Genentech USA, Inc. accounts for 79.8% of it on its own, with 16 other manufacturers making up the rest. 2025 is the largest year on record at $22,101, more than ten times the $744 reported in 2019.

Medicare billing

Part B allowed, 2024

$1,789,308

Medicare patients

768

Services billed

28,293

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
