Payments from drug & device makers
What this record shows
Almost everything reported here is food and beverage — 100.0% of the total across 76 separate payments, which is the pattern of a clinician who attends manufacturer presentations rather than one with a consulting arrangement. AbbVie accounts for 68.5% of it on its own, with 7 other manufacturers making up the rest. Reporting peaked in 2021 at $397 and has fallen 94.2% since, to $23 in 2025. Among hospitalist clinicians in CA 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.
Across 76 payments — averaging $22.89 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 |
|---|---|---|
| AbbVie(2 entities) | 51 | $1,192 |
| ZOLL Services LLC (a/k/a ZOLL Lifecor Corp) | 11 | $249 |
| Pfizer | 4 | $104 |
| Novartis | 5 | $98 |
| Takeda Pharmaceuticals U.S.A., Inc. | 1 | $29 |
| AstraZeneca | 2 | $27 |
| Johnson & Johnson | 1 | $25 |

How this compares
$1,739 in reported general payments places this provider in the 95th percentile of 2,469 hospitalist 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 |
|---|---|---|
| Amoxicillin-Clavulanate PotassAmoxicillin/Potassium Clav | 11 | $221 |
| Amlodipine Besylate | 16 | $88 |
| Hydrocodone-AcetaminophenHydrocodone/Acetaminophen | 15 | $87 |
