C56.3 Malignant neoplasm of bilateral ovaries

Name of the Condition

• Malignant neoplasm of bilateral ovaries
• Ovarian cancer, involving both ovaries

Summary

Malignant neoplasm of bilateral ovaries is a cancerous growth originating in both ovaries. It involves abnormal cell proliferation that may invade nearby tissues or spread to distant sites if untreated. Ovarian cancer is often diagnosed at advanced stages due to subtle early symptoms.

Causes

The exact cause of ovarian cancer is not fully understood, but it is associated with genetic mutations, such as BRCA1 and BRCA2, and alterations in cell growth regulation. Other contributing factors may include hormonal imbalances and environmental influences, though specific triggers remain under investigation.

Risk Factors

• Age: Most common in women over 50
• Family history: Having close relatives with ovarian, breast, or colorectal cancer
• Genetic mutations: BRCA1, BRCA2, or Lynch syndrome
• Reproductive history: Nulliparity or late first pregnancy
• Hormonal factors: Long-term estrogen exposure without progesterone
• Obesity: Higher body mass index (BMI)
• Endometriosis: Chronic uterine lining tissue outside the uterus

Symptoms

• Abdominal or pelvic pain, bloating, or pressure
• Persistent changes in bowel or bladder habits
• Unexplained weight loss or loss of appetite
• Fatigue or feeling full quickly
• Abnormal vaginal bleeding or discharge

Diagnosis

Diagnosis typically involves a combination of pelvic examination, imaging tests (e.g., ultrasound or CT scans), blood tests (including CA-125 marker), and biopsy to confirm cancerous cells. Additional tests may assess the extent of spread.

Treatment Options

Treatment may include surgery to remove the ovaries, fallopian tubes, or surrounding tissues, followed by chemotherapy or targeted therapy. The approach depends on the cancer stage and patient health.

Prognosis and Follow-Up

Prognosis varies based on stage at diagnosis, tumor type, and response to treatment. Regular follow-up with imaging, blood tests, and physical exams is essential to monitor for recurrence or complications.

Complications

Complications may include bowel obstruction, ascites (fluid buildup), metastasis to other organs, or treatment-related side effects like infection or organ damage.

Lifestyle & Prevention

While no guaranteed prevention exists, maintaining a healthy weight, discussing hormonal therapy risks with a provider, and considering genetic counseling for high-risk individuals may help reduce risk.

When to Seek Professional Help

Seek medical attention for persistent abdominal pain, bloating, or unexplained weight loss, especially if symptoms worsen or interfere with daily activities.

Tips for Medical Coders

Use C56.3 for malignant neoplasm of bilateral ovaries. Ensure documentation specifies bilateral involvement to support code assignment. Verify no other site-specific codes apply if ovaries are the primary focus.
