Payments from drug & device makers
What this record shows
Almost everything reported here is food and beverage — 93.8% of the total across 77 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 24 manufacturers, the largest accounting for just 15.4% — the pattern of someone who eats at a lot of different presentations. 2025 is the largest year on record at $548, 3.0 times the $182 reported in 2019. That places this record below the midpoint for dermatology clinicians in NJ, where the typical reported total is $1,986.
Across 77 payments — averaging $18.06 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
$1,390 in reported general payments places this provider in the 40th percentile of 394 dermatology 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 |

| Dupixent PenDupilumab | 11 | $43,170 |
| Clobetasol Propionate | 32 | $1,357 |
| Desonide | 15 | $667 |
| Triamcinolone Acetonide | 31 | $615 |
