Clinical & Coding Specifications
Clinical Context
A patient presents to the outpatient hospital with symptoms such as flank pain, hematuria, or urinary obstruction. Imaging studies confirm the presence of a urinary calculus, such as a kidney stone or ureteral stone. The urology physician determines that extracorporeal shock wave lithotripsy is appropriate for stone fragmentation. The procedure is performed in the outpatient setting, with the patient under sedation or anesthesia. The care team may include a urology physician, surgical oncology physician, or radiation oncology physician, depending on the complexity. Post-procedure, the patient is monitored for stone passage and potential complications.
