Pathology and Laboratory: Genomic Sequencing Procedures and Other Molecular Multianalyte Assays (Q&A) (September 2018)
September 2018 page 15 Pathology and Laboratory: Genomic Sequencing Procedures and Other Molecular Multianalyte Assays Question: The laboratory offers deletion/duplication analysis for single gene analysis and various panels of genes via an array platform methodology. Should deletion/duplication analysis panels be handled in the same manner as the sequencing panels based on the genes being analyzed, or should code 81405, Molecular pathology procedure, Level 6 (eg, analysis of 6-10 exons by DNA sequence analysis, mutation scanning or duplication/deletion variants of 11-25 exons, regionally targeted cytogenomic array analysis), be reported for regionally targeted cytogenomic array analysis? Answer: The deletion/duplication CPT codes...
