- Registry data comes straight from CMS NPPES, which lists registration, not activity — a listed practice may have moved or closed.
- Part D covers Medicare prescription drug enrollees only. Commercial, Medicaid and cash-pay prescribing is not included, so these figures are a floor on real volume, not the whole picture.
- CMS publishes the Part D file annually, roughly two years behind the prescribing year. Drugs with 10 or fewer claims are suppressed.
