Creating And Widening A Kidney Access Passage

California rates for HCPCS 50437

Creates a passage from the skin into the urine-collecting part of the kidney and then widens it, so instruments can be passed through to treat stones or other problems. Imaging guides the needle and the dilators, and a tube is often left in the passage at the end. Both the new passage and the widening are done in the same session.
