Payments from drug & device makers
What this record shows
Almost everything reported here is food and beverage — 92.7% of the total across 443 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 31 manufacturers, the largest accounting for just 22.7% — the pattern of someone who eats at a lot of different presentations.
Across 443 payments — averaging $27.79 each. Meals, travel, consulting and speaking fees, gifts and royalties reported by drug and device makers.
- AbbVie$3K
- Johnson & Johnson$2K
- Regeneron Healthcare Solutions, Inc.$1K
- Pfizer$895
- Janssen Scientific Affairs, LLC$881
- Sanofi$845

Across 2 payments — averaging $2000.00 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.

What the payments were for
- Speaking & faculty fees$3503%
- Food & beverage$11,41393%

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
$12,309 in reported general payments places this provider in the 80th percentile of 209 dermatology providers in Tennessee.
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.
