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.
A clinician-ordered single gene or allele test is considered covered when the billed component corresponds to the single gene/allele that was reasonable and necessary, even if the laboratory platform concurrently interrogated other genes operationally.
Germline testing panels that include some previously tested genetic content may be covered if there is established clinical utility for the remaining non-duplicative genetic components of the panel.
Genes may be assayed serially or in parallel; additional gene analyses done after a reflex decision are covered when those reflexive analyses are reasonable and necessary for the beneficiary's care.
