Payments from drug & device makers
What this record shows
This record is dominated by speaking fees: $29,929 of the $30,983 with a category attached, or 96.6%. Patterson Companies, Inc. accounts for 89.4% of it on its own, with 6 other manufacturers making up the rest. Reporting peaked in 2022 at $10,824 and has fallen 99.0% since, to $106 in 2025. Among general practice clinicians in AZ with any reported payments, this total sits in the top 5% — high for the specialty, which is a reason to read the composition above rather than the number alone.
Across 37 payments — averaging $837.39 each. Meals, travel, consulting and speaking fees, gifts and royalties reported by drug and device makers.

General payments by program year
Who reported the general payments
Companies are grouped under their corporate parent — a single manufacturer often files under several CMS reporting entities. Research and ownership payments are counted separately and are not in this table.

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.
- CEREC CAD/CAM$10,000
- CEREC$9,050
- PLANMECA PROMAX$2,250
- Orthophos E$125
How this compares
$30,983 in reported general payments places this provider in the 95th percentile of 1,998 general practice 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 |
|---|---|---|
| Amoxicillin | 27 | $77 |
| Azithromycin | 11 | $72 |
| Methylprednisolone | 11 | $59 |
Paid to pharmacies, not to this prescriber.
