Surprise bills and ambulance bills in Arizona

If you got a surprise bill from an out-of-network provider at an in-network facility (emergency care, or non-emergency care where you did not get or did not sign a written disclosure with an estimated cost), and you owe at least $1,000 after insurance and your cost sharing, you can ask the Department for an informal settlement conference and arbitration.

Itemized bills and price estimates in Arizona

Arizona has no general state law giving you a right to an itemized bill within a set time. Use your federal rights to your billing records.

Price estimates

Licensed health care providers must make their direct-pay (cash) prices for at least their 25 most common services available on request or online (not for emergency care). Outpatient surgical centers, labs, imaging centers and urgent care centers must do the same for their most-used services. If you pay the posted direct-pay price in full, the bill is paid in full.
