Payments from drug & device makers
What this record shows
Almost everything reported here is food and beverage — 100.0% of the total across 42 separate payments, which is the pattern of a clinician who attends manufacturer presentations rather than one with a consulting arrangement. It is spread thinly across 20 manufacturers, the largest accounting for just 23.4% — the pattern of someone who eats at a lot of different presentations. Reporting peaked in 2019 at $1,105 and has fallen 81.5% since, to $205 in 2025.
Across 42 payments — averaging $50.69 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 |
|---|---|---|
| UCB, Inc. | 7 | $498 |
| Jazz Pharmaceuticals Inc. | 5 | $423 |
| Alnylam Pharmaceuticals Inc. | 4 | $204 |
| AstraZeneca | 2 | $127 |
| Alkermes, Inc. | 1 | $125 |
| Greenwich Biosciences, Inc. | 1 | $125 |
| Teva Pharmaceuticals USA, Inc. | 3 | $122 |
| Lilly USA, LLC | 2 | $92 |
| SK Life Science, Inc. | 3 | $81 |
| Acorda Therapeutics, Inc | 1 | $68 |

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
$2,129 in reported general payments places this provider in the 75th percentile of 30 epilepsy providers in Michigan.
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 |
|---|---|---|
| UCB, Inc.Briviact, Vimpat | $498 | $96,87653 claims |
| SK Life Science, Inc.Xcopri | $81 | $12,05711 claims |
| Upsher-smith Laboratories LLCTopiramate | $29 | $33525 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 75th percentile of 30 epilepsy providers in Michigan.
