Summary
Blue Cross of Idaho updated their drug waste billing policy to require the JZ modifier when no drug waste occurs. Providers must now use JZ modifier on drug billing lines when the entire contents of single-dose vials are administered with no discarded amounts.
Action Required
Immediately: Billing team must update coding procedures to append JZ modifier to drug billing lines when no drug waste occurs (entire single-dose vial contents administered). Train staff to use JW modifier for wasted portions and JZ modifier when no waste. Update billing software and encounter forms to prompt for appropriate modifier selection based on waste status.
