Medicare billing

Part B allowed, 2024

$6,340

Medicare patients

Services billed

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
Lurasidone Hcl	13	$4,256
Lisdexamfetamine Dimesylate	13	$2,333
Duloxetine Hcl	18	$794
Dextroamphetamine-Amphet ErDextroamphetamine/Amphetamine	11	$609
Fluoxetine Hcl	16	$590
