Payments from drug & device makers
What this record shows
This record is dominated by consulting fees: $49,671 of the $55,164 with a category attached, or 90.0%. Boehringer Ingelheim accounts for 61.1% of it on its own, with 3 other manufacturers making up the rest. Reporting peaked in 2023 at $24,924 and has fallen 54.5% since, to $11,350 in 2025. Among nephrology clinicians in MD with any reported payments, this total sits in the top 5% — high for the specialty, which is a reason to read the composition above rather than the number alone.

General payments by program year
Who reported the general payments
Companies are grouped under their corporate parent — a single manufacturer often files under several CMS reporting entities. Research and ownership payments are counted separately and are not in this table.

| Bayer | 18 | $11,848 |
| Astrazeneca UK Limited | 2 | $6,881 |
| Eli Lilly | 1 | $2,750 |
What the payments were tied to
Products named in the reported payments. Only payments of $100 or more are attributed here — the typical reported payment nationally is a meal worth about $16, and listing those product-by-product would be noise.
How this compares
$55,164 in reported general payments places this provider in the 95th percentile of 285 nephrology providers in Maryland.
