Payments from drug & device makers
What this record shows
This record is dominated by consulting fees: $100,228 of the $155,529 with a category attached, or 64.4%. 15 manufacturers reported payments, led by Carbofix Orthopedics Inc at 38.0% of the total. Reporting peaked in 2023 at $62,086 and has fallen 53.7% since, to $28,741 in 2025. Among orthopaedic surgery clinicians in MA 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.

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
$155,529 in reported general payments places this provider in the 95th percentile of 542 orthopaedic 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.
