Payments from drug & device makers
What this record shows
This record is dominated by food and beverage: $3,751 of the $4,700 with a category attached, or 79.8%. 11 manufacturers reported payments, led by Nevro Corp. at 52.3% of the total. Reporting peaked in 2019 at $2,032 and has fallen 95.4% since, to $94 in 2025. Among anesthesiology clinicians in MI with any reported payments, this total sits in the top 5% — high for the specialty, which is a reason to read the composition above rather than the number alone.
Across 72 payments — averaging $65.28 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

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
$4,700 in reported general payments places this provider in the 95th 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.
Most prescribed under Part D
| Drug | Claims | Cost to plans & patients |
|---|---|---|
| Gabapentin | 111 | $1,528 |
| Baclofen | 25 | $464 |
| Duloxetine Hcl | 21 | $374 |
| Memantine Hcl | 27 | $318 |
| Pregabalin | 14 | $259 |
| Cyclobenzaprine Hcl | 36 | $146 |
| Methocarbamol | 14 | $124 |
