Payments from drug & device makers
What this record shows
Almost everything reported here is food and beverage — 100.0% of the total across 299 separate payments, which is the pattern of a clinician who attends manufacturer presentations rather than one with a consulting arrangement. It is spread thinly across 27 manufacturers, the largest accounting for just 14.9% — the pattern of someone who eats at a lot of different presentations. Among child & adolescent psychiatry clinicians in AZ with any reported payments, this total sits in the top 10% — high for the specialty, which is a reason to read the composition above rather than the number alone.
Across 299 payments — averaging $21.99 each. Meals, travel, consulting and speaking fees, gifts and royalties reported by drug and device makers.

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 |
|---|---|---|
| Almatica Pharma LLCSertraline Hcl | $23 | $58055 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 90th percentile of 80 child & adolescent psychiatry providers in Arizona.
