Payments from drug & device makers
What this record shows
The money is spread across several categories — travel and lodging (34.8%), consulting fees and speaking fees — rather than concentrated in one kind of arrangement. Encore Medical, LP accounts for 81.2% of it on its own, with 11 other manufacturers making up the rest. Among orthopaedic surgery clinicians in ME with any reported payments, this total sits in the top 10% — high for the specialty, which is a reason to read the composition above rather than the number alone.
Across 119 payments — averaging $313.11 each. Meals, travel, consulting and speaking fees, gifts and royalties reported by drug and device makers.

How this compares
$37,260 in reported general payments places this provider in the 90th 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.
