Payments from drug & device makers
What this record shows
Almost everything reported here is food and beverage — 100.0% of the total across 11 separate payments, which is the pattern of a clinician who attends manufacturer presentations rather than one with a consulting arrangement. 4 manufacturers reported payments, led by Exact Sciences at 53.1% of the total. 2025 is the largest year on record at $143, more than ten times the $13 reported in 2021.
Across 11 payments — averaging $22.79 each. Meals, travel, consulting and speaking fees, gifts and royalties reported by drug and device makers.
- Exact Sciences$133
- GSK$86
- AstraZeneca$19
- ZOLL Services LLC (a/k/a ZOLL Lifecor Corp)$13
Across 27 payments — averaging $10,084 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.
- Janssen Research & Development, LLC$272K
What the payments were for
- Food & beverage$251100%
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 |
|---|---|---|
| Exact Sciences | 5 | $133 |
| GSK | 4 | $86 |
| AstraZeneca | 1 | $19 |
| ZOLL Services LLC (a/k/a ZOLL Lifecor Corp) | 1 | $13 |
How this compares
$251 in reported general payments places this provider in the 55th percentile of 4,567 internal medicine 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.
