Article Guidance

Article Text

L1 syndrome refers to multiple disorders including X-linked hydrocephalus with aqueduct of Sylvius (HSAS) stenosis, MASA syndrome (Mental retardation, Aphasia, Spastic paraplegia, Adducted thumbs), SPG1 (X-linked complicated hereditary spastic paraplegia type 1), and X-linked complicated corpus callosum agenesis. Because there are many potential underlying causes for congenital hydrocephalus, including syndromic and nonsyndromic cases, recurrence risk and implications for family members is based upon underlying etiology. Genetic testing of the L1CAM gene is used to confirm a clinical diagnosis and provide recurrence risk. Therefore, the MolDX Contractor has determined L1CAM full gene sequencing is a statutorily excluded test.

To receive a L1CAM gene sequencing service denial, please submit the following claim information:

  • CPT code 81407-L1CAM
  • CPT code 81470- X-linked intellectual disability genomic sequence analysis panel
  • CPT code 81471- X-linked intellectual disability genomic sequence analysis panel duplication / deletion
    • For a voluntary issued ABN, append with GX modifier
    • To indicate a valid ABN is on file for a known statutorily excluded service, append with a GY modifier. An Advance Beneficiary Notice (ABN) is not required for statutorily excluded services.
  • 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
    • Item 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

Revision History Information

Revision History DateRevision History NumberRevision History Explanation
12/17/2021 R3

Noridian has modified certain language in this article to mirror the language used presently by the MolDX team at PalmettoGBA as part of an annual review. Revision history dates and language may not exactly match the MolDX PGBA revision history but is updated with the revisions made in an accurate timeline. However, these revisions do not change coverage or guidance.

This article is being revised in order to adhere to CMS requirements per chapter 13, section 13.5.1 of the Program Integrity Manual, to remove all coding from LCDs and incorporate into related Billing and Coding Articles. Added “SSA §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 title was changed to “Billing and Coding: MolDX: L1CAM Gene Sequencing”. Under CPT/HCPCS Codes created Group 2: Paragraph and added verbiage “HCPCS codes that are also referenced in other articles”. Created Group 2: Codes and moved CPT® 81407 from Group 1: Codes to Group 2: Codes. Under the CPT/HCPCS Modifiers section Group 1: Codes modifiers GY and GX were added. The description of CPT® code 81407 has been changed. The revision for the code descriptor is due to the Quarter 4 CPT®/HCPCS updates and was effective on 10/1/2019.

12/01/2019 R2

As required by CR 10901, article is converted to a formal billing and coding type article. There is no change in coverage. CPT code 81407 is moved to a second code grouping, noting it is also referenced in other articles.

01/01/2019 R1

Article is revised to add CPT codes 81470 and 81471 per the 2019 Annual HCPCS Code Update.
