Breast Tumor Gene Test For Longer Hormone Therapy

Montana rates for HCPCS 81518

A laboratory test run on breast tumor tissue that measures how active a set of genes is and turns the readings into a score. The score estimates the chance of the cancer returning in later years and how likely it is that continuing hormone-blocking treatment beyond the usual course would help. It uses tissue already removed at biopsy or surgery, so no new procedure is needed.
