- Registry data comes straight from CMS NPPES, which lists registration, not activity — a listed practice may have moved or closed.
- CMS has no Part D prescriber record for this NPI in the most recent public year. Prescribers who wrote 10 or fewer Part D claims are suppressed, and clinicians who do not prescribe to Medicare enrollees never appear.
