Payments from drug & device makers
Across 2 payments — averaging $123.42 each. Meals, travel, consulting and speaking fees, gifts and royalties reported by drug and device makers.
- Vanda Pharmaceuticals Inc.$125
- Teva Pharmaceuticals USA, Inc.$122
What the payments were for
- Food & beverage$247100%
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.
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 |
|---|---|---|
| Vanda Pharmaceuticals Inc. | 1 | $125 |
| Teva Pharmaceuticals USA, Inc. | 1 | $122 |
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.
- Fanapt$125
- Austedo XR$122
How this compares
$247 in reported general payments places this provider in the 45th percentile of 348 gerontology 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

| OxycontinOxycodone Hcl | 18 | $5,043 |
| Hydrocodone-AcetaminophenHydrocodone/Acetaminophen | 47 | $513 |
| Hydromorphone Hcl | 42 | $417 |
