Does a payment mean Garrett Diltz did something wrong?

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

Almost everything reported here is food and beverage — 92.7% of the total across 96 separate payments, which is the pattern of a clinician who attends manufacturer presentations rather than one with a consulting arrangement. It is spread thinly across 45 manufacturers, the largest accounting for just 9.5% — the pattern of someone who eats at a lot of different presentations. 2025 is the largest year on record at $2,274, 2.5 times the $920 reported in 2022. That places this record below the midpoint for medical oncology clinicians in MD, where the typical reported total is $4,199.
