Payments from drug & device makers
What this record shows
This record is dominated by consulting fees: $9,897 of the $11,120 with a category attached, or 89.0%. Biogen accounts for 82.3% of it on its own, with 2 other manufacturers making up the rest. 2024 is the largest year on record at $9,147, more than ten times the $750 reported in 2019. Among geriatric medicine clinicians in PA with any reported payments, this total sits in the top 5% — high for the specialty, which is a reason to read the composition above rather than the number alone.
Across 9 payments — averaging $1235.57 each. Meals, travel, consulting and speaking fees, gifts and royalties reported by drug and device makers.

- Janssen Research & Development, LLC$750
Across 11 payments — averaging $77,682 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.

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 |
|---|---|---|
| Biogen | 1 | $9,147 |
| Eli Lilly | 7 | $1,223 |
| Janssen Research & Development, LLC | 1 | $750 |
How this compares
$11,120 in reported general payments places this provider in the 95th percentile of 217 geriatric medicine 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.
Most prescribed under Part D
| Drug | Claims | Cost to plans & patients |
|---|---|---|
| Donepezil Hcl | 17 | $287 |
| Sertraline Hcl | 22 | $226 |
