NTRK Gene Fusion Test on Tumor Tissue

Washington, DC rates for HCPCS 81191

A laboratory test performed on a sample of tumor tissue that looks for a rearrangement in which an NTRK gene has become joined to a different gene, creating an abnormal growth signal. Tumors carrying this change often respond to drugs designed specifically to block it, so the result helps choose treatment. The change arises inside the tumor and is not inherited from a parent.
