Superficial endometriosis of the small intestine

This code signifies the presence of endometrial tissue abnormally located on the outer surface or within the superficial layers of the small intestine. This ectopic tissue, while benign, responds to hormonal fluctuations, potentially causing inflammation, pain, and gastrointestinal symptoms. It represents a specific manifestation of endometriosis affecting a particular segment of the digestive tract.

Apply this code when documentation explicitly states superficial endometriosis involving the small intestine. This diagnosis is typically confirmed through surgical visualization (e.g., laparoscopy) with or without biopsy. Supporting documentation should clearly indicate the anatomical site and depth of involvement.

• Differentiate from deep infiltrating endometriosis of the small intestine, which has a distinct code.
• Code any associated complications, such as intestinal obstruction or adhesions, separately.
• Ensure the documentation specifies "superficial" to accurately assign this code.
