Kaposi's sarcoma of right lung

This code signifies a malignant neoplasm characterized by the abnormal growth of blood vessel cells, specifically affecting the right lung. Kaposi's sarcoma is often associated with human herpesvirus 8 (HHV-8) infection and is frequently seen in immunocompromised individuals.

Apply this code when documentation explicitly states a diagnosis of Kaposi's sarcoma located in the right lung. This is typically supported by pathology reports confirming the diagnosis and imaging studies (e.g., CT scan) localizing the lesion to the right lung.

• Always confirm the specific lung (right or left) and the histological type of sarcoma from the pathology report.
• Code an underlying immunocompromised state (e.g., HIV infection) as a secondary diagnosis, if applicable and documented.
• Do not confuse with other primary or secondary lung malignancies; ensure the documentation specifies Kaposi's sarcoma.
