Payments from drug & device makers
What this record shows
Almost everything reported here is food and beverage — 100.0% of the total across 28 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 14 manufacturers, the largest accounting for just 17.6% — the pattern of someone who eats at a lot of different presentations. 2025 is the largest year on record at $240, more than ten times the $12 reported in 2019. That places this record below the midpoint for mohs-micrographic surgery clinicians in AZ, where the typical reported total is $1,522.
Across 28 payments — averaging $21.64 each. Meals, travel, consulting and speaking fees, gifts and royalties reported by drug and device makers.

How this compares
$606 in reported general payments places this provider in the 20th percentile of 38 mohs-micrographic surgery 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 |

Paid to pharmacies, not to this prescriber.
