Arizona Claims Dispute & Statutory Guide
Arizona operates an At-Fault automobile insurance framework under Title 20 and Title 28 of the Arizona Revised Statutes (A.R.S.). Liability is governed by pure comparative fault under A.R.S. § 12-2505. Medical providers bill optional first-party Medical Payments (MedPay) and enforce statutory healthcare provider liens against third-party liability proceeds under A.R.S. § 33-931, subject to statutory compromise rules.
Statutory Framework & Jurisdiction
At-Fault / Traditional Tort (Pure Comparative Fault & Arizona Healthcare Lien Act)
Arizona is an at-fault tort liability state without mandatory Personal Injury Protection (PIP) insurance. Medical care for motor vehicle collision injuries is funded through optional first-party Medical Payments (MedPay) coverage, private health insurance, or third-party automobile liability insurance. Under Arizona Constitution Art. 18, § 6 and Allstate v. Druke, subrogation of personal injury claims is restricted by public policy, subject to limited statutory MedPay reimbursement under A.R.S. § 20-259.01(J). Healthcare providers secure balances against third-party settlements by recording statutory liens under A.R.S. § 33-931.
PIP / MedPay Coverage & Medical Fee Rules
optional Med Pay Coverage
MedPay is optional in Arizona (commonly written in limits of $1,000 to $10,000+ per person), providing no-fault reimbursement for reasonable medical, surgical, dental, hospital, and ambulance expenses resulting from a motor vehicle collision
limited Subrogation Rule
Under A.R.S. § 20-259.01(J), an auto insurer has a limited statutory right of reimbursement for MedPay benefits paid in excess of $5,000, but only if the claimant recovers from a third party and is fully compensated for all injuries

Healthcare providers routinely obtain patient assignments of MedPay benefits for direct claims submission to automobile insurers

Under A.R.S. § 20-462, insurers must pay clean claims within 30 calendar days of receipt. Claims not paid within 30 days accrue interest at the legal rate from the date the claim became overdue.
health Care Provider Lien Act
Under A.R.S. § 33-931 et seq., hospitals, physicians, and ambulance providers have a statutory lien upon all claims, settlements, and judgments against third-party tortfeasors. To perfect the lien, the provider must record a verified notice of claim of lien in the office of the county recorder within 30 days of patient discharge (or 30 days of service for outpatient providers). Under A.R.S. § 33-934, healthcare liens are subject to statutory compromise if the patient's recovery does not fully compensate them.
