C79.63 Secondary malignant neoplasm of bilateral ovaries

Name of the Condition

• Secondary Malignant Neoplasm of Bilateral Ovaries
• ICD-10 Code: C79.63

Summary

Secondary malignant neoplasm of bilateral ovaries refers to cancer that has metastasized to both ovaries from a primary tumor located elsewhere in the body. This condition indicates the spread of an existing malignancy to the ovarian tissue and requires evaluation to identify the primary cancer source and guide management.

Causes

Secondary malignant neoplasms of bilateral ovaries arise when cancer cells from a primary tumor detach, travel through the bloodstream or lymphatic system, and establish new tumors in both ovaries. Common primary sites include the breast, gastrointestinal tract, or other organs with high metastatic potential.

Risk Factors

• History of primary cancer, particularly those with known ovarian metastatic patterns (e.g., breast, colorectal).
• Advanced stage of the primary tumor.
• Lack of effective treatment for the primary cancer.
• Weakened immune system.
• Genetic predisposition to aggressive cancer types.

Symptoms

• Abdominal or pelvic pain.
• Bloating or swelling in the abdomen.
• Changes in bowel or urinary habits.
• Unexplained weight loss or fatigue.
• Vaginal bleeding (postmenopausal or irregular).
• Palpable abdominal mass.

Diagnosis

Imaging tests (CT, MRI, or PET scans) are used to detect metastatic lesions in both ovaries. Biopsy of ovarian tissue may be performed to confirm the diagnosis and identify the primary cancer source.

Treatment Options

Treatment focuses on managing the primary cancer and controlling metastatic disease. Options may include systemic therapies (chemotherapy, targeted therapy), hormonal therapy, or palliative care to relieve symptoms. The choice of treatment depends on the primary tumor type, extent of spread, and patient health.

Prognosis and Follow-Up

Prognosis varies based on the primary cancer type, extent of metastasis, and response to treatment. Regular follow-up with imaging and clinical evaluations is essential to monitor for disease progression or recurrence.

Complications

• Obstruction of the gastrointestinal or urinary tract.
• Ascites (fluid buildup in the abdomen).
• Pain or discomfort.
• Reduced quality of life due to advanced disease.

Lifestyle & Prevention

• Maintain a healthy lifestyle to support overall well-being during treatment.
• Follow recommended cancer screening guidelines for early detection of primary tumors.
• Discuss risk reduction strategies with a healthcare provider, especially if there is a history of cancer.

When to Seek Professional Help

Seek medical attention if you experience persistent abdominal pain, bloating, unexplained weight loss, or other symptoms of concern. Prompt evaluation is important for managing metastatic disease and addressing complications.

Tips for Medical Coders

Document the presence of bilateral ovarian involvement and confirm the primary cancer source when possible. Ensure the code C79.63 is used only when both ovaries are affected by secondary malignancy. Include details about diagnostic tests or biopsies to support the diagnosis in the medical record.
