Payments from drug & device makers
What this record shows
Almost everything reported here is food and beverage — 100.0% of the total across 167 separate payments, which is the pattern of a clinician who attends manufacturer presentations rather than one with a consulting arrangement. 18 manufacturers reported payments, led by Johnson & Johnson at 27.8% of the total. Reporting peaked in 2024 at $913 and has fallen 79.2% since, to $190 in 2025. Among hospitalist clinicians in PA 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 167 payments — averaging $18.71 each. Meals, travel, consulting and speaking fees, gifts and royalties reported by drug and device makers.

How this compares
$3,124 in reported general payments places this provider in the 95th percentile of 1,287 hospitalist providers in Pennsylvania.
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.
