Payments from drug & device makers
What this record shows
This record is dominated by royalties or licence payments: $4,435,660 of the $5,421,548 with a category attached, or 81.8%. Stryker accounts for 98.5% of it on its own, with 17 other manufacturers making up the rest. 2025 is the largest year on record at $2,006,684, 5.4 times the $375,017 reported in 2019. 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.
Across 827 payments — averaging $6555.68 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
$5,421,548 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.
