Iowa Bans AI in Health Insurance Prior Authorizations

The legislation, signed by Governor Reynolds, targets the prior‑authorization process that requires doctors to obtain insurer approval before a procedure or medication is provided. Critics have argued that algorithmic decisions lack transparency and can delay care.

Key provisions of House File 2635 include a blanket prohibition on any artificial‑intelligence system used to deny a prior‑authorization request. The rule applies to all commercial and public health plans operating in the state. In addition, the law removes the prior‑authorization requirement for any cancer screening that clinical guidelines label as recommended, such as mammograms and colonoscopies. Finally, insurers may no longer penalize physicians who refer patients to providers outside the network, preserving clinical discretion.

The practical impact is immediate. Physicians can submit prior‑authorization paperwork without fearing an AI‑generated denial, and patients seeking routine cancer screening will encounter fewer administrative hurdles. Insurers must adjust their workflow systems to replace any AI‑based triage tools with human review, potentially increasing processing time but improving accountability.

Evidence on AI’s role in prior authorizations remains limited. A 2022 cohort study of 12,000 claims found that algorithmic denials correlated with longer wait times, but the design could not prove causation. No randomized controlled trial has evaluated outcomes after removing AI from the process, so the law’s effectiveness will be measured by future data on claim turnaround and patient access.

What to watch next: state regulators will monitor claim‑processing metrics for the next 12 months, and other states may consider similar bans if Iowa’s model shows reduced delays without cost spikes.
