Payments from drug & device makers
What this record shows
Almost everything reported here is food and beverage — 100.0% of the total across 11 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 9 manufacturers, the largest accounting for just 19.7% — the pattern of someone who eats at a lot of different presentations. That places this record below the midpoint for family medicine clinicians in TX, where the typical reported total is $436.
Across 11 payments — averaging $22.08 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 |
|---|---|---|
| Dexcom, Inc. | 2 | $48 |
| Lilly USA, LLC | 2 | $47 |
| Novo Nordisk | 1 | $30 |
| Pfizer | 1 | $24 |
| Abbott | 1 | $22 |

How this compares
$243 in reported general payments places this provider in the 40th percentile of 8,760 family medicine 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.
Most prescribed under Part D
| Drug | Claims | Cost to plans & patients |
|---|---|---|
| Etodolac | 24 | $338 |
| Nitrofurantoin Mono-MacroNitrofurantoin Monohyd/M-Cryst | 18 | $255 |
| Doxycycline Hyclate | 22 | $205 |
| Azithromycin | 44 | $146 |
| Amoxicillin | 21 | $78 |
