Payments from drug & device makers
What this record shows
This record is dominated by food and beverage: $378 of the $421 with a category attached, or 89.9%. It is spread thinly across 15 manufacturers, the largest accounting for just 15.9% — the pattern of someone who eats at a lot of different presentations. Reporting peaked in 2019 at $224 and has fallen 97.6% since, to $5 in 2025. That places this record below the midpoint for obstetrics & gynecology clinicians in AZ, where the typical reported total is $619.
Across 29 payments — averaging $14.50 each. Meals, travel, consulting and speaking fees, gifts and royalties reported by drug and device makers.

How this compares
$421 in reported general payments places this provider in the 40th percentile of 757 obstetrics & gynecology providers in Arizona.
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 |
|---|---|---|
| Estradiol | 29 | $531 |
| Clobetasol Propionate | 18 | $453 |
| ProgesteroneProgesterone, Micronized | 19 | $409 |
| Medroxyprogesterone Acetate | 18 | $238 |
| Misoprostol | 18 | $38 |
