Needle Muscle Test of Half the Diaphragm

Washington rates for HCPCS 95866

This test inserts a thin needle electrode into the diaphragm muscle on one side to record its electrical activity directly, evaluating how well the nerve and muscle controlling that side of breathing are working. It is used to investigate unexplained breathing difficulty or suspected weakness of the diaphragm when other tests have not clarified the cause. The recording is typically done with imaging guidance to safely place the needle near the lung and chest structures.
