Payments from drug & device makers
What this record shows
Almost everything reported here is food and beverage — 91.8% of the total across 62 separate payments, which is the pattern of a clinician who attends manufacturer presentations rather than one with a consulting arrangement. 11 manufacturers reported payments, led by Biogen at 39.4% of the total. Reporting peaked in 2019 at $437 and has fallen 93.0% since, to $30 in 2022. That places this record below the midpoint for neurology clinicians in MI, where the typical reported total is $1,115.
Across 62 payments — averaging $9.15 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

| Biogen | 44 | $224 |
| Sanofi | 4 | $79 |

How this compares
$568 in reported general payments places this provider in the 40th percentile of 652 neurology 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.
