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. Tersera Therapeutics LLC accounts for 72.0% of it on its own, with 2 other manufacturers making up the rest. That places this record below the midpoint for anatomic pathology clinicians in TX, where the typical reported total is $109.
Across 3 payments — averaging $40.05 each. Meals, travel, consulting and speaking fees, gifts and royalties reported by drug and device makers.
- Tersera Therapeutics LLC$87
- Covidien LP$18

General payments by program year
Who reported the general payments

| Tersera Therapeutics LLC | 1 | $87 |
| Covidien LP | 1 | $18 |
| Stemline Therapeutics Inc. | 1 | $16 |
How this compares
$120 in reported general payments places this provider in the 50th percentile of 72 anatomic pathology 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.
