Payments from drug & device makers
What this record shows
This record is dominated by speaking fees: $261,100 of the $264,477 with a category attached, or 98.7%. Hiossen, Inc. accounts for 94.9% of it on its own, with 7 other manufacturers making up the rest. Reporting peaked in 2019 at $63,160 and has fallen 67.0% since, to $20,863 in 2025. Among periodontics clinicians in CA 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.

How this compares
$264,477 in reported general payments places this provider in the 95th percentile of 716 periodontics 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 |
|---|---|---|
| Chlorhexidine Gluconate | 113 | $727 |
| Amoxicillin | 130 | $454 |
| Ibuprofen | 108 | $342 |
| Methylprednisolone | 11 | $70 |
| Azithromycin | 12 | $46 |
