Payments from drug & device makers
What this record shows
The money is spread across several categories — travel and lodging (35.3%), food and beverage and consulting fees — rather than concentrated in one kind of arrangement. 20 manufacturers reported payments, led by Abbott at 37.3% of the total. Among gerontology clinicians in AZ 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 101 payments — averaging $110.47 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

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 |
|---|---|---|
| Acadia Pharmaceuticals IncNuplazid | $984 | $75,02815 claims |
| Amneal Pharmaceuticals LLCRytary | $713 | $27,29212 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 99 gerontology providers in Arizona.
