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.


Rapid Duo Whole Genome Sequencing
Test Information: Whole Genome Sequencing (WGS) is a highly complex, comprehensive genetic test that looks at the entire human genome (up to 98%), as opposed to only the exome (the coding regions of human DNA), which only accounts for about 2% of the human genome or at only specific genes. With this level of coverage, WGS has the advantage of being a single test that can detect genetic variants that may not be recognized from a test that is highly specific or only targets the exome.

WGS includes coverage on all genes and currently reports on single nucleotide variants/indels (SNVs), copy number variants (CNVs), structural variants (SV), absence of heterozygosity (AOH), mitochondrial variants and trinucleotide repeats.

This is recommended for patients who are critically ill with an undiagnosed genetic syndrome who need a rapid turnaround time for results.
Test Details
Test Code: 1823
Special Notes: Parental sample is required to interpret duo WGS results. See below and requisition for sample requirements and further details. Testing cannot be requested unless the parent submits sample for testing.

The turnaround time begins when the patient's sample arrives at the BG Lab. Some results may require confirmatory studies, which will cause additional time of reporting.
