Payments from drug & device makers
What this record shows
This record is dominated by food and beverage: $7,481 of the $8,315 with a category attached, or 90.0%. It is spread thinly across 25 manufacturers, the largest accounting for just 12.9% — the pattern of someone who eats at a lot of different presentations. Among surgical 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 342 payments — averaging $24.31 each. Meals, travel, consulting and speaking fees, gifts and royalties reported by drug and device makers.

What the payments were for
- Food & beverage$7,48190%

Most of this is food and beverage — typically meals provided during product presentations at a clinic or hospital. Nationally that is the single largest category of reported payments by count.
General payments by program year

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.
How this compares
$8,315 in reported general payments places this provider in the 95th percentile of 729 surgical 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.

| Ketoconazole | 107 | $2,038 |

| Tacrolimus | 11 | $1,031 |
