Payments from drug & device makers
What this record shows
The money is spread across several categories — travel and lodging (57.1%), food and beverage and consulting fees — rather than concentrated in one kind of arrangement. 24 manufacturers reported payments, led by Innovasis Inc at 27.0% of the total. Reporting peaked in 2023 at $4,810 and has fallen 88.1% since, to $571 in 2025. That places this record below the midpoint for orthopaedic surgery of the spine clinicians in CA, where the typical reported total is $17,657.
Across 130 payments — averaging $135.82 each. Meals, travel, consulting and speaking fees, gifts and royalties reported by drug and device makers.

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 |
|---|---|---|
| Hydrocodone-AcetaminophenHydrocodone/Acetaminophen | 35 | $309 |
| Ibuprofen | 28 | $254 |
| Gabapentin | 12 | $82 |
