Cytogenomic Microarray Analysis for Neoplasia (February 2020)
February 2020 page 10 Cytogenomic Microarray Analysis for Neoplasia For the 2020 Current Procedural Terminology (CPT®) code set, a new Tier 1 molecular pathology procedure code (81277) is available to report genome-wide (cytogenomic) microarray analysis for neoplasia. Prior to 2020, cytogenomic microarray analysis was included as part of Tier 2 code 81406; however, the test has sufficiently increased in utilization to support conversion to Tier 1 status. This article provides an overview of these changes.

Article Overview
This article explains a February 2020 CPT update involving cytogenomic microarray analysis for neoplasia. It is aimed at coding professionals, laboratory staff, and clinicians who need to understand the scope of the code-set changes, the relationship between Tier 1 and Tier 2 molecular pathology procedures, and the general clinical context of the service.
Why This Topic Matters
It matters because CPT code-set updates can change how genomic laboratory services are reported and understood across pathology, laboratory medicine, oncology, and revenue cycle workflows.
