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.


Common Hereditary Cancer Panel
Test Information: Confirmation of Clinical Diagnosis, Differential Diagnosis

The Common Hereditary Cancer Panel uses next-generation sequencing and deletion/duplication analysis to simultaneously analyze selected genes associated with an increased risk for various cancers.
Test Details
Test Code: 24000
Special Notes: Twenty-seven genes involved in this panel are analyzed by the newly developed and clinically validated approach of Massively Parallel Sequencing (MPS) using Next Generation Sequence (NGS) technology. The genes analyzed by this panel are tabulated below. Sequencing of these genes is also available using the associated individual test codes.

APC, ATM, BARD1, BMPR1A, BRCA1, BRCA2, BRIP1, CDH1, CDK4, CDKN2A, CHEK2, 1*EPCAM, MLH1, MRE11A, MSH2, MSH6, MUTYH, NBN, PALB2, PMS2, PTEN, RAD50, RAD51C, RAD51D, SMAD4, STK11 and TP53

For the copy number analysis, single/multiple exon deletions or consecutive exon duplications can be detected at >97% (95% CI, 75.8-100%, N=12) analytical sensitivity. Note that NGS based copy number variation (CNV) analysis can be impacted by sample quality, characteristics of targeted regions (GC content, presence of homologous sequences, etc.) and other technical variations. Read depth analyses that are either uninformative or unsupportive of a copy number change do not exclude large deletions or duplications. Thus, targeted oligonucleotide array CGH analysis (test code 2001 for a single locus and 2003 for multiple loci included in this panel) may be warranted if intragenic deletions/duplications are suspected. Samples not meeting the quality control requirement for NGS CNV analysis are also recommended for additional testing using alternative methodologies. In addition, multiplex ligation-dependent probe amplification (MLPA) and/or array comparative genomic hybridization (aCGH), performed on a targeted oligonucleotide array CGH (PanelArr), may be used to assess or confirm copy number changes involving gene(s) in this panel. Certain genes or exons in some genes (e.g., PMS2, CHEK2, etc.) with highly homologous sequences in the genome will not be evaluated for copy number variations by the above analyses. Findings are reported according to human genome build hg19. This assay will not detect balanced translocations, inversions, low level mosaicism, uniparental disomy, and imprinting defects.

The genes included the Hereditary Breast/Ovarian/Endometrial Cancer Panel (TC 22404)*, Hereditary High Risk Colorectal Cancer (TC 23204), Hereditary Pancreatic Cancer (TC 23304), Hereditary Prostate Cancer (TC 23404), & Hereditary Colorectal/Gastrointestinal Cancer Panel (TC 22804)* panels are included in the Common Hereditary Cancer panel (TC 24000).

1Only copy analysis for this gene will be reported since there are no known sequencing variations associated with cancer in this gene.

*Genes ENG and PMS1 are not included in the Common Hereditary Cancer Panel (TC 24000)
