Payments from drug & device makers
What this record shows
Almost everything reported here is food and beverage — 100.0% of the total across 114 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 17 manufacturers, the largest accounting for just 17.9% — the pattern of someone who eats at a lot of different presentations. 2025 is the largest year on record at $1,422, more than ten times the $45 reported in 2023. Among nurse practitioner clinicians in MI 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 114 payments — averaging $19.45 each. Meals, travel, consulting and speaking fees, gifts and royalties reported by drug and device makers.

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.
How this compares
$2,217 in reported general payments places this provider in the 90th percentile of 3,351 nurse practitioner providers in Michigan.
