Calculus in urethra

This code signifies the presence of a stone or calculus lodged within the urethra, the tube that carries urine from the bladder out of the body. These calculi can cause urinary obstruction, pain, and difficulty voiding.

Assign this code when documentation clearly indicates a urethral calculus, often presenting with symptoms like dysuria, hematuria, or acute urinary retention. This diagnosis is typically confirmed by imaging studies such as ultrasound, CT scan, or cystoscopy.

• Differentiate from calculi located in other parts of the urinary tract; this code is specific to the urethra.
• Do not use for prostatic calculi (N42.0), even if they are near the urethral opening.
• Consider sequencing with codes for associated symptoms (e.g., R30.0 for dysuria) or complications (e.g., N39.0 for urinary tract infection).
