What this record shows

Regeneron Healthcare Solutions, Inc. accounts for 61.9% of it on its own, with 30 other manufacturers making up the rest. 2025 is the largest year on record at $59,608, more than ten times the $14 reported in 2019. Among dermatology 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.

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
$132,723 in reported general payments places this provider in the 95th 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 |
|---|---|---|
| Cosentyx Unoready PenSecukinumab | 12 | $83,557 |
| Ketoconazole | 16 | $404 |
