Malignant neoplasm of right round ligament

This code signifies a primary cancerous tumor originating in the right round ligament of the uterus. This is a rare gynecological malignancy affecting the fibrous cord that extends from the uterus to the labia majora.

Use this code when documentation explicitly states a malignant neoplasm of the right round ligament. This diagnosis is typically confirmed through biopsy and histopathological examination. Supporting documentation would include pathology reports and physician notes detailing the tumor's location and malignant nature.

• Ensure the laterality (right) is clearly documented. If the laterality is unspecified, a different code would be required.
• Distinguish from benign tumors of the round ligament, which would be coded differently.
• Always sequence this code according to the primary site rules for neoplasms, typically as the primary diagnosis if it's the reason for the encounter.
