Payments from drug & device makers
What this record shows
Almost everything reported here is food and beverage — 100.0% of the total across 79 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 32 manufacturers, the largest accounting for just 13.4% — the pattern of someone who eats at a lot of different presentations.
Across 79 payments — averaging $20.07 each. Meals, travel, consulting and speaking fees, gifts and royalties reported by drug and device makers.

How this compares
$1,586 in reported general payments places this provider in the 70th percentile of 22 radiation oncology providers in Idaho.
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 | 118 | $1,827 |
| Venlafaxine Hcl ErVenlafaxine Hcl | 14 | $211 |
| Hydrocodone-AcetaminophenHydrocodone/Acetaminophen | 13 | $179 |
