What this record shows
This record is dominated by education: $16 of the $16 with a category attached, or 100.0%. Every reported general payment came from a single manufacturer, Insmed, Inc.. That places this record below the midpoint for infectious disease clinicians in PA, where the typical reported total is $132.
Across 1 payment — averaging $15.50 each. Meals, travel, consulting and speaking fees, gifts and royalties reported by drug and device makers.
- Insmed, Inc.$16
Across 5 payments — averaging $43,355 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.

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 |
|---|---|---|
| Insmed, Inc. | 1 | $16 |
How this compares
$16 in reported general payments places this provider in the 25th percentile of 457 infectious disease providers in Pennsylvania.
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.
