Malignant neoplasm of right ovary

This code signifies the presence of a cancerous tumor originating in the right ovary. It indicates a primary malignancy, meaning the cancer began in the ovary itself rather than spreading from another site. This diagnosis often involves abnormal cell growth with the potential to invade surrounding tissues or metastasize.

Use this code when documentation explicitly states a primary malignant neoplasm of the right ovary. This is appropriate for initial diagnoses, treatment, and follow-up care for ovarian cancer specifically affecting the right side. Supporting documentation includes pathology reports confirming malignancy and laterality, as well as physician notes detailing the diagnosis.

• Always confirm laterality (right vs. left) from the physician's documentation or pathology report.
• Do not use this code for secondary metastatic cancer to the ovary; use a secondary malignancy code with the appropriate primary site.
• Consider additional codes for the specific histological type of ovarian cancer (e.g., serous, endometrioid) if documented, as well as any associated symptoms or complications.
