Arizona Prior Authorization Laws for Payers & PBMs

Automate Compliance with A.R.S. § 20-2803 Using Banjo Health

Arizona’s prior authorization (PA) regulations, governed under A.R.S. §20-2803, focus heavily on timely care delivery, medical necessity, and limiting administrative friction during emergency and urgent care scenarios.

For payers and PBMs, meeting these expectations across medical and pharmacy PA workflows requires more than manual tracking—it demands intelligent, automated infrastructure.

With Banjo Health, you get a platform designed to help you meet Arizona’s regulatory requirements out of the box, with built-in speed, clinical integrity, and full auditability.

Arizona’s Prior Authorization Requirements

Arizona’s regulations are uniquely structured around emergency and post-emergency care, requiring that:

●    If care is deemed medically necessary after an emergency screening, authorization is automatically granted

●    Plans may not retroactively deny or delay medically necessary follow-up care unless they meet strict documentation and clinical review requirements


This law prioritizes continuity of care and shifts the burden to the payer to justify any denial. Banjo Health automates clinical review checkpoints and decision documentation, so you’re always aligned with the state’s “approve unless exception applies” framework.

Documentation and Medical Necessity

To comply with A.R.S. § 20-2803, health plans must demonstrate that:

●    Denials are based on clear medical necessity standards

●    Documentation is complete and clinically relevant

●    No adverse action is taken if a provider is following standard protocols after an emergency

Banjo Health simplifies this with built-in medical necessity rules and AI-based documentation review—so you never fall short on justification.

Who Reviews PA Requests?

Arizona emphasizes the importance of appropriate clinical review. While the statute doesn’t specify specialty requirements, best practices (and payer liability) demand that peer-level review be:

●    Clinically matched, and

●    Timely, especially post-emergency


Banjo Health ensures peer-to-peer reviews are conducted by the right clinicians—licensed and qualified in the same or similar specialty—automatically routed and tracked.

Appeals, Denials, and Provider Communication

Banjo supports Arizona’s compliance expectations with:

●    Automated denial rationale generation

●    Secure provider messaging portals

●    Real-time appeal tracking


You improve provider trust and reduce friction—all while staying inside regulatory lanes.

Retroactive Denials and Service Interruptions

Arizona prohibits plans from rescinding or denying care that was delivered based on emergency screening outcomes—unless the service was clearly not medically necessary or involved fraud/misrepresentation.

Banjo’s decision engine tracks initial authorization intent, clinical criteria application, and final approvals, making retroactive denials both rare and fully defensible.
