What this record shows

Reporting peaked in 2019 at $41,061 and has fallen 94.8% since, to $2,139 in 2022. Among medical oncology clinicians in CO with any reported payments, this total sits in the top 10% — high for the specialty, which is a reason to read the composition above rather than the number alone.
