Payments from drug & device makers
What this record shows
Almost everything reported here is food and beverage — 100.0% of the total across 15 separate payments, which is the pattern of a clinician who attends manufacturer presentations rather than one with a consulting arrangement. It is spread thinly across 9 manufacturers, the largest accounting for just 21.8% — the pattern of someone who eats at a lot of different presentations. 2025 is the largest year on record at $135, 4.4 times the $31 reported in 2022. That places this record below the midpoint for radiation oncology clinicians in PA, where the typical reported total is $405.
Across 15 payments — averaging $21.41 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.
| Company | Payments | Total |
|---|---|---|
| Novartis | 3 | $70 |
| Incyte Corporation | 2 | $43 |
| Myriad Genetic Laboratories, Inc. | 3 | $43 |
| Boston Scientific | 2 | $40 |
| Novocure Inc. | 1 | $34 |
| Regeneron Healthcare Solutions, Inc. | 1 | $27 |
| Bioprotect Medical, Inc. | 1 | $25 |
| AstraZeneca | 1 | $21 |

How this compares
$321 in reported general payments places this provider in the 40th 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 | 25 | $269 |
| Lidocaine Hcl ViscousLidocaine Hcl | 15 | $236 |
| Oxycodone Hcl | 11 | $57 |
