What this record shows

Musculoskeletal Transplant Foundation Inc. accounts for 74.8% of it on its own, with 15 other manufacturers making up the rest. Reporting peaked in 2020 at $1,588 and has fallen 98.9% since, to $17 in 2025.
Across 33 payments — averaging $63.97 each. Meals, travel, consulting and speaking fees, gifts and royalties reported by drug and device makers.

How this compares
Too few trauma surgery providers in South Carolinato place this figure against a meaningful peer group, so we don't.
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.
