Payments from drug & device makers
What this record shows
Almost everything reported here is food and beverage — 100.0% of the total across 68 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 28 manufacturers, the largest accounting for just 13.6% — the pattern of someone who eats at a lot of different presentations.
Across 68 payments — averaging $22.76 each. Meals, travel, consulting and speaking fees, gifts and royalties reported by drug and device makers.
- Amgen$211
- Bayer$139
- Vertex$128
- AbbVie$127
- Urovant Sciences Inc$114
- Myovant Sciences Inc.$76
- plus $753 from 22 others
Across 1 payment — averaging $8000.00 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.

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
$1,547 in reported general payments places this provider in the 60th percentile of 318 obstetrics & gynecology providers in Mississippi.
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 | 40 | $1,752 |
| Fluconazole | 26 | $157 |
| Zolpidem Tartrate | 11 | $22 |
Paid to pharmacies, not to this prescriber.
