Requires that any provider contract between a carrier and a participating health care provider contain specific provisions that prohibit the carrier from revoking, limiting, conditioning, modifying, or restricting a prior authorization if such prior authorization request has been approved and services, drugs, or supplies have been provided or delivered to the patient consistent with such prior authorization unless there is evidence that the request was approved based on fraud or misinformation. The bill also extends from 30 days to 90 days the period of a member’s prescription drug benefit coverage under a new health plan during which a carrier is required to honor a prior authorization by another carrier.
