Payments from drug & device makers
What this record shows
The money is spread across several categories — speaking fees (49.2%), travel and lodging and food and beverage — rather than concentrated in one kind of arrangement. Medtronic accounts for 81.5% of it on its own, with 26 other manufacturers making up the rest. Reporting peaked in 2019 at $100,422 and has fallen 95.6% since, to $4,379 in 2025. Among clinical cardiac electrophysiology clinicians in TN 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 980 payments — averaging $137.00 each. Meals, travel, consulting and speaking fees, gifts and royalties reported by drug and device makers.

General payments by program year

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.

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.

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 |
|---|---|---|
| PfizerEliquis | $678 | $620,604635 claims |
| Johnson & JohnsonXarelto | $196 | $199,624171 claims |
| NovartisEntresto | $1,476 | $158,715152 claims |
| Boehringer IngelheimJardiance, Pradaxa | $381 | $137,670149 claims |
| AstraZenecaFarxiga | $312 | $76,76385 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 90th percentile of 82 clinical cardiac electrophysiology providers in Tennessee.
