Payments from drug & device makers
What this record shows
Almost everything reported here is food and beverage — 100.0% of the total across 76 separate payments, which is the pattern of a clinician who attends manufacturer presentations rather than one with a consulting arrangement. It is spread thinly across 27 manufacturers, the largest accounting for just 19.9% — the pattern of someone who eats at a lot of different presentations. Reporting peaked in 2021 at $1,100 and has fallen 69.7% since, to $333 in 2025. That places this record below the midpoint for thoracic surgery (cardiothoracic vascular surgery) clinicians in IA, where the typical reported total is $2,703.
Across 76 payments — averaging $43.05 each. Meals, travel, consulting and speaking fees, gifts and royalties reported by drug and device makers.

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.

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.
