Payments from drug & device makers

What this record shows

This record is dominated by speaking fees: $38,271 of the $45,009 with a category attached, or 85.0%. Sanofi accounts for 75.7% of it on its own, with 19 other manufacturers making up the rest. 2025 is the largest year on record at $17,610, more than ten times the $476 reported in 2019. Among otolaryngology clinicians in CO 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.

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.

Medicare billing

Part B allowed, 2024
$306,385
Medicare patients
493
Services billed
1,659

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.
