Payments from drug & device makers
What this record shows

Smith+Nephew accounts for 85.3% of it on its own, with 8 other manufacturers making up the rest. Reporting peaked in 2021 at $11,523 and has fallen 92.2% since, to $896 in 2025.
Across 114 payments — averaging $227.53 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
$25,938 in reported general payments places this provider in the 85th percentile of 111 orthopaedic surgery providers in Maine.
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.
