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.


Trio Whole Genome Sequencing
Whole Genome Sequencing
Test Details
Test Code: 1800
Test Includes: Whole Genome Sequencing includes coverage on all genes and currently reports on single nucleotide variants/indels (SNVs), copy number variants (CNVs), structural variants (SV) and absence of heterozygosity (AOH).

Special Notes: Whole Genome Sequencing can benefit patients who need a combination of comprehensive genetic testing (e.g. exome sequencing and CMA). Rather than ordering multiple tests, WGS can provide a patient with answers in one test.

Note: Parental samples are required to interpret trio WES results. See below and requisition for sample requirements and further details. Testing cannot be requested unless both parents submit samples for testing.
