Payments from drug & device makers
What this record shows
Almost everything reported here is food and beverage — 100.0% of the total across 10 separate payments, which is the pattern of a clinician who attends manufacturer presentations rather than one with a consulting arrangement. 5 manufacturers reported payments, led by United Therapeutics Corporation at 34.1% of the total. Reporting peaked in 2019 at $63 and has fallen 64.6% since, to $22 in 2025. That places this record below the midpoint for infectious disease clinicians in AR, where the typical reported total is $411.
Across 10 payments — averaging $18.33 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 |
|---|---|---|
| United Therapeutics Corporation | 3 | $63 |
| AbbVie | 3 | $52 |
| Jazz Pharmaceuticals Inc. | 2 | $26 |
| ITI, Inc. (d/b/a Intra-cellular Therapies, Inc.) | 1 | $22 |
| Merck | 1 | $20 |
How this compares
$183 in reported general payments places this provider in the 40th percentile of 36 infectious disease providers in Arkansas.
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.
