Payments from drug & device makers
What this record shows
The money is spread across several categories — travel and lodging (58.9%), consulting fees and speaking fees — rather than concentrated in one kind of arrangement. 9 manufacturers reported payments, led by Grifols Biologicals LLC at 40.1% of the total. Reporting peaked in 2019 at $41,689 and has fallen 99.9% since, to $30 in 2025. Among neurology clinicians in PA 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 74 payments — averaging $1312.00 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.

| Novo Nordisk AS | 5 | $21,160 |

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.
- Flebogamma DIF$50,614
- Albutein$48,900
- ADUHELM$1,500
How this compares
$97,088 in reported general payments places this provider in the 90th percentile of 941 neurology providers in Pennsylvania.
Medicare billing
What this is not: this is the amount Original Medicare Part B allowed for services this provider billed in 2024. It is not their income. It excludes Medicare Advantage — now more than half of all Medicare enrollment — along with Medicaid and all commercial insurance, and it is gross practice revenue before staff, rent, supplies and malpractice premiums. CMS also suppresses any figure covering ten or fewer patients, so low-volume providers appear smaller than they are.
