Payments from drug & device makers
What this record shows
This record is dominated by speaking fees: $4,311 of the $5,507 with a category attached, or 78.3%. Organogenesis Inc. accounts for 86.0% of it on its own, with 9 other manufacturers making up the rest. Reporting peaked in 2019 at $3,769 and has fallen 89.7% since, to $387 in 2025. Among foot surgery clinicians in MA 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 39 payments — averaging $141.22 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
$5,507 in reported general payments places this provider in the 90th percentile of 41 foot surgery providers in Massachusetts.
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.

| Econazole Nitrate | 17 | $863 |
