out-of-network bills. Ask the hospital for its written financial assistance policy — they are required to have one.
