Payments from drug & device makers
What this record shows
The money is spread across several categories — education (54.7%), travel and lodging and consulting fees — rather than concentrated in one kind of arrangement. Intuitive Surgical accounts for 88.5% of it on its own, with 3 other manufacturers making up the rest. 2025 is the largest year on record at $4,343, more than ten times the $19 reported in 2019.
Across 12 payments — averaging $422.05 each. Meals, travel, consulting and speaking fees, gifts and royalties reported by drug and device makers.
- Intuitive Surgical$4K
- ZOLL Medical Corporation$525
- Zimmer Biomet$40
- Terumo Medical Corporation$19
Across 5 payments — averaging $6366.21 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.

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 |
|---|---|---|
| Intuitive Surgical | 9 | $4,481 |
| ZOLL Medical Corporation | 1 | $525 |
| Zimmer Biomet | 1 | $40 |
| Terumo Medical Corporation | 1 | $19 |
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.
- DAVINCI XI$2,500
- Da Vinci Surgical System$1,905
- Defibrillator$525
How this compares
$5,065 in reported general payments places this provider in the 70th 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.
