Payments from drug & device makers
What this record shows
Almost everything reported here is food and beverage — 100.0% of the total across 32 separate payments, which is the pattern of a clinician who attends manufacturer presentations rather than one with a consulting arrangement. Sun Pharmaceutical Industries Inc. accounts for 65.7% of it on its own, with 5 other manufacturers making up the rest. Reporting peaked in 2021 at $224 and has fallen 69.8% since, to $68 in 2025. That places this record below the midpoint for surgery clinicians in MA, where the typical reported total is $1,048.
Across 32 payments — averaging $18.84 each. Meals, travel, consulting and speaking fees, gifts and royalties reported by drug and device makers.

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.

How this compares
$603 in reported general payments places this provider in the 40th percentile of 694 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.
