Deep endometriosis of the anterior cul-de-sac

This code signifies the presence of endometrial-like tissue deeply infiltrating the anterior cul-de-sac, also known as the vesicouterine pouch. This condition involves lesions extending more than 5mm beneath the peritoneal surface or into the muscularis of adjacent organs. It is a severe form of endometriosis affecting the space between the uterus and the bladder.

Apply this code when documentation explicitly states deep endometriosis involving the anterior cul-de-sac. This diagnosis is typically confirmed through imaging (e.g., MRI, transvaginal ultrasound) or surgical visualization and biopsy. Look for terms like "deep infiltrating endometriosis," "anterior cul-de-sac involvement," or "vesicouterine pouch endometriosis" with evidence of deep infiltration.

• Differentiate from superficial peritoneal endometriosis of the anterior cul-de-sac, which would be coded differently.
• Ensure documentation specifies "deep" involvement; otherwise, a less specific code for endometriosis of the anterior cul-de-sac might be more appropriate.
• Code any associated complications or symptoms, such as chronic pelvic pain or bladder dysfunction, as additional diagnoses.
