RPS19 Gene Tests Coding and Billing Guidelines (CM00072)

Effective for dates of service on and after June 25, 2013.

RPS19 gene sequencing, deletion/duplication and known familial mutation analysis may be performed during the diagnosis of Diamond-Blackfan Anemia (DBA). Since clinical symptoms and diagnosis usually occur prior to Medicare eligibility and carrier testing is not a covered benefit, MolDX has determined RPS19 analysis is a statutorily excluded test. MolDX will also deny tests that include one or more of RPS19 analysis reported with CPT code 81479 as statutorily excluded services.

To receive a RPS19 analysis service denial, please submit the following claim information:

  • Select appropriate CPT code according to genetic material tested
    • CPT code 81403 for known familial variant, not otherwise specified
    • CPT code 81405 for gene sequencing
    • CPT code 81479 for combinations of RPS19 analysis
  • 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
  • Enter the appropriate identifier adjacent to the CPT code in the comment/narrative field for the following claim field/types:
    • Part A: Loop 2300 NTE 01 (electronic claim); Form Locator 80 (paper claim)
    • Part B: Loop 2400 or SV101-7 (electronic claim); Item 19 (paper claim)
