Payments from drug & device makers
What this record shows
Almost everything reported here is food and beverage — 93.3% of the total across 66 separate payments, which is the pattern of a clinician who attends manufacturer presentations rather than one with a consulting arrangement. It is spread thinly across 27 manufacturers, the largest accounting for just 20.9% — the pattern of someone who eats at a lot of different presentations. Reporting peaked in 2019 at $1,102 and has fallen 92.7% since, to $80 in 2025.
Across 66 payments — averaging $48.74 each. Meals, travel, consulting and speaking fees, gifts and royalties reported by drug and device makers.

General payments by program year
Who reported the general payments

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
$3,217 in reported general payments places this provider in the 75th percentile of 627 radiation oncology 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 |
|---|---|---|
| Tamsulosin Hcl | 100 | $670 |
| Hydrocodone-AcetaminophenHydrocodone/Acetaminophen | 12 | $52 |
Paid to pharmacies, not to this prescriber.
