Extravasation of urine

This code signifies the leakage of urine from its normal anatomical pathway, such as the bladder, ureter, or urethra, into surrounding tissues. This extravasation can result from trauma, surgical complications, or underlying pathological conditions causing a breach in the urinary tract.

Use this code when documentation clearly indicates urine leakage outside the urinary system. This often occurs post-trauma (e.g., bladder rupture), following urological procedures (e.g., ureteral injury during surgery), or due to obstructive uropathy leading to fornix rupture. Documentation should specify the presence of urine in extra-urinary spaces.

• Do not confuse with urinary incontinence (N39.3, N39.4-) which refers to involuntary urine leakage from the urethra.
• Always code the underlying cause of the extravasation first, if known and applicable (e.g., trauma, surgical complication).
• Specify the site of extravasation if further detail is available in the documentation, using additional codes if necessary (e.g., retroperitoneal fluid collection).
