Payments from drug & device makers
What this record shows
This record is dominated by food and beverage: $377 of the $502 with a category attached, or 75.1%. 8 manufacturers reported payments, led by Sumitomo Pharma America, Inc. at 30.9% of the total. 2025 is the largest year on record at $308, more than ten times the $15 reported in 2023. Among emergency medicine 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 11 payments — averaging $45.61 each. Meals, travel, consulting and speaking fees, gifts and royalties reported by drug and device makers.
- Sumitomo Pharma America, Inc.$155
- Johnson & Johnson$144
- Bayer$76
- Axsome Therapeutics, Inc.$33
- Azurity Pharmaceuticals, Inc.$30
- Cycle Pharmaceuticals Inc$28
- plus $37 from 2 others
What the payments were for
- Speaking & faculty fees$12525%
- Food & beverage$37775%
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 |
|---|---|---|
| Sumitomo Pharma America, Inc. | 2 | $155 |
| Johnson & Johnson | 1 | $144 |
| Bayer | 3 | $76 |
| Axsome Therapeutics, Inc. | 1 | $33 |
| Azurity Pharmaceuticals, Inc. | 1 | $30 |
| Cycle Pharmaceuticals Inc | 1 | $28 |
| Noven Therapeutics, LLC | 1 | $21 |
| Lilly USA, LLC | 1 | $15 |
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
$502 in reported general payments places this provider in the 90th percentile of 6,006 emergency medicine 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 |
|---|---|---|
| Sucralfate | 12 | $382 |
| Amoxicillin-Clavulanate PotassAmoxicillin/Potassium Clav | 21 | $295 |
| Albuterol Sulfate HfaAlbuterol Sulfate | 11 | $208 |
| Ondansetron OdtOndansetron | 23 | $179 |
