Legislative bill overview

HB 399 revises Montana's prior authorization requirements for healthcare services, modifying the process by which insurers must approve treatments before they are provided. The bill recently passed both chambers and was signed by the Governor on April 16, 2025, becoming law.

Why is this important

Prior authorization is a major point of friction in healthcare delivery—it can delay patient access to necessary treatments, burden providers with administrative work, and create cost barriers. Revising these laws affects how quickly patients receive care, how much administrative overhead providers face, and ultimately healthcare costs and outcomes across Montana.

Potential points of contention

  • Speed vs. Safety: Streamlining prior authorization could accelerate patient access but may reduce insurer oversight of potentially unnecessary or costly procedures
  • Provider burden vs. insurer concerns: Reducing administrative requirements helps providers but may increase insurer liability and healthcare spending
  • Coverage equity: Changes may affect different patient populations differently depending on insurance type and ability to navigate appeal processes
