CPT Code Overview
CPT code 81464 represents a genomic sequence analysis panel for solid organ neoplasms, specifically utilizing cell-free nucleic acid (such as plasma) to interrogate for sequence variants. This procedure falls under molecular pathology and genomic sequencing procedures within the field of pathology and laboratory medicine. The typical site of service for this test is a laboratory setting, designated as Place of Service 81. This advanced molecular diagnostic tool is used to detect genetic alterations in solid organ tumors, providing critical information for clinical decision-making and personalized treatment strategies.
Clinical & Coding Specifications
Clinical Context
A patient with a suspected or confirmed solid organ neoplasm, such as a malignant tumor of the lip or tongue, presents to their oncologist or surgeon. The clinician orders a genomic sequence analysis panel on cell-free nucleic acid (e.g., plasma) to interrogate for sequence variants. This test, represented by CPT code 81464, is performed in a laboratory setting (Place of Service 81). The results help guide diagnosis, prognosis, or targeted therapy decisions. The workflow involves specimen collection (typically blood), laboratory processing, and interpretation by a specialist in medical genetics or molecular pathology.
