Payments from drug & device makers
What this record shows
This record is dominated by consulting fees: $219,373 of the $220,478 with a category attached, or 99.5%. Exthera Medical Corporation accounts for 99.5% of it on its own, with 7 other manufacturers making up the rest. 2025 is the largest year on record at $136,974, more than ten times the $581 reported in 2019.

Medicare billing
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.
