Emergency supply

In the event a member needs to begin therapy with a noncovered medication before you can obtain prior authorization, pharmacies are authorized to dispense up to a 72-hour emergency supply.

The pharmacy must enter a "3" in the Level of Service field (418-DI) to indicate that the transaction is an emergency fill. The claims will only allow a 72-hour supply. Emergency fills will be exempt from copayments.
