Payments from drug & device makers
What this record shows
Almost everything reported here is food and beverage — 100.0% of the total across 3 separate payments, which is the pattern of a clinician who attends manufacturer presentations rather than one with a consulting arrangement. Travere Therapeutics, Inc. accounts for 82.4% of it on its own, with 1 other manufacturer making up the rest. That places this record below the midpoint for nephrology clinicians in KS, where the typical reported total is $931.
Across 3 payments — averaging $37.14 each. Meals, travel, consulting and speaking fees, gifts and royalties reported by drug and device makers.
- Travere Therapeutics, Inc.$92
- Fresenius USA Marketing, Inc.$20
Across 126 payments — averaging $1455.42 each. Payments tied to a research study. These frequently flow through the physician to a hospital or research institution rather than to the physician personally.
- Travere Therapeutics, Inc.$183K
What the payments were for
- Food & beverage$111100%

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 |
|---|---|---|
| Travere Therapeutics, Inc. | 2 | $92 |
| Fresenius USA Marketing, Inc. | 1 | $20 |
How this compares
$111 in reported general payments places this provider in the 15th percentile of 55 nephrology providers in Kansas.
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.
Most prescribed under Part D
| Drug | Claims | Cost to plans & patients |
|---|---|---|
| Amlodipine Besylate | 17 | $109 |
| Furosemide | 12 | $68 |
| Prednisone | 12 | $66 |
| Lisinopril | 15 | $37 |
| Losartan Potassium | 17 | $17 |
