Gene Test Guiding Chemotherapy Dosing

Arizona rates for HCPCS 81346

A laboratory test that examines one particular gene in a blood sample for specific known variations that change how the body handles a chemotherapy medicine. People carrying certain versions clear the medicine faster or slower than usual, which alters how much benefit and how much side effect a standard dose produces. The result helps the treating team set the dose or choose between medicines; it is not used to diagnose a condition.
