Urethral false passage

This code describes an iatrogenic injury to the urethra where a new, abnormal channel or tract is created alongside the true urethral lumen. This typically occurs during instrumentation of the urinary tract, such as catheterization, cystoscopy, or other urological procedures. It represents a deviation from the normal anatomical pathway.

Use this code when documentation clearly indicates the formation of a false passage within the urethra, often as a complication of a medical procedure. This diagnosis is supported by operative reports, procedure notes, or imaging studies (e.g., urethrography) that identify the abnormal tract. It signifies a procedural complication rather than a pre-existing anatomical anomaly.

• Ensure documentation specifies "false passage" and not just a difficult or traumatic catheterization without actual tract creation.
• Always sequence this code after the primary reason for the encounter or the procedure that led to the complication.
• Consider additional codes for any associated complications, such as hemorrhage (e.g., N36.8) or infection (e.g., N39.0).
