Payments from drug & device makers

What this record shows

This record is dominated by consulting fees: $443,380 of the $600,626 with a category attached, or 73.8%. Stryker accounts for 61.3% of it on its own, with 16 other manufacturers making up the rest. Among orthopaedic surgery 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.

Medicare billing

Part B allowed, 2024

$180,211

Medicare patients

278

Services billed

4,595

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.
