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.

Novartis	3	$4,048
Eisai Inc.	1	$125
AstraZeneca	1	$96
Welch Allyn	1	$82
EMD Serono, Inc.	1	$13

Medicare billing

Part B allowed, 2024

$199,656

Medicare patients

475

Services billed

1,586

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.
