Payments from drug & device makers
What this record shows
The money is spread across several categories — food and beverage (57.2%), travel and lodging and consulting fees — rather than concentrated in one kind of arrangement. 10 manufacturers reported payments, led by Zimmer Biomet at 43.8% of the total. 2025 is the largest year on record at $2,972, more than ten times the $151 reported in 2020.
Across 80 payments — averaging $97.79 each. Meals, travel, consulting and speaking fees, gifts and royalties reported by drug and device makers.

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.
Most prescribed under Part D
| Drug | Claims | Cost to plans & patients |
|---|---|---|
| Celecoxib | 28 | $555 |
| Oxycodone Hcl | 51 | $268 |
| Diclofenac Sodium | 12 | $250 |
| Meloxicam | 100 | $243 |
| Ibuprofen | 14 | $185 |
| Sulfamethoxazole-TrimethoprimSulfamethoxazole/Trimethoprim | 12 | $174 |
