What this record shows
8 manufacturers reported payments, led by AstraZeneca at 33.6% of the total. 2025 is the largest year on record at $132, 8.1 times the $16 reported in 2023. That places this record below the midpoint for neurology clinicians in SC, where the typical reported total is $752.
Across 10 payments — averaging $22.30 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 |
|---|---|---|
| AstraZeneca | 1 | $75 |
| AbbVie | 3 | $43 |
| Neurelis, Inc. | 1 | $22 |
| Amgen | 1 | $20 |
| EMD Serono, Inc. | 1 | $18 |
| Cala Health, Inc. | 1 | $16 |
| TG Therapeutics, Inc. | 1 | $15 |
| Otsuka America Pharmaceutical, Inc. | 1 | $15 |
How this compares
$223 in reported general payments places this provider in the 30th percentile of 270 neurology providers in South Carolina.
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.
Most prescribed under Part D

Paid to pharmacies, not to this prescriber.
Companies that both paid and supply prescribed drugs
These companies both reported payments to this provider and make drugs the provider prescribed under Medicare Part D in 2024. For most specialties this overlap is expected — a cardiologist who is paid by a cardiology drugmaker also treats heart disease. It is shown so the reader can see it, not because it implies anything on its own.
| Company | Paid to this provider | Part D cost of their drugs |
|---|---|---|
| AbbVieQulipta | $43 | $24,57123 claims |
Reading this fairly. The Part D column is what drug plans and patients paid pharmacies — this provider received none of it, and it reflects how many patients they treat and what those drugs cost. Against peers, this provider's reported payments sit in the 30th percentile of 270 neurology providers in South Carolina.
