"CPT codes 50080 and 50081 describe the antegrade approach to stone removal requiring lithotripsy through a nephrostomy tract, with 50080 being reported for stones less than 2 cm in size in a single location, whereas 50081 would be reported for large or complex stones, stones in multiple locations, or stones in the ureter (such as in the example provided)," write Jonathan Rubenstein, MD, and Mark Painter.
