Payments from drug & device makers
What this record shows
This record is dominated by consulting fees: $40,750 of the $53,039 with a category attached, or 76.8%. Dilon Technologies, Inc. accounts for 94.2% of it on its own, with 17 other manufacturers making up the rest. 2025 is the largest year on record at $44,456, more than ten times the $271 reported in 2019. Among surgery clinicians in NJ 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 94 payments — averaging $564.25 each. Meals, travel, consulting and speaking fees, gifts and royalties reported by drug and device makers.

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.
