* Product-associated amounts are non-additive because one payment record may name more than one product.
These products were named on specific Open Payments records. A named product does not show that the payment influenced treatment or prescribing.
| Open Payments product | Payment year | Part D brand | Part D year | Claims | Match method | Source |

| PAXLOVID paxlovid |
2025 | Paxlovid | 2024 | 14 | exact normalized | Medicare Part D |
The presence of the same drug in both datasets does not show that a payment caused or influenced a prescription.
Analysis 2 · Same-company prescribing overlap
This analysis is independent from products named on this doctor’s individual payment records. A row appears only when the exact Open Payments reporting entity paid this doctor, that same reporting entity reported the drug or biological on at least 10 loaded General Payment records involving at least 2 distinct recipient NPIs, and this doctor has the same non-generic brand in public Part D data. This does not mean the company owns or manufactures the drug.
