What this law does
Drafted with AI from the cited sources under the direction of UnGovr staff. UnGovr holds editorial responsibility for this page.
This measure passed both chambers of the Nevada Legislature but was vetoed by the Governor and did not become law; what follows is what it would have required.
A health or dental insurer, and a governing body of a Nevada county, school district, or other local government that provides health insurance through a plan of self-insurance, would have been barred from solely relying on an artificial intelligence system or automated decision tool to deny, modify, or reduce the scope of a prior-authorization request, or to terminate or reduce previously approved coverage; the insurer would have had to approve a request unless a licensed health care professional with relevant expertise determined the requested care was not medically necessary or was experimental.
Nevada's currently codified prior-authorization statute, NRS 687B.970, contains no such artificial-intelligence restriction, confirming this measure never took effect.
