Payments from drug & device makers
What this record shows
This record is dominated by consulting fees: $177,710 of the $177,710 with a category attached, or 100.0%. Pfizer accounts for 86.1% of it on its own, with 2 other manufacturers making up the rest. Reporting peaked in 2019 at $160,360 and has fallen 98.5% since, to $2,380 in 2021. Among diagnostic radiology 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.

| Medivation LLC. | 25 | $23,150 |
| Merck | 1 | $1,600 |
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.

$177,710 in reported general payments places this provider in the 95th percentile of 1,206 diagnostic radiology providers in Massachusetts.
