Reporting peaked in 2022 at $301 and has fallen 58.5% since, to $125 in 2025.

Medicare billing

Part B allowed, 2024

$37,489

Medicare patients

185

Services billed

335

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.
