Payments from drug & device makers
What this record shows
Almost everything reported here is food and beverage — 100.0% of the total across 17 separate payments, which is the pattern of a clinician who attends manufacturer presentations rather than one with a consulting arrangement. 10 manufacturers reported payments, led by Novo Nordisk at 33.5% of the total. Reporting peaked in 2024 at $189 and has fallen 89.3% since, to $20 in 2025. That places this record below the midpoint for surgery clinicians in NC, where the typical reported total is $1,719.

How this compares
$315 in reported general payments places this provider in the 25th percentile of 970 surgery providers in North Carolina.
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 |
|---|---|---|
| Pantoprazole Sodium | 62 | $483 |
| Hydrocodone-AcetaminophenHydrocodone/Acetaminophen | 30 | $204 |
| Metronidazole | 12 | $86 |
| Ondansetron OdtOndansetron | 11 | $66 |
