Payments from drug & device makers
What this record shows
This record is dominated by food and beverage: $7,523 of the $8,665 with a category attached, or 86.8%. It is spread thinly across 55 manufacturers, the largest accounting for just 16.4% — the pattern of someone who eats at a lot of different presentations. Reporting peaked in 2022 at $2,526 and has fallen 82.2% since, to $449 in 2025. Among nurse practitioner clinicians in TX with any reported payments, this total sits in the top 5% — high for the specialty, which is a reason to read the composition above rather than the number alone.
Across 276 payments — averaging $31.40 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.
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.
- NURTEC ODT$1,216
- KRYSTEXXA$348
- JYNARQUE$228
- FREESTYLE LIBRE 3$153
- Veltassa$125
- UBRELVY$122
- Kerendia$122

- Prolastin-C Liquid$116
- AMVUTTRA$108
- CRYSVITA$107

How this compares
$8,665 in reported general payments places this provider in the 95th percentile of 5,422 nurse practitioner providers in Texas.
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.
