Calculus of ureter

This code signifies the presence of a stone (calculus) within the ureter, the tube that carries urine from the kidney to the bladder. These stones can cause significant pain, obstruction, and potential damage to the urinary tract.

This code is appropriate when documentation clearly indicates a ureteral calculus, often presenting with symptoms like renal colic, hematuria, or hydronephrosis. Supporting documentation includes imaging reports (e.g., CT scan, ultrasound, KUB) confirming the stone's location in the ureter, or operative reports detailing its removal.

• Differentiate from renal calculus (nephrolithiasis); the location is key.
• Consider additional codes for associated conditions like hydronephrosis (591) or urinary tract infection (599.0).
• Ensure the documentation specifies the ureter as the stone's location to avoid miscoding as kidney stone.
