Payments from drug & device makers
What this record shows
The money is spread across several categories — food and beverage (57.3%), travel and lodging and education — rather than concentrated in one kind of arrangement. Biotronik Inc. accounts for 84.7% of it on its own, with 7 other manufacturers making up the rest. Reporting peaked in 2020 at $1,333 and has fallen 98.0% since, to $27 in 2022. That places this record below the midpoint for pain medicine clinicians in NY, where the typical reported total is $1,573.
Across 30 payments — averaging $52.99 each. Meals, travel, consulting and speaking fees, gifts and royalties reported by drug and device makers.

Who reported the general payments

How this compares
$1,590 in reported general payments places this provider in the 50th percentile of 503 pain medicine 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.
