Payments from drug & device makers

What this record shows

The money is spread across several categories — speaking fees (59.5%), consulting fees and travel and lodging — rather than concentrated in one kind of arrangement. 18 manufacturers reported payments, led by Sanofi at 26.6% of the total. 2025 is the largest year on record at $239,707, more than ten times the $15 reported in 2020. Among internal medicine clinicians in CA 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.

Who reported the general payments

Companies are grouped under their corporate parent — a single manufacturer often files under several CMS reporting entities. Research and ownership payments are counted separately and are not in this table.

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

$347,147 in reported general payments places this provider in the 95th percentile of 13,581 internal medicine providers in California.

Medicare billing

Part B allowed, 2024
$125,630
Medicare patients
577
Services billed
1,829

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.
