Deep endometriosis of the posterior cul-de-sac

This code signifies the presence of endometrial-like tissue deeply infiltrating the posterior cul-de-sac, also known as the pouch of Douglas. This condition is characterized by the growth of endometrial glands and stroma beyond the superficial peritoneal surface, causing significant inflammation and often severe pelvic pain. It represents a specific anatomical location and depth of endometriosis.

Utilize this code when documentation explicitly states deep infiltrating endometriosis affecting the posterior cul-de-sac. This diagnosis is typically confirmed through surgical visualization (laparoscopy or laparotomy) with or without histological confirmation of deeply infiltrating endometrial implants in this specific anatomical region. Documentation should clearly indicate the depth of infiltration beyond the superficial peritoneum.

• Differentiate from superficial peritoneal endometriosis of the cul-de-sac; this code specifically indicates deep infiltration.
• Ensure the documentation specifies "posterior cul-de-sac" or "pouch of Douglas" for accurate anatomical coding.
• Consider sequencing this code with codes for associated symptoms (e.g., chronic pelvic pain, dyspareunia) or complications (e.g., adhesions).
