Payments from drug & device makers
What this record shows
This record is dominated by food and beverage: $2,458 of the $3,527 with a category attached, or 69.7%. 10 manufacturers reported payments, led by Si-bone, Inc. at 58.2% of the total. Reporting peaked in 2023 at $1,666 and has fallen 59.1% since, to $682 in 2024. Among physician assistant 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.
Across 27 payments — averaging $130.64 each. Meals, travel, consulting and speaking fees, gifts and royalties reported by drug and device makers.

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.

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.

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.
Most prescribed under Part D
| Drug | Claims | Cost to plans & patients |
|---|---|---|
| Gabapentin | 30 | $279 |
| Oxycodone Hcl | 32 | $186 |
| Ondansetron Hcl | 26 | $129 |
| Hydrocodone-AcetaminophenHydrocodone/Acetaminophen | 13 | $60 |
| Meloxicam | 16 | $55 |
| Amoxicillin | 22 | $17 |
