Payments from drug & device makers
What this record shows
This record is dominated by speaking fees: $197,041 of the $306,233 with a category attached, or 64.3%. Sanofi accounts for 87.6% of it on its own, with 6 other manufacturers making up the rest. Among internal medicine clinicians in MI 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.
