Payments from drug & device makers
What this record shows
This record is dominated by other: $2,274,810 of the $2,415,709 with a category attached, or 94.2%. Stryker accounts for 94.2% of it on its own, with 24 other manufacturers making up the rest. 2025 is the largest year on record at $2,296,585, more than ten times the $46,542 reported in 2019. Among colon & rectal surgery clinicians in CA with any reported payments, this total sits in the top 5% — high for the specialty, which is a reason to read the composition above rather than the number alone.
Across 198 payments — averaging $12,201 each. Meals, travel, consulting and speaking fees, gifts and royalties reported by drug and device makers.

How this compares
$2,415,709 in reported general payments places this provider in the 95th percentile of 176 colon & rectal surgery 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 |
|---|---|---|
| Neomycin Sulfate | 16 | $73 |
| Metronidazole | 17 | $16 |
Paid to pharmacies, not to this prescriber.
