Payments from drug & device makers
What this record shows

Livanova USA, Inc. accounts for 74.3% of it on its own, with 3 other manufacturers making up the rest. Reporting peaked in 2019 at $2,486 and has fallen 93.7% since, to $158 in 2025.
Across 37 payments — averaging $183.08 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 |
|---|---|---|
| Livanova USA, Inc. | 26 | $5,030 |
| Medtronic(2 entities) | 8 | $1,456 |
| Neuropace, Inc. | 2 | $182 |
| UCB, Inc. | 1 | $105 |
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.
- VNS Therapy$4,022
- ACTIVA$1,030
- PERCEPT PC BRAINSENSE$150
- VNS THERAPY SENTIVA MODEL 1000 GENERATOR$136
- RNS Neurostimulator Kit$125

How this compares
$6,774 in reported general payments places this provider in the 70th percentile of 474 neurology providers in Virginia.
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.
