Article Text

Effective for dates of services on and after 06/14/2012
The 4q25-AF Risk Genotype Test was developed to help predict the risk of atrial fibrillation and cardioembolic stroke. To date, there is insufficient evidence to support the required clinical utility for the established Medicare benefit category.

As reviewed, the developer described the indication to perform a 4q25-AF Risk Genotype Test as a risk assessment for developing a disease or condition. Risk assessment for developing a disease or condition in the absence of signs and symptoms of an illness or injury is also not defined as a Medicare benefit. Therefore, the 4q25-AF Risk Genotype Test would continue to be a statutory excluded service.

To receive a 4q25-AF Risk genotype service denial, please submit the following claim information:

  • CPT® code 81479 – Unlisted molecular pathology procedure
  • 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 the assigned DEX Z-codeTM Identifier adjacent to the CPT® code in the comment/narrative field for the following claim field/types:
    • Line SV202-7 for part A or Loop 2400 NTE02/SV101-7 for Part B
    • Block 80 for Part A or Box 19 for Part B on paper claim
