Payments from drug & device makers
What this record shows
Almost everything reported here is food and beverage — 100.0% of the total across 4 separate payments, which is the pattern of a clinician who attends manufacturer presentations rather than one with a consulting arrangement. Johnson & Johnson accounts for 67.5% of it on its own, with 2 other manufacturers making up the rest. 2024 is the largest year on record at $130, 5.2 times the $25 reported in 2022. That places this record below the midpoint for pulmonary disease clinicians in DC, where the typical reported total is $785.
Across 4 payments — averaging $48.15 each. Meals, travel, consulting and speaking fees, gifts and royalties reported by drug and device makers.
- Johnson & Johnson$130
- GSK$38
- Intuitive Surgical$25
Across 17 payments — averaging $7449.07 each. Payments tied to a research study. These frequently flow through the physician to a hospital or research institution rather than to the physician personally.

- Takeda Pharmaceuticals U.S.A., Inc.$12K
- Amgen$11K
What the payments were for

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 |
|---|---|---|
| Johnson & Johnson | 1 | $130 |
| GSK | 2 | $38 |
| Intuitive Surgical | 1 | $25 |
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.
- Tremfya$130
How this compares
$193 in reported general payments places this provider in the 35th percentile of 56 pulmonary disease 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.
