Payments from drug & device makers
What this record shows
This record is dominated by food and beverage: $2,318 of the $3,851 with a category attached, or 60.2%. Medtronic accounts for 65.1% of it on its own, with 14 other manufacturers making up the rest. 2025 is the largest year on record at $2,107, 6.2 times the $343 reported in 2019. Among anesthesiology 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 61 payments — averaging $63.14 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
Companies are grouped under their corporate parent — a single manufacturer often files under several CMS reporting entities. Research and ownership payments are counted separately and are not in this table.

|---|---|---|
| Medtronic | 31 | $2,508 |
| SPR Therapeutics, Inc | 3 | $286 |
| Globus Medical | 4 | $229 |

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
$3,851 in reported general payments places this provider in the 95th percentile of 1,430 anesthesiology providers in New Jersey.
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.
