Payments from drug & device makers

What this record shows

Almost everything reported here is food and beverage — 100.0% of the total across 114 separate payments, which is the pattern of a clinician who attends manufacturer presentations rather than one with a consulting arrangement. Abbott accounts for 88.1% of it on its own, with 2 other manufacturers making up the rest. That places this record below the midpoint for pain medicine clinicians in NV, where the typical reported total is $2,557.

General payments by program year

Who reported the general payments

Boston Scientific	2	$73

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

Part B allowed, 2024

$105,705

Medicare patients

239

Services billed

1,059

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.
