N83.10 Corpus luteum cyst of ovary, unspecified side

Name of the Condition

• Corpus luteum cyst of ovary, unspecified side

Summary

Corpus luteum cysts are fluid-filled sacs that develop on the ovary after ovulation. They form when the corpus luteum, a temporary hormone-secreting structure, seals and accumulates fluid. These cysts are typically benign and may resolve without treatment.

Causes

The exact cause is not fully understood, but hormonal imbalances during the menstrual cycle can contribute to their development. They occur when the corpus luteum fails to break down as expected after ovulation.

Risk Factors

• Being of reproductive age
• Irregular menstrual cycles
• History of ovarian cysts
• Undergoing fertility treatment

Symptoms

• Abdominal or pelvic pain
• Bloating
• Menstrual irregularities
• In some cases, no symptoms are present

Diagnosis

Pelvic examination to assess for tenderness or swelling. Ultrasound imaging to visualize the cyst. Blood tests may be used to rule out other conditions or assess hormone levels.

Treatment Options

• Observation and follow-up ultrasounds for small, asymptomatic cysts
• Pain management with over-the-counter medications if needed
• Hormonal contraceptives to regulate cycles and prevent recurrence
• Surgery (e.g., laparoscopy) for large or symptomatic cysts

Prognosis and Follow-Up

Most corpus luteum cysts resolve on their own within a few menstrual cycles. Follow-up monitoring may be recommended to ensure the cyst does not persist or grow.

Complications

• Rupture of the cyst, causing sudden pain
• Ovarian torsion (twisting of the ovary)
• Infection (rare)

Lifestyle & Prevention

• Maintain regular menstrual cycle patterns through healthy lifestyle habits
• Avoid unnecessary hormonal disruptions
• Discuss fertility treatments with a healthcare provider to minimize cyst risk

When to Seek Professional Help

Seek care if experiencing severe pelvic pain, fever, or signs of rupture (e.g., sudden sharp pain, dizziness). Persistent or worsening symptoms should also prompt evaluation.

Tips for Medical Coders

Document the side of the ovary (left, right, or unspecified) when available. For N83.10, use this code when the side is not specified. Ensure documentation supports the diagnosis and aligns with clinical findings.
