Billing and Coding: MolDX: Molecular Testing for Identification and Management of Hereditary Transthyretin Amyloidosis

This billing/coding guideline complements LCD DL39987 for molecular testing to identify and manage hereditary transthyretin amyloidosis; testing should follow the LCD clinical criteria. Only one test may be billed per patient with one unit of service; the appropriate CPT and ICD-10-CM codes must be reported and the DEX Z-Code identifier must be entered adjacent to the CPT in specified claim fields (Part B: Loop 2400 or SV101-7 for electronic, Box 19 for paper; Part A: SV202-7 for 837I electronic, Block 80 for UB04). Do not add extra characters to the SV101-7 line when entering the DEX Z-Code.
