Payments from drug & device makers
What this record shows
This record is dominated by consulting fees: $6,660 of the $10,311 with a category attached, or 64.6%. Novartis accounts for 90.4% of it on its own, with 1 other manufacturer making up the rest. Among pediatric hematology-oncology clinicians in MD with any reported payments, this total sits in the top 10% — high for the specialty, which is a reason to read the composition above rather than the number alone.
Across 21 payments — averaging $491.01 each. Meals, travel, consulting and speaking fees, gifts and royalties reported by drug and device makers.
- Novartis$9K
- CSL Behring$992
Across 8 payments — averaging $370,271 each. Payments tied to a research study. These frequently flow through the physician to a hospital or research institution rather than to the physician personally.

Who reported the general payments

| CSL Behring | 8 | $992 |
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.
