Payments from drug & device makers
What this record shows
Almost everything reported here is food and beverage — 100.0% of the total across 107 separate payments, which is the pattern of a clinician who attends manufacturer presentations rather than one with a consulting arrangement. AbbVie accounts for 60.6% of it on its own, with 16 other manufacturers making up the rest. Reporting peaked in 2021 at $560 and has fallen 84.3% since, to $88 in 2025.
Across 107 payments — averaging $12.51 each. Meals, travel, consulting and speaking fees, gifts and royalties reported by drug and device makers.

Paid to pharmacies, not to this prescriber.
Companies that both paid and supply prescribed drugs
These companies both reported payments to this provider and make drugs the provider prescribed under Medicare Part D in 2024. For most specialties this overlap is expected — a cardiologist who is paid by a cardiology drugmaker also treats heart disease. It is shown so the reader can see it, not because it implies anything on its own.
| Company | Paid to this provider | Part D cost of their drugs |
|---|---|---|
| Collegium Pharmaceutical, Inc.Xtampza Er | $17 | $40,21949 claims |
| PfizerEliquis | $66 | $17,92512 claims |
| AbbVieArmour Thyroid, Synthroid | $811 | $3,47535 claims |
Reading this fairly. The Part D column is what drug plans and patients paid pharmacies — this provider received none of it, and it reflects how many patients they treat and what those drugs cost. Against peers, this provider's reported payments sit in the 80th percentile of 5,182 internal medicine providers in Illinois.
