Spinocerebellar Ataxia: Gene-analysis Evaluation (September 2019)
September 2019 pages 7-8 Spinocerebellar Ataxia: Gene-analysis Evaluation For 2019, new molecular pathology codes (81178-81183) were created to describe genetic analysis and evaluation to detect the presence of specific genes associated with spinocerebellar ataxia (SCA). Before 2019, this genetic testing was reported with Tier 2 code 81401, Molecular pathology procedure, Level 2 (eg, 2-10 SNPs, 1 methylated variant, or 1 somatic variant [typically using nonsequencing target variant analysis], or detection of a dynamic mutation disorder/triplet repeat), which included genes associated with SCA but did not specify an SCA gene. Because this type of genetic analysis has increased in usage...

Article Overview
This article explains a 2019 CPT update focused on molecular pathology testing for spinocerebellar ataxia. It outlines the new gene-specific Tier 1 codes, contrasts them with prior reporting approaches, and presents clinical examples and procedural descriptions intended for coders and laboratory professionals working with hereditary neurologic testing.
Why This Topic Matters
It helps readers understand a notable molecular pathology coding update for hereditary ataxia testing and identify which article applies to gene-specific SCA testing workflows and reporting.
