Payments from drug & device makers
What this record shows
The money is spread across several categories — speaking fees (48.8%), food and beverage and travel and lodging — rather than concentrated in one kind of arrangement. Boston Scientific accounts for 69.4% of it on its own, with 15 other manufacturers making up the rest. Reporting peaked in 2022 at $12,277 and has fallen 88.9% since, to $1,362 in 2025. That places this record below the midpoint for clinical cardiac electrophysiology clinicians in AZ, where the typical reported total is $29,180.
Across 323 payments — averaging $74.59 each. Meals, travel, consulting and speaking fees, gifts and royalties reported by drug and device makers.

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 |
|---|---|---|
| EliquisApixaban | 15 | $11,425 |
| Doxycycline Hyclate | 17 | $213 |
Paid to pharmacies, not to this prescriber.
