Still Have Questions About Using the JZ/JW Modifier Starting July 1?

Beginning July 1, all claims for single-dose Part B drugs administered to original Medicare patients must include a JW modifier to indicate unused volume of drug or a new JZ modifier to indicate the entire volume of the drug was used. 

This policy was included in the 2023 Medicare Physician Fee Schedule Final Rule as CMS began implementation of a new law that requires manufacturers to rebate Medicare for un-sued, discarded volume of Part B drugs. Additional information on the policy is available on the ASRS website. 

The Medicare Administrative Contractor First Coast Service Options provides helpful billing examples here. If you have questions, please contact ASRS Director of Practice Management, Monica Horton.
