Payments from drug & device makers
What this record shows
Almost everything reported here is food and beverage — 100.0% of the total across 18 separate payments, which is the pattern of a clinician who attends manufacturer presentations rather than one with a consulting arrangement. 7 manufacturers reported payments, led by GE HealthCare at 29.6% of the total. Reporting peaked in 2019 at $834 and has fallen 75.1% since, to $208 in 2024. Among anesthesiology clinicians in CA with any reported payments, this total sits in the top 10% — high for the specialty, which is a reason to read the composition above rather than the number alone.
Across 18 payments — averaging $120.92 each. Meals, travel, consulting and speaking fees, gifts and royalties reported by drug and device makers.
- GE HealthCare$644
- Pajunk Medical Systems, LP$623
- Masimo Corporation$253
- Edwards Lifesciences$216
- Heron Therapeutics, Inc.$202
- Avanos Medical$124
- plus $114 from 1 others
Across 19 payments — averaging $11,437 each. Payments tied to a research study. These frequently flow through the physician to a hospital or research institution rather than to the physician personally.
- Pacira Pharmaceuticals Incorporated$217K
What the payments were for
- Food & beverage$2,177100%
Most of this is food and beverage — typically meals provided during product presentations at a clinic or hospital. Nationally that is the single largest category of reported payments by count.
General payments by program year
Who reported the general payments
Companies are grouped under their corporate parent — a single manufacturer often files under several CMS reporting entities. Research and ownership payments are counted separately and are not in this table.
| Company | Payments | Total |
|---|---|---|
| GE HealthCare | 5 | $644 |
| Pajunk Medical Systems, LP | 4 | $623 |
| Masimo Corporation | 2 | $253 |
| Edwards Lifesciences | 1 | $216 |
| Heron Therapeutics, Inc. | 3 | $202 |
| Avanos Medical | 2 | $124 |
| Pacira Pharmaceuticals Incorporated | 1 | $114 |
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.
- SedLine$167
- E-CATH PLUS ACC. TSUI$161
- IOVERA SYSTEM$114
How this compares
$2,177 in reported general payments places this provider in the 90th percentile of 5,717 anesthesiology 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.
