Bill Summary · SB 1066

Legislative bill overview

SB 1066 would restrict insurance companies' use of artificial intelligence systems to deny prior authorization requests for medical treatments or to determine whether treatments are experimental. The bill appears designed to prevent AI algorithms from making autonomous decisions that block patient access to potentially necessary medical care without human review.

Why is this important

Prior authorization denials can delay or prevent patients from accessing prescribed treatments, potentially worsening health outcomes. As insurers increasingly deploy AI to manage these decisions at scale, this bill addresses concerns that automated systems may make flawed medical judgments or lack the contextual understanding needed for complex cases. The stakes are significant for both patient access and insurer cost management.

Potential points of contention

  • Medical vs. cost control: Insurance companies argue AI systems help control unnecessary spending; patient advocates worry this restricts legitimate treatment access and shifts decision-making power away from doctors and patients.
  • AI capability assumptions: The bill assumes AI cannot reliably make these determinations, but insurers may contend their systems are evidence-based and more consistent than human reviewers.
  • Implementation clarity: The bill's language about what constitutes an "AI denial" versus human denial using AI-generated recommendations remains potentially ambiguous and could create litigation over compliance.
