MolDx: Molecular Test Registration Requirement for Hospital Laboratories

Effective March 1, 2017, hospitals submitting claims (5010A1-837I) for molecular tests must first register in the Diagnostics Exchange. Once registered, hospital laboratories must enter the molecular tests they perform (See Molecular Diagnostic Program (MolDX) (M00106)) for applicable CPT codes (MolDX Manual to receive a Z-Code assignment. If a hospital laboratory sends out testing to a reference laboratory, the hospital laboratory will request to share the reference laboratory’s test-specific DEX Z-Codes™.
