Endometriosis of the anterior cul-de-sac, unspecified depth

This code signifies the presence of endometrial-like tissue located in the anterior cul-de-sac (vesicouterine pouch), a peritoneal space between the uterus and the bladder. This condition is characterized by the growth of this tissue outside the uterus, leading to inflammation and potential pain. The "unspecified depth" indicates that the extent of tissue infiltration into the surrounding structures is not documented.

Use this code when documentation confirms endometriosis specifically located in the anterior cul-de-sac, but the depth of invasion (e.g., superficial, deep) is not specified by the provider. This diagnosis is typically made through imaging studies (e.g., ultrasound, MRI) or surgical visualization during laparoscopy.

• Ensure the documentation explicitly states "anterior cul-de-sac" and does not specify depth.
• If the depth is documented (e.g., superficial, deep), a more specific subcategory code should be used.
• Consider sequencing this code after any codes for associated symptoms (e.g., chronic pelvic pain, dyspareunia) or complications.
