Payments from drug & device makers
What this record shows
This record is dominated by food and beverage: $269 of the $387 with a category attached, or 69.4%. Amgen accounts for 63.0% of it on its own, with 1 other manufacturer making up the rest.
Across 5 payments — averaging $77.46 each. Meals, travel, consulting and speaking fees, gifts and royalties reported by drug and device makers.
- Amgen$244
- Novartis$143
What the payments were for
- Food & beverage$26969%
- Education$11831%
Most of this is food and beverage — typically meals provided during product presentations at a clinic or hospital. Nationally that is the single largest category of reported payments by count.
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.
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.
- EVENITY$118
How this compares
$387 in reported general payments places this provider in the 70th percentile of 50 rheumatology providers in Iowa.
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.
