Payments from drug & device makers
What this record shows
Almost everything reported here is food and beverage — 97.7% of the total across 53 separate payments, which is the pattern of a clinician who attends manufacturer presentations rather than one with a consulting arrangement. 12 manufacturers reported payments, led by Kerecis Limited at 25.5% of the total. Reporting peaked in 2024 at $1,050 and has fallen 59.7% since, to $424 in 2025.
Across 53 payments — averaging $50.81 each. Meals, travel, consulting and speaking fees, gifts and royalties reported by drug and device makers.

General payments by program year

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
$2,693 in reported general payments places this provider in the 75th percentile of 151 podiatrist 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 |
|---|---|---|
| Ammonium Lactate | 37 | $851 |
| Ciclopirox | 18 | $619 |
| Doxycycline Monohydrate | 12 | $239 |
| Terbinafine Hcl | 28 | $197 |
| Amoxicillin-Clavulanate PotassAmoxicillin/Potassium Clav | 14 | $171 |
| Methylprednisolone | 11 | $58 |
