Payments from drug & device makers
What this record shows
This record is dominated by travel and lodging: $1,110 of the $1,581 with a category attached, or 70.2%. Every reported general payment came from a single manufacturer, Edwards Lifesciences. Reporting peaked in 2022 at $1,484 and has fallen 95.8% since, to $62 in 2023. Among anesthesiology clinicians in MI with any reported payments, this total sits in the top 10% — high for the specialty, which is a reason to read the composition above rather than the number alone.
Across 15 payments — averaging $105.41 each. Meals, travel, consulting and speaking fees, gifts and royalties reported by drug and device makers.
- Edwards Lifesciences$2K
Across 36 payments — averaging $24,116 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.

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 |
|---|---|---|
| Edwards Lifesciences | 15 | $1,581 |
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.
- HemoSphere$1,152
How this compares
$1,581 in reported general payments places this provider in the 90th percentile of 1,299 anesthesiology 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.
