Payments from drug & device makers
What this record shows
Almost everything reported here is food and beverage — 100.0% of the total across 7 separate payments, which is the pattern of a clinician who attends manufacturer presentations rather than one with a consulting arrangement. Medical Device Business Services, Inc. accounts for 71.2% of it on its own, with 4 other manufacturers making up the rest. Reporting peaked in 2022 at $139 and has fallen 73.3% since, to $37 in 2025. That places this record below the midpoint for hand surgery clinicians in AL, where the typical reported total is $2,588.
Across 7 payments — averaging $47.11 each. Meals, travel, consulting and speaking fees, gifts and royalties reported by drug and device makers.

How this compares
$330 in reported general payments places this provider in the 10th percentile of 29 hand surgery providers in Alabama.
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 |
|---|---|---|
| Hydrocodone-AcetaminophenHydrocodone/Acetaminophen | 147 | $598 |
| Oxycodone-AcetaminophenOxycodone Hcl/Acetaminophen | 26 | $100 |
| Cephalexin | 50 | $95 |
| Gabapentin | 25 | $82 |
