AMA CPT handbooks for CY2018 are out, and one change in molecular coding is a revision of the code for BRCA gene panel testing (hereditary cancer gene panels).
The new code reflects a shortening of the required-genes list. This revision was classed as an editorial change and therefore did not trigger any action in the CMS crosswalk/gapfill process this fall.
The new code will be
Hereditary breast cancer-related disorders
(E.g. hereditary breast cancer, hereditary ovarian cancer, hereditary endometrial cancer)
Must including sequencing of at least 10 genes.
CHD1, MLH1, MSH2, MSH6, PALB2, PTEN, STK11, TP53.
Prior to January 2018, the gene list used to include:
ATM, BRIP1, NBN, RAD51C.
