Payments from drug & device makers
What this record shows
Almost everything reported here is food and beverage — 100.0% of the total across 23 separate payments, which is the pattern of a clinician who attends manufacturer presentations rather than one with a consulting arrangement. It is spread thinly across 12 manufacturers, the largest accounting for just 20.6% — the pattern of someone who eats at a lot of different presentations. Reporting peaked in 2019 at $311 and has fallen 86.3% since, to $43 in 2025. That places this record below the midpoint for pain medicine clinicians in OK, where the typical reported total is $1,721.
Across 23 payments — averaging $30.87 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 |
|---|---|---|
| Nevro Corp. | 2 | $146 |
| Relievant Medsystems, Inc. | 6 | $118 |
| Boston Scientific | 1 | $107 |
| Salix Pharmaceuticals, A Division Of Bausch Health US, LLC | 1 | $100 |
| Stryker | 2 | $44 |
| Vertex | 2 | $43 |
| Si-bone, Inc. | 2 | $40 |
| Polynovo North America LLC | 1 | $37 |
| Biodelivery Sciences International, Inc. | 3 | $36 |
| Abbott | 1 | $17 |
| Pfizer | 1 | $11 |
| Pylant Medical | 1 | $11 |
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
$710 in reported general payments places this provider in the 35th percentile of 68 pain medicine providers in Oklahoma.
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.
