Medicare Part D only. Counts and ordering reflect Medicare Part D claims (2024) from CMS — they exclude cash-pay, commercial, and Medicaid prescriptions and undercount cash-pay categories (e.g. GLP-1 weight-loss, testosterone). Not a quality or "best" ranking. Absence does not mean a provider does not prescribe topiramate. Source: CMS NPPES (June 2026).
