Important Reminder for Part A Providers About MolDX Claim Submission

Effective December 1, 2017, claims submitted without a Z-Code will be rejected. Part A providers billing for molecular services have been advised to register for a DEX Z-Code identifier for each molecular test for which they bill Medicare. If a DEX Z-code has not already been obtained, go to DEX Diagnostics ExchangeTM and select 'register your organization.' For more information about the MolDX program, please visit the MolDX website.
