Summary & Overview
CPT 81425: Genome Sequencing for Unexplained Heritable Disorders
CPT code 81425 represents genome sequencing for patients with unexplained constitutional or heritable disorders, a critical tool in modern medical genetics. This procedure enables comprehensive analysis of a patient's genetic makeup, supporting diagnosis and management of complex syndromes and conditions. Nationally, genome sequencing is increasingly recognized for its role in identifying rare genetic disorders, guiding treatment decisions, and informing family planning.
Key payers covered in this publication include Aetna, Blue Cross Blue Shield, Cigna Health, and UnitedHealthcare. The report provides an overview of payer coverage, clinical benchmarks, and policy updates relevant to genome sequencing procedures. Readers will gain insight into the clinical context of 81425, including its use in laboratory settings, and understand how this code fits within broader genomic testing practices. The publication also addresses related codes, common modifiers, and associated taxonomies, offering a comprehensive resource for stakeholders interested in medical genetics billing and policy trends.
CPT Code Overview
CPT code 81425 is used to report genome sequencing procedures performed for patients with unexplained constitutional or heritable disorders or syndromes. This code falls under Pathology and Laboratory Procedures, specifically Genomic Sequencing Procedures and Other Molecular Multianalyte Assays. The typical site of service for this procedure is a laboratory (POS 81), where advanced genetic testing is conducted to identify potential genetic causes of complex medical conditions.
Clinical & Coding Specifications
Clinical Context
A patient presents with unexplained constitutional or heritable disorders, such as developmental delays, congenital malformations, or suspected genetic syndromes. The clinical workflow involves the ordering provider, often a medical geneticist, requesting a comprehensive genome sequencing procedure (81425) to identify potential genetic causes. The specimen is collected and sent to a specialized laboratory (Place of Service 81), where the sequencing and analysis are performed. Results are interpreted by professionals with expertise in medical genetics, and findings are reported back to the provider for further clinical management.
