Payments from drug & device makers
What this record shows
Almost everything reported here is food and beverage — 100.0% of the total across 15 separate payments, which is the pattern of a clinician who attends manufacturer presentations rather than one with a consulting arrangement. 8 manufacturers reported payments, led by Genentech USA, Inc. at 25.5% of the total. Reporting peaked in 2022 at $115 and has fallen 51.1% since, to $56 in 2024. That places this record below the midpoint for physician assistant clinicians in CA, where the typical reported total is $226.
Across 15 payments — averaging $17.37 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.
| Company | Payments | Total |
|---|---|---|
| Genentech USA, Inc. | 5 | $66 |
| Amgen | 3 | $45 |
| Merck | 2 | $38 |
| AstraZeneca | 1 | $29 |
| Solventum Corporation | 1 | $27 |
| Incyte Corporation | 1 | $26 |
| Seagen Inc. | 1 | $15 |
| EMD Serono, Inc. | 1 | $13 |
How this compares
$261 in reported general payments places this provider in the 50th percentile of 10,423 physician assistant providers in California.
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 |
|---|---|---|
| EliquisApixaban | 13 | $7,396 |
| Oxycodone Hcl | 44 | $209 |
| Ibuprofen | 11 | $42 |
Paid to pharmacies, not to this prescriber.
