Payments from drug & device makers
What this record shows
This record is dominated by royalties or licence payments: $483,499 of the $538,064 with a category attached, or 89.9%. Microport Orthopedics Inc accounts for 90.7% of it on its own, with 15 other manufacturers making up the rest. Reporting peaked in 2022 at $104,023 and has fallen 88.0% since, to $12,518 in 2025. Among adult reconstructive orthopaedic surgery clinicians in MO with any reported payments, this total sits in the top 10% — high for the specialty, which is a reason to read the composition above rather than the number alone.

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.
Most prescribed under Part D
| Drug | Claims | Cost to plans & patients |
|---|---|---|
| EliquisApixaban | 20 | $11,340 |
| Mupirocin | 158 | $934 |
| Amoxicillin | 68 | $104 |
| Clindamycin Hcl | 20 | $82 |
| Meloxicam | 41 | $68 |
