Payments from drug & device makers
What this record shows
This record is dominated by consulting fees: $14,687 of the $14,687 with a category attached, or 100.0%. Shire North American Group Inc accounts for 88.0% of it on its own, with 1 other manufacturer making up the rest. Among emergency medicine clinicians in FL 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.
Across 4 payments — averaging $3671.75 each. Meals, travel, consulting and speaking fees, gifts and royalties reported by drug and device makers.
- Shire North American Group Inc$13K
- Novartis Pharma AG$2K
Across 17 payments — averaging $7559.76 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.
- Incyte Corporation$129K
What the payments were for

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 |
|---|---|---|
| Shire North American Group Inc | 3 | $12,931 |
| Novartis Pharma AG | 1 | $1,756 |
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.
- MAYZENT$1,756
How this compares
$14,687 in reported general payments places this provider in the 95th percentile of 3,289 emergency medicine providers in Florida.
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.
