Payments from drug & device makers
What this record shows
The money is spread across several categories — food and beverage (48.3%), speaking fees and consulting fees — rather than concentrated in one kind of arrangement. 18 manufacturers reported payments, led by Jazz Pharmaceuticals Inc. at 57.8% of the total. 2025 is the largest year on record at $9,385, more than ten times the $611 reported in 2019. Among sleep 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 457 payments — averaging $43.20 each. Meals, travel, consulting and speaking fees, gifts and royalties reported by drug and device makers.

General payments by program year
Who reported the general payments

How this compares
$19,741 in reported general payments places this provider in the 95th percentile of 41 sleep medicine providers in Tennessee.
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
