Senate Bill No. [number] aims to revise health utilization review laws in Montana by introducing several key provisions. It mandates that health insurance issuers honor prior authorizations for at least 90 days when enrollees switch health plans, ensuring continuity of care. The bill prohibits prior authorization for prescriptions written at discharge from inpatient care, allowing immediate approval for up to three days, provided the medication cost does not exceed $5,000 per day. Additionally, it establishes that once prior authorization is granted for a covered service, it cannot be rescinded after the service has been provided, with exceptions for fraud or nonpayment.

The bill also requires health insurance issuers to accept and respond to prior authorization requests electronically, streamlining the process for healthcare providers. Notably, it removes the requirement for the use of the SCRIPT standard for electronic prior authorization transactions. The provisions of this act will apply to health care policies issued or renewed after its effective date, and it includes coordination instructions to address potential conflicts with other legislation.
