Payments from drug & device makers

What this record shows

This record is dominated by speaking fees: $76,850 of the $99,935 with a category attached, or 76.9%. Viiv Healthcare Company accounts for 66.9% of it on its own, with 18 other manufacturers making up the rest. Reporting peaked in 2019 at $59,791 and has fallen 99.9% since, to $54 in 2025. Among infectious disease 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.

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.

How this compares

$99,935 in reported general payments places this provider in the 95th percentile of 576 infectious disease providers in Texas.

Medicare billing

Part B allowed, 2024
$18,796
Medicare patients
27
Services billed
147

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.

Paid to pharmacies, not to this prescriber.

Companies that both paid and supply prescribed drugs

These companies both reported payments to this provider and make drugs the provider prescribed under Medicare Part D in 2024. For most specialties this overlap is expected — a cardiologist who is paid by a cardiology drugmaker also treats heart disease. It is shown so the reader can see it, not because it implies anything on its own.

CompanyPaid to this providerPart D cost of their drugs
Viiv Healthcare CompanyDovato, Juluca, Tivicay$66,808$357,361103 claims
GileadBiktarvy$5,774$101,95324 claims
Johnson & JohnsonPrezcobix$539$34,41014 claims

Reading this fairly. The Part D column is what drug plans and patients paid pharmacies — this provider received none of it, and it reflects how many patients they treat and what those drugs cost. Against peers, this provider's reported payments sit in the 95th percentile of 576 infectious disease providers in Texas.
