Payments from drug & device makers
What this record shows
Almost everything reported here is food and beverage — 100.0% of the total across 63 separate payments, which is the pattern of a clinician who attends manufacturer presentations rather than one with a consulting arrangement. 18 manufacturers reported payments, led by Novo Nordisk at 40.8% of the total. Among emergency medicine clinicians in TN 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 63 payments — averaging $19.96 each. Meals, travel, consulting and speaking fees, gifts and royalties reported by drug and device makers.
- Novo Nordisk$513
- AbbVie$102
- Lundbeck LLC$100
- Axsome Therapeutics, Inc.$96

What the payments were for
- Food & beverage$1,257100%

General payments by program year
Who reported the general payments

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

Paid to pharmacies, not to this prescriber.
Companies that both paid and supply prescribed drugs
These companies both reported payments to this provider and make drugs the provider prescribed under Medicare Part D in 2024. For most specialties this overlap is expected — a cardiologist who is paid by a cardiology drugmaker also treats heart disease. It is shown so the reader can see it, not because it implies anything on its own.
| Company | Paid to this provider | Part D cost of their drugs |
|---|---|---|
| Lilly USA, LLCMounjaro | $55 | $80,88361 claims |
| Novo NordiskOzempic | $513 | $20,60123 claims |
Reading this fairly. The Part D column is what drug plans and patients paid pharmacies — this provider received none of it, and it reflects how many patients they treat and what those drugs cost. Against peers, this provider's reported payments sit in the 95th percentile of 976 emergency medicine providers in Tennessee.
