Payments from drug & device makers
What this record shows
Almost everything reported here is food and beverage — 100.0% of the total across 45 separate payments, which is the pattern of a clinician who attends manufacturer presentations rather than one with a consulting arrangement. 8 manufacturers reported payments, led by Johnson & Johnson at 34.9% of the total. Reporting peaked in 2019 at $477 and has fallen 54.6% since, to $217 in 2025. Among hospitalist clinicians in AZ 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 45 payments — averaging $24.36 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 |
|---|---|---|
| Johnson & Johnson | 14 | $383 |
| ZOLL Services LLC (a/k/a ZOLL Lifecor Corp) | 4 | $247 |
| Merck | 8 | $132 |
| Novartis | 6 | $123 |
| Pfizer | 7 | $113 |
| Philips North America LLC | 3 | $54 |
| AstraZeneca | 2 | $27 |
| Medtronic | 1 | $19 |
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.
- LifeVest$123
How this compares
$1,096 in reported general payments places this provider in the 90th percentile of 578 hospitalist providers in Arizona.
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.
