Name of the Condition

• Common Name: Ganglion Cysts
• Technical Term: Ganglion, multiple sites (ICD-10 Code: M67.49)

Summary

Ganglion cysts are non-cancerous lumps that typically develop along the tendons or joints of your wrists or hands. They are filled with a jelly-like fluid and can vary in size. In some cases, they may occur at multiple sites on the body.

Causes

The exact cause of ganglion cysts is unknown. They may arise from joint or tendon irritation or injury, which could contribute to their development.

Risk Factors

• Age: Most common in people aged 20-40.
• Gender: Women are more likely to develop ganglion cysts.
• Joint or tendon injury: Previous injuries may increase risk.
• Activities: Repetitive wrist or hand movements can contribute to cyst formation.

Symptoms

• Visible lump or swelling, often round or oval
• Pain or discomfort if the cyst presses on a nerve
• Tingling, weakness, or numbness in the affected area

Diagnosis

• Physical Examination: Visual and tactile inspection by a healthcare provider.
• Imaging Tests: Ultrasound or MRI to assess the cyst's structure and location.
• Aspiration: Fluid may be drawn from the cyst for analysis.

Treatment Options

• Observation: In some cases, ganglion cysts resolve on their own.
• Aspiration: Draining the fluid, although cysts can recur.
• Surgery: Removal may be considered if cysts are painful or interfere with function.

Prognosis and Follow-Up

• Prognosis is generally good; many cysts resolve without intervention.
• Regular follow-up may be necessary to monitor for recurrence or complications.

Complications

• Persistent pain or discomfort
• Limited mobility if located near joints
• Recurrence, even after treatment

Lifestyle & Prevention

• Avoid repetitive wrist and hand movements to reduce stress on joints.
• Use protective gear during sports or activities that stress the wrist.

When to Seek Professional Help

• Sudden increase in size or changes in appearance
• Severe pain, redness, or warmth around the cyst
• Numbness, tingling, or weakness in the hand or fingers

Tips for Medical Coders

• Ensure correct coding by confirming multi-site ganglion cysts.
• Cross-reference any related procedures, such as aspiration or surgical removal, for accuracy.
• Be mindful of reporting location specifics to enhance documentation precision.
