Superficial endometriosis of right ureter

This code signifies the presence of endometrial-like tissue growing on the surface of the right ureter. This ectopic tissue can cause inflammation, scarring, and potentially obstruct the ureter, leading to hydronephrosis or renal dysfunction. It represents a specific anatomical location for superficial endometriosis.

Apply this code when documentation clearly indicates superficial endometriosis affecting the right ureter, typically identified during surgical exploration (e.g., laparoscopy) or imaging studies. Supporting documentation should specify both the laterality (right) and the superficial nature of the endometrial implants on the ureter.

• Ensure documentation specifies "superficial" involvement; deep infiltrating endometriosis of the ureter would be coded differently.
• Always confirm laterality (right vs. left vs. bilateral) as separate codes exist.
• Consider co-reporting with codes for any associated complications, such as hydronephrosis (N13.x) if present.
