Payments from drug & device makers
What this record shows
Almost everything reported here is food and beverage — 100.0% of the total across 1 separate payments, which is the pattern of a clinician who attends manufacturer presentations rather than one with a consulting arrangement. Every reported general payment came from a single manufacturer, Otsuka America Pharmaceutical, Inc..
Across 1 payment — averaging $122.03 each. Meals, travel, consulting and speaking fees, gifts and royalties reported by drug and device makers.
- Otsuka America Pharmaceutical, Inc.$122
What the payments were for
- Food & beverage$122100%
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 |
|---|---|---|
| Otsuka America Pharmaceutical, 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.
- REXULTI$122
How this compares
Too few geriatric psychiatry providers in Virginiato place this figure against a meaningful peer group, so we don't.
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.
