Payments from drug & device makers
What this record shows
The money is spread across several categories — food and beverage (59.1%), travel and lodging and consulting fees — rather than concentrated in one kind of arrangement. It is spread thinly across 24 manufacturers, the largest accounting for just 21.8%. 2025 is the largest year on record at $4,476, more than ten times the $140 reported in 2019.
Across 56 payments — averaging $224.48 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

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
$12,571 in reported general payments places this provider in the 70th 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.
Most prescribed under Part D
| Drug | Claims | Cost to plans & patients |
|---|---|---|
| Methylprednisolone | 12 | $69 |
Paid to pharmacies, not to this prescriber.
