Who reported the general payments

Medicare billing

Part B allowed, 2024

$1,650,137

Medicare patients

2,390

Services billed

9,681

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

Drug	Claims	Cost to plans & patients
Celecoxib	28	$697
Amoxicillin	76	$193
Oxycodone-AcetaminophenOxycodone Hcl/Acetaminophen	12	$181
