Who reported the general payments

Medicare billing

Part B allowed, 2024

$29,439

Medicare patients

127

Services billed

132

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

Naproxen	21	$186
Omeprazole	17	$93
Ondansetron Hcl	21	$93

Paid to pharmacies, not to this prescriber.
