Medicare prescribing
CMS holds no Part D record for NPI 1669490488 in the most recent year we hold. A prescriber is in that file when they billed Medicare Part D that year, so an absence here means no Part D billing on record — not that the data is missing, and not that this provider writes no prescriptions. Prescriptions paid for privately, by Medicaid, or by a patient are not in this file at all.
