DEX Test Registration and Claims Submission (M00148, V14) – 8-17-2020 Update

The claim line for molecular diagnostic tests must contain the appropriate CPT code and test identifier (DEX Z-Code) associated with the test. 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.
