Malignant neoplasm of left ovary

This code signifies a cancerous tumor originating in the left ovary. It indicates a primary malignancy, meaning the cancer began in the ovary itself rather than spreading from another site. This condition can lead to various symptoms including pelvic pain, abdominal distension, and changes in bowel or bladder habits.

Utilize this code when documentation clearly states a primary malignant neoplasm of the left ovary. This diagnosis is typically confirmed through biopsy and imaging studies. It should be applied when the laterality of the ovarian cancer is specifically identified as left.

• Ensure documentation specifies "left ovary" and "malignant" to avoid miscoding.
• Do not use this code for secondary (metastatic) ovarian cancer; instead, code the primary site and then the secondary site.
• Consider additional codes for specific histological types (e.g., serous adenocarcinoma) or for any associated complications or symptoms.
