Article Guidance

Article Text

Mutations found in sphingomyelin phosphodiesterase 1, (SMPD1) acid lysomal, are associated with Niemann-Pick Disease, characterized by acid sphingomyelinase (ASM) deficiency. For infants and children, SMPD1 genetic testing is used to confirm the clinical findings from blood tests to diagnose ASM. Genetic testing for adults is used to screen the population for potential carriers of the mutation. Therefore, Noridian has determined that SMPD1 genetic testing is not a Medicare benefit and is a statutorily excluded service. In addition to single disease testing, Noridian will also deny panels of tests that include a SMPD1 gene test as a statutorily excluded service.

To receive a SMPD1 test denial, please submit the following claim information:

  • CPT® code 81330- SMPD1, common variants
    CPT® code 81412 – Ashkenazi Jewish Associated Disorders
    • For a voluntary issued ABN, append with GX modifier
    • To indicate a statutorily excluded service, append with a GY modifier. An Advance Beneficiary Notice
      (ABN) is not required for statutorily excluded services
