Medicare prescribing
CMS holds no Part D record for NPI 1831295138 in the most recent year we hold, and that has two readings it does not distinguish between: this provider billed Medicare Part D for nothing that year, or they billed it for ten claims or fewer, which CMS removes from the file before publishing to protect the patients behind them. It does not mean the data is missing, and it does not mean this provider writes no prescriptions — anything paid for privately, by Medicaid, or by a patient is not in this file at all.
