High prescription drug costs are a substantial problem for many patients who cannot afford their medications, even with health insurance. Capping monthly out-of-pocket (OOP) costs for high-cost drugs may increase the affordability of these medications. In January 2016, Covered California implemented a monthly cap on OOP costs for high-cost drugs to increase patient access. We evaluated the association of this cap with high-cost drug use and OOP spending.
