Payments from drug & device makers

What this record shows

Almost everything reported here is food and beverage — 100.0% of the total across 39 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 15 manufacturers, the largest accounting for just 21.1% — the pattern of someone who eats at a lot of different presentations.

Medicare billing

Part B allowed, 2024
$562,576
Medicare patients
1,881
Services billed
5,104

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
AbbVieRestasis, Lumigan, Alphagan P$47$89,89073 claims
Bausch & Lomb Americas Inc.Xiidra, Zirgan$42$48,94955 claims
Oyster Point Pharma, Inc.Tyrvaya$52$13,19118 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 55th percentile of 35 cornea and external diseases specialist providers in Texas.
