Payments from drug & device makers
What this record shows
This record is dominated by food and beverage: $1,196 of the $1,537 with a category attached, or 77.8%. Stryker accounts for 82.1% of it on its own, with 7 other manufacturers making up the rest. Reporting peaked in 2022 at $760 and has fallen 54.8% since, to $343 in 2024. That places this record below the midpoint for orthopaedic surgery clinicians in MT, where the typical reported total is $1,701.
Across 25 payments — averaging $61.50 each. Meals, travel, consulting and speaking fees, gifts and royalties reported by drug and device makers.

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.
| Company | Payments | Total |
|---|---|---|
| Stryker | 18 | $1,262 |
| Innovation Technologies Inc | 1 | $123 |
| Microport Orthopedics Inc | 1 | $43 |
| Heron Therapeutics, Inc. | 1 | $30 |
| Steelhead Surgical Inc | 1 | $27 |
| Vericel Corporation | 1 | $21 |
| Johnson & Johnson | 1 | $20 |
| Bioventus LLC | 1 | $11 |
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.
- BLUEPRINT PATIENT SPECIFIC INSTRUMENTATION$327
- TRIATHLON$227
- NA$133
- Irrisept$123
- GAMMA$117
How this compares
$1,537 in reported general payments places this provider in the 45th percentile of 76 orthopaedic surgery providers in Montana.
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 | 110 | $4,274 |
| Oxycodone Hcl | 74 | $525 |
| Hydrocodone-AcetaminophenHydrocodone/Acetaminophen | 26 | $268 |
| Meloxicam | 45 | $233 |
| Methocarbamol | 38 | $204 |
| Omeprazole | 15 | $147 |
