Payments from drug & device makers
What this record shows
This record is dominated by consulting fees: $7,150 of the $8,675 with a category attached, or 82.4%. Roche Diagnostics Corporation accounts for 96.5% of it on its own, with 2 other manufacturers making up the rest. Among emergency medicine clinicians in PA 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.
Across 14 payments — averaging $619.66 each. Meals, travel, consulting and speaking fees, gifts and royalties reported by drug and device makers.

General payments by program year
Who reported the general payments
Companies are grouped under their corporate parent — a single manufacturer often files under several CMS reporting entities. Research and ownership payments are counted separately and are not in this table.
| Company | Payments | Total |
|---|---|---|
| Roche Diagnostics Corporation | 9 | $8,368 |
| Quidel Corporation | 1 | $200 |
| Johnson & Johnson | 4 | $107 |
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.
How this compares
$8,675 in reported general payments places this provider in the 95th percentile of 3,120 emergency medicine providers in Pennsylvania.
