Payments from drug & device makers
What this record shows
This record is dominated by food and beverage: $19,528 of the $24,907 with a category attached, or 78.4%. It is spread thinly across 30 manufacturers, the largest accounting for just 16.9% — the pattern of someone who eats at a lot of different presentations. Among dermatology clinicians in CA with any reported payments, this total sits in the top 10% — high for the specialty, which is a reason to read the composition above rather than the number alone.
Across 845 payments — averaging $29.48 each. Meals, travel, consulting and speaking fees, gifts and royalties reported by drug and device makers.
- EPI Health, LLC$4K
- AbbVie$4K
- Ortho Dermatologics, A Division Of Bausch Health US, LLC$3K
- Sun Pharmaceutical Industries Inc.$2K
- Galderma Laboratories, L.p.$2K
- Incyte Corporation$1K
- plus $9K from 24 others
Across 83 payments — averaging $1062.51 each. Payments tied to a research study. These frequently flow through the physician to a hospital or research institution rather than to the physician personally.

- Dermavant Sciences, Inc.$20K
- Eli Lilly$14K
- Incyte Corporation$8K
- Taro Pharmaceuticals USA, Inc.$8K

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.

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
$24,907 in reported general payments places this provider in the 90th percentile of 1,875 dermatology providers in California.
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 |
|---|---|---|
| Clobetasol Propionate | 12 | $1,658 |
| Tretinoin | 11 | $512 |
| Ketoconazole | 18 | $508 |
| Triamcinolone Acetonide | 21 | $381 |
| Minoxidil | 17 | $213 |
| Mometasone Furoate | 17 | $187 |
