General payments by program year
Who reported the general payments

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 |
|---|---|---|
| Lilly USA, LLCMounjaro | $209 | $38,56130 claims |
| PfizerEliquis | $224 | $24,57425 claims |
| AstraZenecaFarxiga | $723 | $19,85029 claims |

| Phathom Pharmaceuticals, Inc.Voquezna | $360 | $8,88414 claims |
| AbbVieSynthroid | $688 | $57317 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 90th percentile of 3,912 physician assistant providers in Illinois.
