Kidney Stone Treatment (Lithotripsy - ESWL)
What is this procedure?
Extracorporeal shock wave lithotripsy (ESWL) where focused shock waves are directed at kidney stones from outside the body to break them into smaller fragments that can pass naturally. Used for renal and upper ureteral stones typically between 5mm and 20mm that have not passed spontaneously.
Does this require prior authorization?
