Calculus in diverticulum of bladder

This code signifies the presence of a stone (calculus) within an abnormal pouch or sac (diverticulum) that has formed in the wall of the urinary bladder. This condition can lead to urinary obstruction, infection, and pain.

Apply this code when documentation explicitly states a bladder calculus is located within a diverticulum. Supporting documentation would include imaging reports (e.g., ultrasound, CT scan) or cystoscopy findings confirming both the diverticulum and the calculus within it.

• Differentiate from bladder calculus not specified as being in a diverticulum.
• Do not use if the calculus is in the ureter or kidney; those have separate codes.
• Consider additional codes for associated conditions like urinary tract infection or obstruction.
