Payments from drug & device makers
What this record shows
The money is spread across several categories — food and beverage (54.5%), travel and lodging and education — rather than concentrated in one kind of arrangement. Pfizer accounts for 73.4% of it on its own, with 15 other manufacturers making up the rest. Reporting peaked in 2019 at $1,899 and has fallen 89.0% since, to $209 in 2025.
Across 40 payments — averaging $59.46 each. Meals, travel, consulting and speaking fees, gifts and royalties reported by drug and device makers.
- Pfizer$2K
- Meditrina$122
- AbbVie$107
- Bayer$61
- Avion Pharmaceuticals$48
- Hologic Sales And Service, LLC$47
- plus $246 from 10 others
Across 291 payments — averaging $5021.65 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.

How this compares
$2,378 in reported general payments places this provider in the 80th percentile of 992 obstetrics & gynecology providers in Virginia.
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.
Most prescribed under Part D
| Drug | Claims | Cost to plans & patients |
|---|---|---|
| Medroxyprogesterone Acetate | 14 | $204 |
| Metronidazole | 14 | $80 |
