Kaposi's sarcoma, gastrointestinal sites

This code identifies Kaposi's sarcoma specifically affecting organs within the gastrointestinal tract. This malignant vascular tumor, often associated with HIV/AIDS, can manifest in the esophagus, stomach, intestines, or other digestive organs.

Use this code when documentation confirms a diagnosis of Kaposi's sarcoma with primary or metastatic involvement of any gastrointestinal site. This includes findings from endoscopy, biopsy, or imaging studies indicating lesions in the GI tract.

• Always confirm the specific site of Kaposi's sarcoma; do not use for cutaneous or pulmonary involvement.
• Code any associated HIV infection (042) as a secondary diagnosis when applicable.
• Distinguish from other gastrointestinal neoplasms; ensure pathology reports confirm Kaposi's sarcoma.
