Payments from drug & device makers
What this record shows
The money is spread across several categories — food and beverage (50.4%), consulting fees and speaking fees — rather than concentrated in one kind of arrangement. It is spread thinly across 48 manufacturers, the largest accounting for just 19.9%. Among interventional pain medicine clinicians in MD 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 1,321 payments — averaging $46.66 each. Meals, travel, consulting and speaking fees, gifts and royalties reported by drug and device makers.
- Abbott$12K
- Vertos Medical, Inc.$12K
- Medtronic$9K
- Nevro Corp.$5K
- Boston Scientific$5K
- Stryker$4K
- plus $14K from 42 others
Across 11 payments — averaging $991.49 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.
- Si-bone, Inc.$11K
What the payments were for
- Consulting fees$17,44028%
- Speaking & faculty fees$7,95513%
- Travel & lodging$5,1618%
- Food & beverage$31,07850%
- Education$40%
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.

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.
