Endometriosis of rectovaginal septum, unsp invl of vagina

This code represents the presence of endometrial tissue abnormally located in the rectovaginal septum, a fibrous tissue separating the rectum and vagina. The "unspecified involvement of vagina" indicates that while the rectovaginal septum is affected, the specific extent or nature of vaginal involvement is not documented. This condition can cause significant pelvic pain, dyspareunia, and bowel symptoms.

Use this code when documentation confirms endometriosis specifically located within the rectovaginal septum, but the medical record does not specify whether the endometriosis also involves the vaginal wall directly or the specific type of vaginal involvement. This code is appropriate when the provider's diagnosis explicitly states "endometriosis of rectovaginal septum" without further detail regarding vaginal extension.

• Do not use this code if the documentation specifies involvement of the vaginal wall (e.g., N80.41-N80.49).
• Always seek clarification from the provider if the documentation is ambiguous regarding specific vaginal involvement.
• Consider sequencing this code with codes for associated symptoms (e.g., chronic pelvic pain, dyspareunia) if documented.
