PIK3CA Testing On A Blood Plasma Sample

Washington, DC rates for HCPCS 0177U

A breast cancer test that examines plasma, the liquid part of a blood sample, for 11 specific changes in the PIK3CA gene. The result states whether any of those changes were found. Because the test works from a blood draw, no tumor tissue has to be removed; a companion version looks for the same 11 changes in tumor tissue.
