Missouri enacts pharmacy benefits manager disclosure and reimbursement laws

Missouri's House Bill 840, introduced on March 11, 2025, aims to enhance transparency and accountability within the pharmacy benefits management (PBM) sector. The bill seeks to address growing concerns over the practices of PBMs, which have been criticized for their role in escalating prescription drug costs and creating conflicts of interest.

Key provisions of House Bill 840 include the establishment of a fiduciary duty for PBMs towards health benefit plan sponsors and their covered individuals. This means that PBMs must act in the best interests of these entities, disclosing any actions that could lead to increased costs or conflicts of interest. Additionally, the bill prohibits PBMs from charging health plans more for prescription drugs than what they reimburse pharmacies, aiming to eliminate profit margins that could inflate drug prices.

The legislation also empowers health benefit plan sponsors and pharmacies to discuss claims data and costs openly, fostering a more collaborative environment that could lead to better pricing strategies for consumers. The Department of Commerce and Insurance will be tasked with enforcing these regulations, ensuring compliance among PBMs operating in Missouri.

Debate surrounding House Bill 840 has been robust, with supporters arguing that it will lead to lower drug prices and greater accountability in the healthcare system. Critics, however, express concerns that the bill may impose excessive regulations on PBMs, potentially disrupting the existing healthcare framework and affecting the availability of certain medications.

The implications of this bill are significant. If passed, it could reshape the landscape of pharmacy benefits management in Missouri, potentially leading to lower prescription costs for consumers and increased transparency in drug pricing. Experts suggest that similar legislation could be adopted in other states, setting a precedent for nationwide reforms in the PBM industry.

As the bill progresses through the legislative process, stakeholders from various sectors, including healthcare providers, insurers, and patient advocacy groups, are closely monitoring its developments. The outcome of House Bill 840 could have lasting effects on how prescription drugs are managed and priced, ultimately impacting the affordability of healthcare for Missouri residents.
