Endometriosis of rectovaginal septum and vagina

This code represents the presence of endometrial tissue outside the uterus, specifically affecting the rectovaginal septum and/or the vaginal wall. This ectopic tissue responds to hormonal changes, leading to inflammation, pain, and potential scarring in these areas.

Use this code when documentation clearly indicates endometriosis involving the rectovaginal septum or the vagina, often diagnosed via imaging, biopsy, or direct visualization during surgery. It is appropriate for patients presenting with deep dyspareunia, rectal pain, or vaginal bleeding associated with menses, where the pathology is confirmed to be in these specific locations.

• Ensure documentation specifies involvement of the rectovaginal septum or vagina; general pelvic endometriosis is coded elsewhere.
• Consider sequencing with codes for associated symptoms (e.g., dyspareunia, chronic pelvic pain) if they are not integral to the endometriosis diagnosis.
• Distinguish from adenomyosis, which involves endometrial tissue within the myometrium.
