The laboratory performs a familial hypercholesterolemia panel on peripheral blood/serum and the panel tests for genes APOB, LDLR, LDLRAP1, and PCSK9 for a total of four genes. Because there is no current genomic sequencing panel code for this panel and the LDLR gene is responsible for greater than 50% of pathogenic variants causing familial hypercholesterolemia, may code 81406 be reported for this test? If not, what code(s) should be reported for this test? ...

Article Overview
This coding guidance article addresses CPT reporting for a familial hypercholesterolemia panel and discusses how to classify the test within molecular pathology coding. It is useful for laboratory coders, billing staff, and compliance teams who need to understand how panel components are matched to CPT molecular pathology categories and how unlisted services are handled when a panel includes genes not specifically named in a code descriptor.
Why This Topic Matters
Accurate CPT reporting for molecular panels affects claim submission, documentation support, and compliance when a test includes multiple gene targets that do not all fit the same listed code.
