Payments from drug & device makers
What this record shows
This record is dominated by food and beverage: $1,370 of the $1,698 with a category attached, or 80.7%. It is spread thinly across 22 manufacturers, the largest accounting for just 21.9% — the pattern of someone who eats at a lot of different presentations. 2025 is the largest year on record at $965, more than ten times the $35 reported in 2021. That places this record below the midpoint for urology clinicians in CT, where the typical reported total is $1,704.
Across 60 payments — averaging $28.29 each. Meals, travel, consulting and speaking fees, gifts and royalties reported by drug and device makers.

How this compares
$1,698 in reported general payments places this provider in the 45th percentile of 156 urology providers in Connecticut.
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.
