Pharmacogenomics (PGx) testing is covered when it is reasonable and necessary per LCD L39063 and Medicare coverage rules for the beneficiary's clinical indication.
CPT 81418 (PGx multi-gene panel) is covered when the test assays at least 6 genes, including CYP2C19 and CYP2D6 and CYP2D6 duplication/deletion analysis, and the panel is clinically indicated to guide drug therapy.
