Malignant neoplasm of left round ligament

This diagnosis code signifies the presence of a cancerous tumor originating in the left round ligament of the uterus. This is a primary malignancy, meaning the cancer started in this specific anatomical location rather than spreading there from another site.

This code is appropriate when documentation clearly states a primary malignant neoplasm affecting the left round ligament. It should be used when pathology reports confirm malignancy and specify the left side.

• Ensure laterality is explicitly documented as "left" to support this specific code.
• Distinguish from secondary malignancies or benign neoplasms of the round ligament.
• Sequence according to the primary site rules for oncology coding, often as the primary diagnosis.
