How this compares

$33,881 in reported general payments places this provider in the 60th percentile of 157 hematology providers in New York.

Medicare billing

Part B allowed, 2024

$270,718

Medicare patients

827

Services billed

3,343

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.
