Endometriosis of other site of abdomen

This code signifies the presence of endometrial tissue outside the uterus, specifically located within various abdominal sites other than the ovaries, fallopian tubes, uterus, uterosacral ligament, rectovaginal septum, intestine, or pelvic peritoneum. This ectopic tissue responds to hormonal changes, leading to inflammation, pain, and potential adhesions in these abdominal locations.

Apply this code when documentation specifies endometriosis affecting abdominal organs or structures not covered by more specific N80.x codes, such as the omentum, spleen, diaphragm, or abdominal wall. Supporting documentation should clearly identify the affected abdominal site and confirm the diagnosis of endometriosis.

• Ensure the documentation explicitly states an "other" abdominal site; avoid using this code for unspecified abdominal endometriosis.
• Distinguish from N80.A (Endometriosis of intestine) or N80.B (Endometriosis of pelvic peritoneum) if those sites are specifically documented.
• Code any associated pain or complications, such as chronic pelvic pain (R10.2) or infertility (N97.x), as secondary diagnoses.
