Payments from drug & device makers
What this record shows
This record is dominated by speaking fees: $96,560 of the $113,817 with a category attached, or 84.8%. AbbVie accounts for 91.7% of it on its own, with 25 other manufacturers making up the rest. Reporting peaked in 2021 at $42,907 and has fallen 99.0% since, to $432 in 2025. Among internal medicine clinicians in NH 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 265 payments — averaging $429.50 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
$113,817 in reported general payments places this provider in the 95th percentile of 504 internal medicine providers in New Hampshire.
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.
