Endometriosis of the abdomen, unspecified

This code signifies the presence of endometrial tissue outside the uterus, specifically within the abdominal cavity, without further specification of the exact location. This condition can lead to chronic pelvic pain, dysmenorrhea, dyspareunia, and infertility.

Use this code when documentation confirms endometriosis located within the abdomen, but the specific anatomical site (e.g., peritoneum, bowel, diaphragm) is not identified. This code is appropriate when the physician's assessment indicates abdominal involvement without further granular detail.

• Avoid using this code if a more specific anatomical site of abdominal endometriosis is documented (e.g., N80.A1 for endometriosis of the rectovaginal septum).
• Ensure the documentation clearly states "abdomen" or "abdominal cavity" to support this code.
• Sequence this code as a primary diagnosis when it is the reason for the encounter, or as a secondary diagnosis when it is a co-morbidity affecting treatment.
