Payments from drug & device makers
What this record shows
This record is dominated by food and beverage: $3,142 of the $4,141 with a category attached, or 75.9%. It is spread thinly across 23 manufacturers, the largest accounting for just 16.0% — the pattern of someone who eats at a lot of different presentations.
Across 66 payments — averaging $62.74 each. Meals, travel, consulting and speaking fees, gifts and royalties reported by drug and device makers.

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.
