Medicare billing

Part B allowed, 2024

$85,835

Medicare patients

135

Services billed

336

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
Oxycodone Hcl	61	$233
Cyclobenzaprine Hcl	46	$165
Baclofen	12	$157
