Payments from drug & device makers
What this record shows
The money is spread across several categories — food and beverage (53.8%), consulting fees and education — rather than concentrated in one kind of arrangement. 6 manufacturers reported payments, led by Dentsply LLC at 30.8% of the total. Reporting peaked in 2020 at $296 and has fallen 92.2% since, to $23 in 2024. That places this record below the midpoint for oral and maxillofacial surgery clinicians in CA, where the typical reported total is $639.
Across 13 payments — averaging $49.99 each. Meals, travel, consulting and speaking fees, gifts and royalties reported by drug and device makers.

- Dentsply Sirona Inc$196
- Ivoclar Vivadent, Inc.$155

What the payments were for

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.
| Company | Payments | Total |
|---|---|---|
| Dentsply LLC | 1 | $200 |
| Dentsply Sirona Inc | 7 | $196 |
| Ivoclar Vivadent, Inc. | 2 | $155 |
| Kuraray America Inc. | 1 | $60 |
| VOCO America Inc. | 1 | $21 |
| Keystone Dental Inc. | 1 | $18 |
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
$650 in reported general payments places this provider in the 50th percentile of 941 oral and maxillofacial surgery providers in California.

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 |
|---|---|---|
| Hydrocodone-AcetaminophenHydrocodone/Acetaminophen | 20 | $140 |
| Amoxicillin | 24 | $71 |
Paid to pharmacies, not to this prescriber.
