CMS National Coverage Policy

Article Guidance

Article Text

Sulfotransferase 4A1 (SULT4A1) is an enzyme found in the brain that interacts with numerous neuroactive molecules, including some catecholamines and neural steroids. Findings suggest the SULT4A1-1 haplotype of SULT4A1 is associated with enhanced response to antipsychotic drug therapy. At present there is insufficient evidence to support SULT4A1 genotyping to determine medical management. Therefore, the MolDX Team has determined SULT4A1 genetic testing 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 SULT4A1 gene as a statutorily excluded service.

To receive a SULT4A1 test denial, please submit the following claim information:

  • CPT code 81479
  • An Advance Beneficiary Notice (ABN) is not required for statutorily excluded services
    • For a voluntary issued ABN, append with GX HCPCS modifier
    • To indicate a statutorily excluded service, append with a GY HCPCS modifier
  • 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
    • Box 19 for paper claim
  • Enter the appropriate 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
