Reminder: Appropriate Use of JW and JZ Modifiers

Highmark follows industry standards, consistent with Centers for Medicare and Medicaid Services (CMS) approach, requiring the appropriate use of the drug wastage modifiers JW and JZ. Drug wastage modifiers should be present on all applicable claims. For example, claims for drugs supplied in single-dose containers must include either the JW modifier to indicate waste or JZ modifier to attest that the full quantity was used.
