Article Guidance

Article Text

Effective for dates of service on and after January 29, 2013


PAX6 is most frequently associated with PAX6-associated aniridia and WAGR syndrome (predisposition to Wilms tumor, Aniridia, Genitourinary anomalies and mental Retardation). Because FISH probes are reported to detect 100% of the WAGR syndrome cases, FISH probes represent the gold standard for patient diagnosis. Although PAX6 sequencing will identify the underlying genetic mutation leading to the development of aniridia in approximately 50% of individuals with sporadic disease, the remaining 50% will have negative test results. Therefore, the MolDX Team has determined PAX6 gene sequencing does not support the required clinical utility for the established Medicare benefit category and is a statutorily excluded test.

To receive a PAX6 gene sequencing service 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 modifier
    • To indicate a 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

Added “Title XVIII of the Social Security Act, §1862(a)(1)A) allows coverage and payment for only those services that are considered to be reasonable and necessary for the diagnosis or treatment of illness or injury or to improve the functioning of a malformed body member” to the CMS National Coverage Policy section of this article. Under Article Title changed title from Billing and Coding: MolDX: PAX6 Gene Sequencing Coding and Billing Guidelines to Billing and Coding: MolDX: PAX6 Gene Sequencing. Under Article Text removed the reference to the regulation Title XVIII of the Social Security Act, §1862 (a) (1) (A) Statutory Exclusion covers diagnostic testing “except for items and services that are not reasonable and necessary for the diagnosis or treatment of illness or injury or to improve the functioning of a malformed body member,…” and removed the sentence “Select the appropriate diagnosis for the patient.” Modifiers GY and GX were added to the Modifier Section.
