Payments from drug & device makers
What this record shows
This record is dominated by food and beverage: $108 of the $146 with a category attached, or 74.0%. 3 manufacturers reported payments, led by Viiv Healthcare Company at 56.7% of the total. That places this record below the midpoint for infectious disease clinicians in DC, where the typical reported total is $240.
Across 7 payments — averaging $20.85 each. Meals, travel, consulting and speaking fees, gifts and royalties reported by drug and device makers.
- Viiv Healthcare Company$83
- Merck$38
- Gilead$25
Across 73 payments — averaging $3960.07 each. Payments tied to a research study. These frequently flow through the physician to a hospital or research institution rather than to the physician personally.
- Novartis$146K
- Gilead$143K
What the payments were for
- Food & beverage$10874%
- Education$3826%
Most of this is food and beverage — typically meals provided during product presentations at a clinic or hospital. Nationally that is the single largest category of reported payments by count.

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.

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, Genvoya, Descovy | $25 | $1,331,686322 claims |
| Viiv Healthcare CompanyDovato, Tivicay, Triumeq, Juluca | $83 | $721,896243 claims |
| MerckIsentress | $38 | $31,13816 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 35th percentile of 74 infectious disease providers in District of Columbia.
