The American Medical Association (AMA) Current Procedural Terminology (CPT) codes and Healthcare Common Procedure Coding System (HCPCS) codes listed, are provided for informational purposes only. The codes reflect our interpretation of CPT/HCPCS coding requirements based upon AMA guidelines published annually. CPT/HCPCS codes are provided only as guidance to assist clients with billing. Baylor Genetics strongly recommends that clients confirm CPT/HCPCS codes with their Medicare Administrative Contractor (MAC) or other payer being billed, as requirements may differ. CPT coding is the sole responsibility of the billing party. Baylor Genetics assumes no responsibility for billing errors due to reliance on the CPT codes listed. Please direct any questions regarding CPT coding to the payer being billed.

Targeted mtDNA Analysis by Massively Parallel Sequencing (MitoNGSSM)
Test Details
Test Code: 2056
Special Notes: This test can only be performed if there is a previously identified familial mutation or unclassified variant. A laboratory report containing the relative's mutation information, the specific biological relationship of this patient to the previously tested relative and the clinical status of this patient (symptomatic or asymptomatic) must be submitted with the specimen. If the original familial mutation was identified in another laboratory, this testing must be discussed with one of our genetic counselors prior to sending a specimen.

This analysis will provide targeted analysis and heteroplasmy quantification for mtDNA point mutations and unclassified variants. The detection threshold of massively parallel sequencing analysis for heteroplasmic mitochondrial DNA point mutations is approximately 1.5% for the Illumina HiSeq 2000 platform. This analysis will not provide heteroplasmy quantification for mtDNA large deletion and multiple deletions.
