What this record shows
This record is dominated by consulting fees: $797,694 of the $798,309 with a category attached, or 99.9%. Adaptive Biotechnologies Corporation accounts for 63.0% of it on its own, with 7 other manufacturers making up the rest. Among internal medicine clinicians in MA 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.
