N83.02 Follicular cyst of left ovary

Name of the Condition

• Follicular cyst of left ovary

Summary

Follicular cyst of the left ovary is a benign, fluid-filled sac that forms on the ovary when a follicle (the structure containing an egg) fails to rupture and release the egg during ovulation. Instead, the follicle continues to grow, resulting in a cyst. These cysts are common and often resolve without intervention.

Causes

These cysts develop due to hormonal imbalances that disrupt the normal ovulation process, preventing the follicle from rupturing and leading to its persistence and enlargement.

Risk Factors

• Hormonal imbalances
• Irregular menstrual cycles
• Previous ovarian cysts
• Certain fertility treatments

Symptoms

• Often asymptomatic
• Abdominal bloating or swelling
• Pelvic pain or discomfort
• Changes in menstrual cycle consistency

Diagnosis

Pelvic examination to assess for tenderness or masses. Ultrasound imaging to visualize the cyst and determine its size and characteristics. Sometimes, MRI scans to differentiate from other conditions.

Treatment Options

• Observation, as many cysts resolve spontaneously
• Birth control pills to regulate menstrual cycles and prevent future cysts
• Surgery, such as laparoscopy, may be needed if cysts are large, persistent, or cause severe symptoms

Prognosis and Follow-Up

Most follicular cysts resolve on their own without treatment. Regular follow-up with ultrasound imaging can monitor cyst size and resolution.

Complications

• Rarely, complications such as cyst rupture or ovarian torsion can occur, leading to severe pain and potential emergency situations.

Lifestyle & Prevention

• Maintaining regular menstrual cycles through hormonal balance may reduce risk.
• Avoiding unnecessary hormonal treatments unless medically indicated.

When to Seek Professional Help

• Persistent pelvic pain or discomfort
• Sudden, severe abdominal pain (possible rupture or torsion)
• Changes in menstrual patterns or abnormal bleeding

Tips for Medical Coders

• Use code N83.02 for follicular cysts specifically located in the left ovary.
• Ensure documentation specifies the cyst's location (left ovary) and confirms it is a follicular cyst to support accurate coding.
• Differentiate from other ovarian cyst types (e.g., corpus luteum) based on clinical findings and imaging.
