Payments from drug & device makers
What this record shows
This record is dominated by food and beverage: $118 of the $149 with a category attached, or 79.6%. 5 manufacturers reported payments, led by Medtronic at 55.0% of the total. 2025 is the largest year on record at $82, 3.8 times the $21 reported in 2019. That places this record below the midpoint for cardiovascular disease clinicians in CA, where the typical reported total is $2,142.
Across 5 payments — averaging $29.71 each. Meals, travel, consulting and speaking fees, gifts and royalties reported by drug and device makers.
- Medtronic$82
- Atricure, Inc.$30
- AstraZeneca$17
- Abbott$15
- Cardiovascular Systems Inc.$5
Across 4 payments — averaging $1147.55 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.

What the payments were for
- Travel & lodging$3020%
- Food & beverage$11880%
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.
| Company | Payments | Total |
|---|---|---|
| Medtronic | 1 | $82 |
| Atricure, Inc. | 1 | $30 |
| AstraZeneca | 1 | $17 |
| Abbott | 1 | $15 |
| Cardiovascular Systems Inc. | 1 | $5 |
How this compares
$149 in reported general payments places this provider in the 10th percentile of 2,184 cardiovascular disease providers in California.
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 |
|---|---|---|
| EliquisApixaban | 35 | $44,772 |
| Metoprolol Succinate | 45 | $691 |
| Flecainide Acetate | 15 | $552 |
| Amiodarone Hcl | 25 | $333 |
| Hydrocortisone | 11 | $71 |
| Atorvastatin Calcium | 11 | $20 |
