No. Federal law requires drug and device makers to report almost every transfer of value to a physician, including a $14 sandwich at a lunch presentation. Consulting fees, research funding and royalties to device inventors are ordinary, legal parts of medicine. This site reports what was disclosed; it makes no allegation.

Payments from drug & device makers

What this record shows

This record is dominated by travel and lodging: $10,259 of the $15,038 with a category attached, or 68.2%. It is spread thinly across 9 manufacturers, the largest accounting for just 17.9%. Reporting peaked in 2019 at $5,627 and has fallen 54.8% since, to $2,543 in 2025. Among internal medicine clinicians in IN 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.
