Payments from drug & device makers
What this record shows
This record is dominated by food and beverage: $3,933 of the $4,453 with a category attached, or 88.3%. 8 manufacturers reported payments, led by Avanir Pharmaceuticals, Inc. at 40.9% of the total. Reporting peaked in 2022 at $1,700 and has fallen 81.8% since, to $309 in 2025. Among gerontology clinicians in MO 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 195 payments — averaging $22.83 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 |
|---|---|---|
| Avanir Pharmaceuticals, Inc. | 83 | $1,823 |
| Otsuka America Pharmaceutical, Inc. | 61 | $1,176 |
| Acadia Pharmaceuticals Inc | 10 | $677 |
| Neurocrine Biosciences, Inc. | 26 | $486 |
| UCB, Inc. | 5 | $128 |
| Sumitomo Pharma America, Inc. | 5 | $82 |
| Urovant Sciences Inc | 4 | $64 |
| Sunovion Pharmaceuticals Inc. | 1 | $16 |
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
$4,453 in reported general payments places this provider in the 90th percentile of 175 gerontology providers in Missouri.
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.
