Payments from drug & device makers
What this record shows
This record is dominated by food and beverage: $1,958 of the $2,206 with a category attached, or 88.7%. It is spread thinly across 9 manufacturers, the largest accounting for just 20.7% — the pattern of someone who eats at a lot of different presentations. 2025 is the largest year on record at $1,109, more than ten times the $77 reported in 2021.
Across 27 payments — averaging $81.72 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
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 |
|---|---|---|
| Pulmonx Corporation | 5 | $457 |
| Intuitive Surgical | 7 | $402 |
| Pinnacle Biologics, Inc | 3 | $307 |
| Sanofi | 4 | $285 |
| Astellas Pharma US Inc | 3 | $249 |
| Penumbra, Inc. | 1 | $163 |
| Galvanize Therapeutics, Inc | 1 | $136 |
| ERBE USA Inc | 1 | $108 |
| Johnson & Johnson | 2 | $99 |
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
$2,206 in reported general payments places this provider in the 55th percentile of 1,261 pulmonary disease 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 |
|---|---|---|
| Albuterol Sulfate HfaAlbuterol Sulfate | 16 | $414 |
| Amoxicillin-Clavulanate PotassAmoxicillin/Potassium Clav | 15 | $69 |
| Azithromycin | 11 | $39 |
