SB 449 Montana Senate · 2025 Regular Session

Generally revise health utilization review laws

SB 449 generally revises health utilization review laws, affecting health insurance enrollees, health insurance issuers, and healthcare providers. It requires health insurers to honor existing prior authorizations for at least 90 days when an enrollee changes health plans and prevents requiring repeat step therapy protocols if already completed. The bill prohibits prior authorization for certain prescriptions written at discharge from inpatient care for at least three days. Additionally, it generally prevents health insurers from retroactively denying covered services that received prior authorization and mandates that insurers accept and respond electronically to prior authorization requests from healthcare providers.

MINOR
The bill was shortened by removing the phrase 'AND RESPONDING TO PRIOR AUTHORIZATION REQUESTS' from the summary, likely to streamline the text. Additionally, a specific technical requirement was modified to remove the mandatory use of the 'SCRIPT' standard name, replacing it with a generic reference to the 'standard' for electronic transactions. These changes appear to be editorial refinements rather than substantive policy shifts, as the core obligation for insurers to process electronic prior authorization requests remains intact.
TECHNICAL

Removed the phrase 'AND RESPONDING TO PRIOR AUTHORIZATION REQUESTS' from the bill's summary section.

Changed the requirement to accept electronic prior authorization requests from using the specific 'SCRIPT standard' to using 'the standard' for electronic transactions, simplifying the language without altering the underlying obligation.
