The common 340B inventory model is a Replacement model. In this model, pharmacies fill prescriptions from their existing stock and manage their inventory like usual; third-party 340B administrators then reconcile medications dispensed to 340B patients, and replenish the pharmacyâ€™s stock using the covered entityâ€™s 340B drugs.
Another, much more efficient way, is the Direct Model, a clean-and-cut 340B management model where pharmacies fill prescriptions from a physically separate 340B stock of drugs, eliminating the third-party administrator, and greatly reducing potential for error and fraud
At IMC we have experienced both methods of madness when it comes to 340B management theories. From the eyes of a company on the counting end both work, although the second model does seem more accurate but we would bet requires much more work on the pharmacies end.
