Relating to: use of artificial intelligence to deny prior authorization for medical necessity or experimental status.
SB 1066 prohibits health insurance companies (including disability insurance and self-insured plans) from using artificial intelligence to deny prior authorization for medical treatments or experimental procedures. Instead, the bill requires a licensed healthcare provider to review these requests before a denial can be issued. It directly affects insurers that currently use AI for these decisions and healthcare providers who seek approval for patient care. The law takes effect in the fourth month after publication, with specific transition rules for plans under collective bargaining agreements.
