Payments from drug & device makers
What this record shows
The money is spread across several categories — consulting fees (58.2%), travel and lodging and food and beverage — rather than concentrated in one kind of arrangement. Pfizer accounts for 97.1% of it on its own, with 4 other manufacturers making up the rest. Reporting peaked in 2020 at $4,550 and has fallen 98.6% since, to $64 in 2025. Among obstetrics & gynecology 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 15 payments — averaging $521.07 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.
