Payments from drug & device makers
What this record shows
The money is spread across several categories — speaking fees (54.2%), travel and lodging and food and beverage — rather than concentrated in one kind of arrangement. Microvention, Inc. accounts for 79.9% of it on its own, with 17 other manufacturers making up the rest. 2025 is the largest year on record at $136,098, more than ten times the $10,632 reported in 2019. Among neurological surgery clinicians in NY 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 455 payments — averaging $456.70 each. Meals, travel, consulting and speaking fees, gifts and royalties reported by drug and device makers.

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
$207,798 in reported general payments places this provider in the 90th percentile of 446 neurological surgery providers in New York.
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.
