What the payments were

Each payment as the manufacturer categorized it when reporting it to CMS, across 2019–2025. Together they are the general payments above. A category is the reporter’s, and nothing in the record says a payment in any of them was improper.

By program year

CMS reports a program year at a time and also publishes its own total across them, which is what the figures above are. These rows are that total taken apart, not a second set of payments.

The record

National Provider Identifier

Neurological Surgery

Allopathic & Osteopathic Physicians, in CMS's taxonomy.

Licensed in

MD

The state of the license CMS lists first.

Recipient type

Covered Recipient Physician

How CMS classifies the recipient of these payments.

Medicare prescribing

CMS holds no Part D record for NPI 1841236825 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.
