Endometriosis of intestine

This code represents the presence of endometrial tissue abnormally located within the walls of the intestine. This ectopic tissue can cause symptoms such as abdominal pain, bleeding, and bowel dysfunction, often correlating with the menstrual cycle. It is a manifestation of endometriosis affecting the gastrointestinal tract.

Use this code when documentation explicitly states a diagnosis of endometriosis involving any part of the intestine. This diagnosis is typically confirmed through imaging studies, colonoscopy with biopsy, or surgical findings. It should be applied when the intestinal involvement is the primary focus or a significant co-morbidity.

• Ensure documentation specifies "intestine" rather than a general diagnosis of endometriosis without site specificity.
• Consider sequencing this code after a more generalized endometriosis code (e.g., 617.9) if the intestinal involvement is a secondary manifestation.
• Look for associated symptoms like bowel obstruction, rectal bleeding, or abdominal pain to support the diagnosis.
