Summary
Blue Cross Blue Shield of Michigan is reminding providers that drug wastage modifiers JW and JZ are required when billing drugs in single-use containers for Medicare Plus Blue and BCN Advantage plans. This is a coding reminder to ensure proper billing practices.
Action Required
Immediately: Billing team must ensure all drug claims for single-use containers include appropriate wastage modifiers JW (for drug amount discarded/not administered) or JZ (for zero drug amount discarded) when billing Medicare Plus Blue and BCN Advantage plans. Update billing system edits and train staff on proper modifier usage to prevent claim denials.
