Payments from drug & device makers
What this record shows
The money is spread across several categories — speaking fees (51.6%), food and beverage and consulting fees — rather than concentrated in one kind of arrangement. Novocure Inc. accounts for 86.0% of it on its own, with 26 other manufacturers making up the rest. Among radiation oncology clinicians in MO 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 148 payments — averaging $276.89 each. Meals, travel, consulting and speaking fees, gifts and royalties reported by drug and device makers.
- Novocure Inc.$35K
- GT Medical Technologies, Inc$4K
- Siemens Medical Solutions USA, Inc.$641
- AbbVie$243
- AstraZeneca$127
- Progenics Pharmaceuticals, Inc.$111
- plus $787 from 21 others
Across 40 payments — averaging $5812.38 each. Payments tied to a research study. These frequently flow through the physician to a hospital or research institution rather than to the physician personally.

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
$40,980 in reported general payments places this provider in the 90th percentile of 123 radiation oncology providers in Missouri.
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 | 64 | $868 |
| Oxycodone Hcl | 23 | $254 |

| Dexamethasone | 12 | $192 |
| Sodium FluorideFluoride (Sodium) | 16 | $94 |
