Payments from drug & device makers
What this record shows
Almost everything reported here is food and beverage — 98.0% of the total across 356 separate payments, which is the pattern of a clinician who attends manufacturer presentations rather than one with a consulting arrangement. 28 manufacturers reported payments, led by Amgen at 28.9% of the total. Reporting peaked in 2023 at $2,392 and has fallen 94.3% since, to $136 in 2025.
Across 356 payments — averaging $19.69 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
$7,011 in reported general payments places this provider in the 75th percentile of 108 rheumatology providers in Colorado.
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.
