Payments from drug & device makers
What this record shows
Almost everything reported here is food and beverage — 100.0% of the total across 14 separate payments, which is the pattern of a clinician who attends manufacturer presentations rather than one with a consulting arrangement. It is spread thinly across 8 manufacturers, the largest accounting for just 23.0% — the pattern of someone who eats at a lot of different presentations. Reporting peaked in 2019 at $145 and has fallen 87.1% since, to $19 in 2024. That places this record below the midpoint for surgical oncology clinicians in NJ, where the typical reported total is $1,132.
Across 14 payments — averaging $17.27 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.
| Company | Payments | Total |
|---|---|---|
| Novartis | 3 | $56 |
| Seagen Inc. | 3 | $44 |
| Hologic Inc | 2 | $37 |
| GE HealthCare | 1 | $34 |
| Merck | 2 | $26 |
| Leica Microsystems Inc. | 1 | $19 |
| Partner Therapeutics, Inc. | 1 | $15 |
| Foundation Medicine, Inc. | 1 | $12 |
How this compares
$242 in reported general payments places this provider in the 15th percentile of 59 surgical oncology 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.
Most prescribed under Part D
| Drug | Claims | Cost to plans & patients |
|---|---|---|
| Oxycodone-AcetaminophenOxycodone Hcl/Acetaminophen | 27 | $81 |
Paid to pharmacies, not to this prescriber.
