Payments from drug & device makers
What this record shows
This record is dominated by speaking fees: $24,613 of the $37,099 with a category attached, or 66.3%. 6 manufacturers reported payments, led by CSL Behring at 25.7% of the total. Reporting peaked in 2024 at $20,687 and has fallen 85.2% since, to $3,058 in 2025. Among gastroenterology clinicians in DC with any reported payments, this total sits in the top 10% — 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.
| Company | Payments | Total |
|---|---|---|
| CSL Behring | 6 | $9,531 |
| Salix Pharmaceuticals, A Division Of Bausch Health US, LLC | 8 | $8,936 |
| Spark Therapeutics, Inc. | 4 | $7,108 |
| Sanofi | 1 | $5,150 |
| Biomarin Pharmaceutical Inc. | 5 | $4,374 |
| Pfizer | 2 | $2,000 |
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
$37,099 in reported general payments places this provider in the 90th percentile of 77 gastroenterology providers in District of Columbia.

Medicare billing
What this is not: this is the amount Original Medicare Part B allowed for services this provider billed in 2024. It is not their income. It excludes Medicare Advantage — now more than half of all Medicare enrollment — along with Medicaid and all commercial insurance, and it is gross practice revenue before staff, rent, supplies and malpractice premiums. CMS also suppresses any figure covering ten or fewer patients, so low-volume providers appear smaller than they are.
