Microarray Billing Policy

When the new molecular CPT codes became effective January 1, 2013, insurance companies subsequently revised their medical policies regarding medical necessity for chromosomal microarray.  Because of the variability among these policies, waivers for microarray testing have been implemented for all insurance carriers, except Colorado Medicaid.  

If charges for microarray are to be billed to the patient's insurance:

  • Pre-authorization is strongly recommended.  Please provide a copy of the prior authorization with the specimen submitted for microarray testing.
  • Have the patient complete and sign the Waiver for CytoSNP-850K Microarray form below, and submit it with the specimen for microarray testing.  If the patient’s insurance denies the charges, the patient will be billed at a discounted rate.

Policy for Familial Follow-up After Abnormal Microarray

It is recommended that parental testing be considered when a genomic imbalance is detected by chromosomal microarray to determine if the finding is an inherited or de novo occurrence.

Depending on the specific imbalance, follow-up testing may be FISH studies, cytogenetic analysis (karyotyping), or targeted microarray.

  • If the parental/familial testing will help clarify the clinical significance of the imbalance, testing of two family members will be offered at NO CHARGE within 13 months of CMA report date.
  • For all other cases, testing is available at CGL for an additional charge. The Waiver for Targeted CytoSNP-850K Microarray form below must be completed and signed by the patient, and submitted with the specimen for targeted microarray testing. If the patient's insurance denies the charges, the patient will be billed at a discounted rate.

Waiver for Targeted Microarray

If you have questions or would like to discuss follow-up testing in the context of a particular patient case, please contact CGL at (303) 724-5701 and ask to speak with a Genetic Counselor.
