Malignant neoplasm of right ureter

This code signifies a primary cancerous tumor originating in the right ureter. It indicates the presence of malignant cells within the wall or lumen of the tube that carries urine from the right kidney to the bladder. This is a life-threatening condition requiring prompt medical intervention.

Use this code when documentation clearly states a primary malignant neoplasm located specifically in the right ureter. This diagnosis is typically supported by pathology reports confirming malignancy and imaging studies (e.g., CT scan, MRI) localizing the tumor to the right ureter.

• Ensure the laterality is explicitly documented as "right" to avoid using an unspecified or left-sided code.
• Distinguish from secondary malignancies or metastatic disease to the ureter; this code is for primary cancer.
• Sequence this code as the primary diagnosis when it is the reason for the encounter, followed by any associated signs, symptoms, or complications.
