Final answer:
ODB may reimburse the higher cost interchangeable drug if the prescriber has written 'No Sub'. This requires that the drug being prescribed is an interchangeable drug, it is higher cost compared to the generic drug, and the prescriber has written 'No Sub' on the prescription.
Step-by-step explanation:
The requirements to be met for ODB to reimburse the higher cost interchangeable drug when the prescriber has written 'No Sub' are as follows:
- The drug must be an interchangeable drug, meaning it can be substituted for the prescribed drug.
- The drug must be higher cost compared to the generic drug.
- The prescriber must have explicitly written 'No Sub' on the prescription, indicating that substitution should not be allowed.
If all these requirements are met, ODB may reimburse the higher cost interchangeable drug.
