Payments from drug & device makers
What this record shows
This record is dominated by food and beverage: $3,940 of the $5,252 with a category attached, or 75.0%. It is spread thinly across 44 manufacturers, the largest accounting for just 11.4% — the pattern of someone who eats at a lot of different presentations. Reporting peaked in 2024 at $2,670 and has fallen 54.2% since, to $1,221 in 2025. Among nurse practitioner clinicians in CT 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 202 payments — averaging $26.00 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.
How this compares
$5,252 in reported general payments places this provider in the 95th percentile of 1,162 nurse practitioner providers in Connecticut.
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 |
|---|---|---|
| Dexamethasone | 12 | $498 |
| Oxycodone-AcetaminophenOxycodone Hcl/Acetaminophen | 16 | $133 |
