The timeliness of health plan drug coverage policy changes to FDA label revisions.

Introduction: Health plan coverage policies determine specialty drug access and should reflect evolving standards of care; however, the timeliness of policy updates remains unclear. Methods: We used the Tufts Medical Center Specialty Drug Evidence and Coverage (SPEC) Database to evaluate how quickly US commercial health plans updated coverage following Food and Drug Administration (FDA) label changes from 2019 to 2022. We calculated time from label revision to policy update using Kaplan-Meier methods, with new indications for existing drugs as a comparator, and applied Cox proportional hazards models to assess factors associated with update speed. Results: We identified 79 label expansions and 8 contractions across 1279 policies and excluded 421 already aligned with the revised label or using sufficiently broad language. Among 858 remaining decisions, the median time to policy update following label revisions was 29.7 weeks (95% CI: 26.9-33.6), compared to 13.4 weeks for new indications. Coverage updates were faster for label contractions vs expansions (hazard ratio [HR] = 1.30; Conclusion: Despite many policies already aligning with FDA label revisions, coverage updates were often slow and inconsistent. Improving timeliness may improve equitable access to care.
