If a prescriber allows generic substitutions, which DAW code would likely be used?

When a prescriber allows for generic substitutions, the appropriate DAW (Dispense As Written) code that would be used is DAW 0. This code indicates that the patient has no request for a brand name drug when a generic equivalent is available, and it signals to the pharmacy that they may dispense a generic version without needing to obtain prior authorization or approval from the prescriber.

In scenarios where a prescriber prefers a specific brand name medication to be dispensed despite generics being available, a different code would be used. DAW 1 is utilized in those cases, meaning the prescriber explicitly requests the brand name. DAW 2 indicates that the patient is requesting the brand name drug even though generics are available, while DAW 3 means that a generic was available but the pharmacy did not have it in stock at the time of dispensing. These alternative codes reflect situations where generic substitutions are either not allowed or where additional considerations are required. Thus, DAW 0 is the clear choice when generic substitutions are allowed by the prescriber.
