Arizona - AI Claim Denial Restrictions (HB 2175)

This provision establishes that health insurers cannot use artificial intelligence or algorithmic tools as the final decision-maker for prior authorization denials based on medical necessity. Instead, a licensed medical director in Arizona must individually review and approve all such denials. This requirement ensures that a human medical professional, rather than an automated system, makes the ultimate decision on whether a requested medical service is deemed necessary for coverage.

The law aims to prevent fully automated denial processes that could potentially overlook individual patient circumstances or lead to inappropriate coverage decisions. By mandating human oversight, it ensures that critical healthcare access decisions are subject to professional medical judgment and accountability.

The medical director responsible for reviewing and approving prior authorization denials based on medical necessity must hold an active, unrestricted license to practice medicine in Arizona. This specific state licensure requirement is crucial for ensuring that the reviewing physician is accountable to Arizona's medical standards and regulatory bodies.

This provision reinforces local accountability, meaning that medical directors are subject to oversight by the Arizona Medical Board for their professional conduct related to these reviews. It prevents insurers from using medical directors licensed only in other states or jurisdictions for these critical decisions within Arizona.

This provision mandates that all prior authorization denials based on medical necessity must be issued in writing. Crucially, these written denials must include a clear explanation of the reasons for the denial, detailing why the requested treatment or service was not deemed medically necessary. Furthermore, the denial must be personally signed by the Arizona-licensed medical director who conducted the review and made the denial decision.

This ensures transparency and provides patients with a tangible record of the denial and its justification, facilitating their understanding and potential appeal. The personal signature adds a layer of accountability, directly linking the medical director to the decision.

While HB 2175 does not establish new specific penalties, it leverages existing regulatory and professional frameworks for enforcement. Health insurers found to be non-compliant (e.g., issuing denials without proper medical director review) may face enforcement actions from the Arizona Department of Insurance and Financial Institutions, including fines and corrective action orders. Medical directors who fail to fulfill their review obligations or sign denials they did not properly review could face professional disciplinary action from the Arizona Medical Board, potentially including license sanctions.

Patients retain their existing rights to appeal denied claims through internal insurer processes and external review mechanisms. Systematic failure to comply with the law's requirements could also expose insurers to civil liability or bad faith insurance claims from patients harmed by improper denials. The law does not create a new private right of action for violations.

This provision specifies that Arizona HB 2175 will officially take effect on July 1, 2026. This effective date provides health insurers with a transition period of approximately 14 months from the bill's signing date (May 12, 2025) to implement the necessary changes to their operations. During this period, insurers are expected to adapt their claims processing systems, potentially hire additional Arizona-licensed medical directors, and develop new workflows to ensure full compliance with the human review, explanation, and signature requirements for medical necessity denials.

The transition period is designed to allow insurers sufficient time to scale their capacity and adjust their practices without immediate disruption, ensuring a smooth shift to the new regulatory environment.
