Payments from drug & device makers
What this record shows
This record is dominated by speaking fees: $1,648,530 of the $1,648,581 with a category attached, or 100.0%. Vanda Pharmaceuticals Inc. accounts for 100.0% of it on its own, with 1 other manufacturer making up the rest. Among rheumatology clinicians in DC 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 35 payments — averaging $47,102 each. Meals, travel, consulting and speaking fees, gifts and royalties reported by drug and device makers.

How this compares
$1,648,581 in reported general payments places this provider in the 95th percentile of 41 rheumatology providers in District of Columbia.
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

| Humira PenAdalimumab | 14 | $97,713 |
| Enbrel SureclickEtanercept | 12 | $87,195 |
