Payments from drug & device makers
What this record shows
This record is dominated by speaking fees: $121,628 of the $180,213 with a category attached, or 67.5%. Gilead accounts for 66.2% of it on its own, with 12 other manufacturers making up the rest. 2025 is the largest year on record at $70,678, 9.8 times the $7,189 reported in 2021. Among adult health clinicians in MD 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.
Across 642 payments — averaging $280.71 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.

| Viiv Healthcare Company | 199 | $57,252 |

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.

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.
| Company | Paid to this provider | Part D cost of their drugs |
|---|---|---|
| GileadBiktarvy, Descovy | $119,221 | $1,751,911446 claims |
| Viiv Healthcare CompanyJuluca, Tivicay | $57,252 | $445,686142 claims |
| MerckPifeltro | $1,924 | $49,23028 claims |
| Johnson & JohnsonPrezcobix | $135 | $32,45014 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 542 adult health providers in Maryland.
