Payments from drug & device makers
What this record shows
Almost everything reported here is food and beverage — 99.7% of the total across 223 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 21.3% — the pattern of someone who eats at a lot of different presentations.
Across 223 payments — averaging $18.30 each. Meals, travel, consulting and speaking fees, gifts and royalties reported by drug and device makers.

- Organon$414
- Merck$377
- Myovant Sciences Inc.$254
- Hologic Sales And Service, LLC$246
- Astellas Pharma US Inc$198

Across 1 payment — averaging $17,134 each. Payments tied to a research study. These frequently flow through the physician to a hospital or research institution rather than to the physician personally.
- Genbiopro, Inc.$17K
What the payments were for
- Food & beverage$4,068100%
- Education$130%
Most of this is food and beverage — typically meals provided during product presentations at a clinic or hospital. Nationally that is the single largest category of reported payments by count.
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.
How this compares
$4,082 in reported general payments places this provider in the 85th 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 | 86 | $4,204 |
| Estradiol (Twice Weekly)Estradiol | 23 | $2,789 |
| ProgesteroneProgesterone, Micronized | 25 | $948 |
| ValacyclovirValacyclovir Hcl | 26 | $727 |
| Clobetasol Propionate | 20 | $365 |
| Medroxyprogesterone Acetate | 15 | $303 |
| Nystatin | 12 | $137 |
