Summary & Overview
CPT 81427: Reevaluation of Full Genomic Sequence Analysis
CPT code 81427 represents the reevaluation of a patient's full genomic sequence analysis by a laboratory analyst, prompted by new clinical information or evidence of an unrelated condition that was not available during the initial evaluation. This procedure is a critical component of genomic medicine, enabling clinicians to update genetic interpretations as new data emerges, which can impact patient management and treatment decisions. The code is categorized under Genomic Sequencing Procedures and Other Molecular Multianalyte Assays, reflecting its role in advanced molecular diagnostics.
Major national payers, including Aetna, Blue Cross Blue Shield, Cigna Health, and UnitedHealthcare, provide coverage for this service, underscoring its widespread clinical relevance. Readers will gain insight into payer coverage benchmarks, recent policy updates, and the clinical context for the use of 81427. The publication also explores associated taxonomies, common modifiers, and related CPT codes, offering a comprehensive overview of how this code fits into the broader landscape of medical genetics and laboratory services.
This summary provides a clear understanding of the importance of 81427 in the evolving field of genomic medicine, highlighting its utility for ongoing patient care and its recognition by leading health insurers.
CPT Code Overview
CPT code 81427 is used when a laboratory analyst reevaluates an existing patient full genomic sequence analysis in light of new information that was not available at the time of the initial evaluation. This may include new clinical information or evidence of an unrelated condition. The service falls under Genomic Sequencing Procedures and Other Molecular Multianalyte Assays and is typically performed in a laboratory setting (Place of Service 81). This code is essential for updating and refining genetic assessments as new data emerges, supporting ongoing patient care and precision medicine.
Clinical & Coding Specifications
Clinical Context
A patient previously underwent full genomic sequencing to evaluate for genetic risk factors or unexplained clinical findings. New clinical information has emerged, such as updated family history, new symptoms, or evidence of an unrelated condition. The laboratory analyst is requested to reevaluate the patient's existing genomic sequence in light of this new information. This process is performed in a laboratory setting (Place of Service 81) and typically involves specialists in medical genetics. The workflow includes reviewing the original genomic data, integrating new clinical or genetic evidence, and providing an updated interpretation to inform patient management.
