Payments from drug & device makers
What this record shows
The money is spread across several categories — speaking fees (58.5%), consulting fees and travel and lodging — rather than concentrated in one kind of arrangement. 4 manufacturers reported payments, led by Kyowa Kirin, Inc. at 52.4% of the total. Among pediatric nephrology clinicians in NC 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 153 payments — averaging $878.62 each. Meals, travel, consulting and speaking fees, gifts and royalties reported by drug and device makers.
- Kyowa Kirin, Inc.$70K
- Ultragenyx Pharmaceutical Inc.$63K
- AstraZeneca$1K
- Masimo Corporation$18
Across 81 payments — averaging $2607.68 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.

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 |
|---|---|---|
| Kyowa Kirin, Inc. | 80 | $70,392 |
| Ultragenyx Pharmaceutical Inc. | 66 | $62,617 |
| AstraZeneca | 6 | $1,401 |
| Masimo Corporation | 1 | $18 |
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
$134,429 in reported general payments places this provider in the 95th percentile of 20 pediatric nephrology providers in North Carolina.
