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.


Hereditary High-Risk Breast Cancer Panel
Test Information: The Hereditary High-Risk Breast Cancer Panel analyzes 9 genes by the clinically validated approach of Massively Parallel Sequencing (MPS) using Next-Generation Sequence (NGS) technology to analyze selected genes associated with an increased risk for breast cancer. The genes analyzed by this panel can be found in the ?Gene Name? section.

Hereditary breast cancer accounts for approximately 5-10% of breast cancer cases. Approximately 25-50% of hereditary breast cancer cases have mutations in the BRCA1/2 genes. Additional high risk breast cancer genes include CDH1, PALB2, PTEN, STK11, and TP53. In general, the test is used when a patient's medical history and family history findings strongly suggest that there is an underlying genetic etiology of breast cancer. The panel can be used for confirmation of clinical diagnosis and differential diagnosis.
Test Details
Test Code: 23000
Special Notes: All coding exons of these genes and at least 20 base pairs of flanking intronic sequences are analyzed. All exonic variants and intronic variants within 20 bp of the exon/intron boundary will be reported. The NGS read depth is examined for evidence of large deletion/duplication mutations at the targeted genes. If detected, evidence of copy number change will be presented in the results and interpretation. For autosomal recessive conditions in which one mutation or at least one VUS is identified, read depth is specifically assessed.

While all regions are evaluated by NGS for possible copy number changes, variations in sample quality or the presence of pseudogenes or other homologous sequences may result in a signal to noise ratio that precludes analysis of some regions. Thus, NGS will not detect all copy number changes. A normal NGS analysis does not exclude the possibility of copy number changes of a gene or portion of a gene. 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.


A Hereditary Breast/Ovarian/Endometrial Cancer Panel is also available, which is more comprehensive and includes 27 genes associated with reproductive cancers.
