What DAW code means that no product selection is indicated and substitution is allowed?

The DAW (Dispense As Written) code that signifies "no product selection is indicated and substitution is allowed" is 0. This code tells pharmacies and insurers that the prescriber has not specified a particular brand or product, allowing pharmacists the discretion to substitute the medication with a generic equivalent or a different brand that is therapeutically equivalent, as long as the substitution aligns with the patient's needs and the relevant regulations.

In practice, when DAW code 0 is used, it indicates flexibility in dispensing and facilitates the use of potentially lower-cost options for patients. This choice is crucial for cost management and accessibility for patients, as it enables pharmacists to make decisions based on availability and cost-effectiveness while still adhering to the prescribed treatment plan.
