Payments from drug & device makers

What this record shows

Almost everything reported here is food and beverage — 93.1% of the total across 264 separate payments, which is the pattern of a clinician who attends manufacturer presentations rather than one with a consulting arrangement. It is spread thinly across 38 manufacturers, the largest accounting for just 11.8% — the pattern of someone who eats at a lot of different presentations. Reporting peaked in 2020 at $1,251 and has fallen 57.6% since, to $530 in 2024.

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

$4,691 in reported general payments places this provider in the 55th percentile of 361 neurology providers in Tennessee.

Medicare billing

Part B allowed, 2024
$156,305
Medicare patients
638
Services billed
1,117

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.
