Payments from drug & device makers
What this record shows
Almost everything reported here is food and beverage — 96.3% of the total across 33 separate payments, which is the pattern of a clinician who attends manufacturer presentations rather than one with a consulting arrangement. AbbVie accounts for 63.3% of it on its own, with 8 other manufacturers making up the rest. 2025 is the largest year on record at $283, 2.7 times the $105 reported in 2019. That places this record below the midpoint for neurology clinicians in DC, where the typical reported total is $1,102.
Across 33 payments — averaging $23.02 each. Meals, travel, consulting and speaking fees, gifts and royalties reported by drug and device makers.
- AbbVie$481
- Avanir Pharmaceuticals, Inc.$87
- Takeda Pharmaceuticals U.S.A., Inc.$56
- Amylyx Pharmaceuticals, Inc.$39
- Tanabe Pharma America, Inc.$28

Across 20 payments — averaging $6845.06 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.

- Mallinckrodt Enterprises LLC$23K
- Mallinckrodt Hospital Products Inc.$1K
What the payments were for
- Food & beverage$73196%
- Education$284%
Most of this is food and beverage — typically meals provided during product presentations at a clinic or hospital. Nationally that is the single largest category of reported payments by count.
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 |
|---|---|---|
| AbbVie(2 entities) | 22 | $481 |
| Avanir Pharmaceuticals, Inc. | 3 | $87 |
| Takeda Pharmaceuticals U.S.A., Inc. | 2 | $56 |
| Amylyx Pharmaceuticals, Inc. | 1 | $39 |
| Tanabe Pharma America, Inc. | 1 | $28 |
| Novartis | 1 | $19 |
| Teva Pharmaceuticals USA, Inc. | 1 | $17 |

How this compares
$760 in reported general payments places this provider in the 45th percentile of 113 neurology providers in District of Columbia.
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.

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 |
|---|---|---|
| Amylyx Pharmaceuticals, Inc.Relyvrio | $39 | $331,49825 claims |
| Avanir Pharmaceuticals, Inc.Nuedexta | $87 | $39,21015 claims |
| AbbVieLinzess | $481 | $13,20320 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 45th percentile of 113 neurology providers in District of Columbia.
