Payments from drug & device makers
What this record shows
The money is spread across several categories — consulting fees (49.9%), food and beverage and grants — rather than concentrated in one kind of arrangement. W. L. Gore & Associates, Inc. accounts for 75.4% of it on its own, with 8 other manufacturers making up the rest. Reporting peaked in 2023 at $2,124 and has fallen 82.5% since, to $372 in 2025. That places this record below the midpoint for vascular surgery clinicians in CA, where the typical reported total is $3,945.
Across 23 payments — averaging $149.07 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

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
$3,429 in reported general payments places this provider in the 45th percentile of 519 vascular surgery 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 |

Paid to pharmacies, not to this prescriber.
