MolDX Molecular Test Registration and Claims Submission (M00148, V13)

November 14, 2018

Every molecular test billed by any laboratory or facility within MolDX and our Medicare-partner jurisdictions must obtain a Z-code for each molecular test prior to claim submission.  To access and obtain a DEX Z-codeTM identifier, follow these steps

  • Go to the DEX Diagnostics ExchangeTMhttps://app.dexzcodes.com  
  • Select “Register My Organization” and follow the prompts, including participation in the MolDX program
  • Within 10 business days of registering with DEX, you will receive a welcome email with a link to set your password and a getting started guide
  • Once you have received the email and activated your login, you will have access to add test information
  • Within 45 business days of entering specific test information, the DEX Z-CodeTM identifier will be assigned to tests. DEX will send an email to you when the DEX Z-Code has been assigned.
  • Please note: we recommend waiting 2–3 weeks before adding this Z-Code to your claim

Once DEX assigns a Z-Code, it is not effective until the MolDX team has reviewed your test application to determine coverage and assigned a CPT code. The CPT code you submit with your application is not necessarily the CPT code that MolDX will assign to your test. You must submit the correct combination of Z-Code, CPT code, and NPI in order for claims to be paid.
