Overview of the Legislation
On October 13, 2023, California Governor Gavin Newsom signed into law Senate Bill 41, aimed at regulating pharmacy benefit managers (PBMs) in the state. This legislation mandates that all PBMs be licensed by the California Department of Insurance and prohibits practices such as spread pricing and steering patients toward affiliated pharmacies. The law also requires PBMs to pass all rebates directly to payers or patients and restricts them from entering exclusivity agreements with drug manufacturers. Newsom's office highlighted the concentration of the PBM market, dominated by CVS Caremark, Express Scripts, and Optum Rx, which are integrated with major insurers Aetna, Cigna, and UnitedHealthcare.
Legislative Context and Goals
State Senator Scott Wiener, who introduced the bill, emphasized that SB 41 represents California's commitment to consumer protection against large corporations that may exploit patients regarding essential medications. The legislation builds on earlier reforms aimed at increasing transparency and accountability in the PBM industry, which has faced criticism for contributing to rising drug costs.
Industry Response and Criticism
The Pharmaceutical Care Management Association (PCMA), a leading lobbying group for the PBM industry, criticized the legislation, claiming it would not achieve its intended goals of reducing drug costs. They argued that the new regulations would ultimately lead to higher prices for consumers, stating, “This is Big Pharma politics and Californian patients, consumers, employers, unions and plan sponsors will be the ones who pay the higher prices delivered by this misguided legislation."
Broader Implications
California's move to regulate PBMs aligns with similar actions taken by other states, with 15 states having already banned spread pricing practices. The legislation comes amid ongoing discussions at the federal level regarding PBM reform, as Congress has yet to enact comprehensive changes to address the rising costs of prescription drugs.
