Payments from drug & device makers
What this record shows
The money is spread across several categories — speaking fees (36.4%), food and beverage and consulting fees — rather than concentrated in one kind of arrangement. Reflexion Medical, Inc. accounts for 63.2% of it on its own, with 12 other manufacturers making up the rest. Reporting peaked in 2022 at $11,508 and has fallen 97.4% since, to $304 in 2025. Among radiation oncology clinicians in PA with any reported payments, this total sits in the top 10% — high for the specialty, which is a reason to read the composition above rather than the number alone.
Across 48 payments — averaging $360.34 each. Meals, travel, consulting and speaking fees, gifts and royalties reported by drug and device makers.

General payments by program year

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.

- ELEKTA MEDICAL LINEAR ACCELERATOR$696
- Clarity$174
How this compares
$17,296 in reported general payments places this provider in the 90th percentile of 339 radiation oncology providers in Pennsylvania.
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 |
|---|---|---|
| Tamsulosin Hcl | 37 | $417 |
| Oxycodone Hcl | 18 | $344 |
