Article Text

Effective for dates of service on and after July 24, 2013

ATP7B gene mutations have been primarily associated with Wilson Disease, a disorder of copper metabolism. However, serology remains the gold standard for testing and treating the signs and symptoms of this condition. At present the literature does not support that ATP7B gene testing changes physician treatment or improves patient outcomes. Therefore, the MolDX Team has determined ATP7B gene testing is a statutorily excluded service. MolDX will also deny panels of tests that include the ATP7B gene.

To receive an ATP7B gene test denial, please submit the following claim information:

    • Select the appropriate CPT® code for the performed service:
      • 81406 - ATP7B, fgs
      • 81443 - Genetic Testing for severe genetic conditions
      • 81479 - Unlisted molecular pathology procedure
    • An Advance Beneficiary Notice (ABN) is not required for statutorily excluded services.
      • For a voluntary issued ABN, append with GX modifier
      • To indicate a valid ABN is on file for a known statutorily excluded service, append with a GY modifier
    • Enter DEX Z-Code™ identifier adjacent to the CPT® code in the comment/narrative field for the following Part B claim field/types:
      • Loop 2400 or SV101-7 for the 5010A1 837P
      • Box 19 for paper claim
    • Enter DEX Z-Code™ identifier adjacent to the CPT® code in the comment/narrative field for the following Part A claim field/types:
      • Line SV202-7 for 837I electronic claim
      • Block 80 for the UB04 claim form
