Summary
Effective June 1, 2026, Anthem Commercial plans in New York are requiring revised claim submission for single-dose vials to align with Medicare standards. Providers must now submit two separate claim lines when drug waste occurs: one line showing quantity administered (no modifier) and a second line showing discarded amount (JW modifier). When no waste occurs, submit a single line with JZ modifier. This change affects how pharmaceutical waste is billed and reimbursed.
Action Required
Before June 1, 2026: Billing team must implement changes to claim submission processes for single-dose vial billing. (1) Update billing software or templates to require two separate claim lines when drug waste is present: first line with administered quantity (no modifier), second line with JW modifier for discarded amount. (2) Configure system to submit single claim line with JZ modifier when no waste occurs (full dose administered). (3) Train all billing and clinical staff on correct JW and JZ modifier usage to prevent claim denials. (4) Implement documentation procedures to capture and reconcile drug administration and wastage records to support accurate billing. (5) Audit existing single-dose vial claims in billing system to identify any that need reprocessing under new guidelines before effective date. Reference Commercial reimbursement policy C-11031 for detailed requirements. Failure to implement correct modifier usage will result in claim denials and revenue loss.
