Payments from drug & device makers
What this record shows
Almost everything reported here is food and beverage — 100.0% of the total across 38 separate payments, which is the pattern of a clinician who attends manufacturer presentations rather than one with a consulting arrangement. Stryker accounts for 69.2% of it on its own, with 3 other manufacturers making up the rest. 2025 is the largest year on record at $294, 4.3 times the $69 reported in 2019. Among emergency medicine clinicians in CA 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 38 payments — averaging $11.17 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 |
|---|---|---|
| Stryker | 30 | $294 |
| Pfizer | 5 | $75 |
| AbbVie(2 entities) | 2 | $37 |
| Inari Medical, Inc. | 1 | $19 |
How this compares
$425 in reported general payments places this provider in the 90th percentile of 6,006 emergency medicine 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 |
|---|---|---|
| Nitrofurantoin Mono-MacroNitrofurantoin Monohyd/M-Cryst | 20 | $246 |
| Clindamycin Hcl | 12 | $88 |
| Sulfamethoxazole-TrimethoprimSulfamethoxazole/Trimethoprim | 19 | $81 |
