Payments from drug & device makers
What this record shows
The money is spread across several categories — food and beverage (38.8%), travel and lodging and speaking fees — rather than concentrated in one kind of arrangement. 10 manufacturers reported payments, led by Microport Orthopedics Inc at 30.5% of the total. 2025 is the largest year on record at $2,494, 2.2 times the $1,152 reported in 2019. That places this record below the midpoint for orthopaedic trauma clinicians in CA, where the typical reported total is $9,676.
Across 43 payments — averaging $153.59 each. Meals, travel, consulting and speaking fees, gifts and royalties reported by drug and device makers.

What the payments were tied to
Products named in the reported payments. Only payments of $100 or more are attributed here — the typical reported payment nationally is a meal worth about $16, and listing those product-by-product would be noise.

How this compares
$6,604 in reported general payments places this provider in the 40th percentile of 106 orthopaedic trauma providers in California.
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 |
|---|---|---|
| Celecoxib | 266 | $5,711 |
| Diclofenac Sodium | 57 | $804 |
| Hydrocodone-AcetaminophenHydrocodone/Acetaminophen | 37 | $223 |
| Oxycodone-AcetaminophenOxycodone Hcl/Acetaminophen | 23 | $173 |
