FANCC Genetic Testing Coding and Billing Guidelines (M00082, V2)

Effective for dates of service on and after February 6, 2013.

FANCC gene testing is performed in association with Fanconi anemia (FA), a condition characterized by physical abnormalities, bone marrow failure, and increased risk of malignancy. For infants and children, FANCC genetic testing is used to confirm the clinical findings, such as blood counts and bone marrow biopsy, to diagnose FA. Genetic testing for adults is used to screen potential carriers of the mutation. Therefore, MolDX  has determined that testing for the FANCC is not a Medicare benefit and is a statutorily excluded service. In addition to single gene testing, MolDX will also deny panels of tests that include the FANCC gene.

To receive a FANCC test denial, please submit the following claim information:

  • CPT code 81242- FANCC, common variant
  • An Advance Beneficiary Notice of Non-Coverage (ABN)External website is not required for statutorily excluded services.
    • For a voluntary issued ABN, append with HCPCS modifier GX
    • To indicate a valid ABN is on file for a known statutorily excluded service, append with HCPCS modifier GY
  • Select the appropriate diagnosis for the patient
  • For CPT non-NOC codes, Labs may either use the SV101-7 or SV202-7 (preferred) or the NTE field to submit this required information.
    • Enter the appropriate 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
