HB 618 Missouri House · 2025 Regular Session

Creates provisions relating to prior authorization of health care services

HB 618 limits health insurers' ability to require prior authorization for medical services starting January 1, 2026. Insurers must approve at least 90% of a provider's past requests for a service before requiring prior authorization, or the provider qualifies for an exemption. Hospitals may qualify for exemptions by entering value-based care agreements with insurers, achieving a 3+ star CMS rating, or having a high prior-authorization approval rate. The bill excludes pharmacy, imaging, cosmetic, and experimental services from exemptions (with annual $100,000 cost limits adjusted for inflation) and requires insurers to provide a 90-day medication coverage grace period if a patient's insurance changes.

MODERATE
HB 618 was amended to modernize prior authorization rules by replacing a rigid six-month evaluation period with a flexible twelve-month period and adding new exemptions for high-performing hospitals and value-based care agreements. The bill also establishes a phased implementation starting January 1, 2026, with annual adjustments to exemption limits based on inflation.
