Payments from drug & device makers
What this record shows
This record is dominated by speaking fees: $2,850 of the $4,025 with a category attached, or 70.8%. AbbVie accounts for 73.6% of it on its own, with 12 other manufacturers making up the rest. 2025 is the largest year on record at $3,054, more than ten times the $38 reported in 2019. That places this record below the midpoint for hematology & oncology clinicians in CA, where the typical reported total is $3,371.
Across 23 payments — averaging $175.00 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
$4,025 in reported general payments places this provider in the 50th percentile of 1,363 hematology & 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.
