Payments from drug & device makers

What this record shows

This record is dominated by speaking fees: $21,675 of the $29,948 with a category attached, or 72.4%. Boston Scientific accounts for 85.8% of it on its own, with 11 other manufacturers making up the rest. Reporting peaked in 2020 at $15,733 and has fallen 98.5% since, to $241 in 2024. Among pain medicine clinicians in LA 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.

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
$54,503
Medicare patients
67
Services billed
307

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.
