Payments from drug & device makers
What this record shows
Almost everything reported here is food and beverage — 100.0% of the total across 8 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 8 manufacturers, the largest accounting for just 15.3% — the pattern of someone who eats at a lot of different presentations. 2025 is the largest year on record at $69, 3.4 times the $20 reported in 2021. That places this record below the midpoint for internal medicine clinicians in TX, where the typical reported total is $270.
Across 8 payments — averaging $18.67 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 |
|---|---|---|
| Otsuka America Pharmaceutical, Inc. | 1 | $23 |
| Dexcom, Inc. | 1 | $22 |
| Amgen | 1 | $22 |
| Bayer | 1 | $20 |
| Sumitomo Pharma America, Inc. | 1 | $19 |
| Lilly USA, LLC | 1 | $15 |

How this compares
$149 in reported general payments places this provider in the 35th percentile of 7,675 internal 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.
