General Genetic Testing Criteria

Genetic testing is considered medically necessary to establish a molecular diagnosis of an inheritable disease when ALL the following are met:

  1. The member displays clinical features or phenotype of a defined genetic condition;
  2. The testing is necessary to establish a diagnosis for symptoms/conditions of unknown etiology
  3. The result of the test will directly impact the clinical decision-making or clinical outcome for the member
  4. The testing method is considered scientifically valid for the identification of a specific genetic condition
  5. Documentation is provided from a genetic counselor or physician with genetic expertise (e.g., medical geneticist, pediatric neurologist, developmental pediatrician) who supports the recommendation for testing based on a review of risk factors, clinical scenario, and family history AND that appropriate genetic counseling has been delivered.
  6. For testing codes noted below, all relevant coverage criteria need to be met.

These criteria may not apply to testing for familial cancer syndromes. Separate criteria are used
for BRCA 1 and 2 testing and the 21-gene RT-PCR assays. Other tests for familial cancer
syndromes will be subject to criterion 1-6 below, but will also be assessed for consistency with
best medical practice. Criteria published by the National Cancer Care Network (NCCN) and
the Centers for Medicare and Medicaid Services may apply to the evaluation of testing for
familial cancer syndromes, when available.

Genetic Testing Not Covered

Genetic testing is not medically necessary to determine a specific diagnosis or syndrome when
such diagnoses would not definitively alter the medical treatments of the member.
Genetic testing is not medically necessary to determine the likelihood of associated medical
conditions occurring in the future when the diagnosis of the condition can be made by other
testing.

Genetic testing is not medically necessary for the purposes of determining current or future
family planning. Genetic testing is not covered for the purpose of investigating if a condition
might affect the member’s children or other family members if the diagnosis does not directly
affect the medical treatment of the member.

Genetic testing is not medically necessary for members without a medical condition or at risk
for any condition which can only be confirmed with genetic tests.

      acquired function or fails to progress beyond a plateau following a period of normal
      development; OR
    5. Presence of epilepsy or a seizure disorder for which a genetic etiology is suspected
      and standard medical evaluation has not been diagnostic; AND
  5. No other causative circumstance such as environmental exposure, injury, or infection can account for the clinical presentation; AND

    WES reanalysis of previously obtained standard WES for one of the above medically necessary

      assessed during the original exome evaluation; OR
    2. The birth or diagnosis of a similarly affected first-degree relative that has expanded the

      unexplained ID, DD, or autism or in females with these conditions when strong
      clinical suspicion is documented due to phenotype or family history.
    2. Codes specific for members with high-risk pregnancies such as women older than 35
      years of age or part of an ethnic or religious population known to carry a high risk
      of defective genes will be considered for approval where there is adequate
