M71.311 Other bursal cyst, right shoulder

Name of the Condition

• Other bursal cyst, right shoulder

Summary

An other bursal cyst in the right shoulder is a fluid-filled sac that forms in or around a bursa, a small lubricating structure that reduces friction between tissues. These cysts are non-cancerous and typically result from irritation, inflammation, or structural changes in the bursa, leading to localized swelling or discomfort in the shoulder area.

Causes

Other bursal cysts can develop due to repetitive motion, direct trauma, or underlying inflammatory conditions affecting the bursa. They may also arise from degenerative processes or mechanical stress on the bursal tissue in the shoulder.

Risk Factors

• Repetitive or prolonged pressure on shoulder bursae (e.g., from overhead activities)
• Occupational or athletic activities involving repetitive shoulder use
• Pre-existing inflammatory conditions (e.g., arthritis)
• Recent injury or surgery near the shoulder bursa
• Age-related degenerative changes

Symptoms

• Swelling or a visible lump at the right shoulder
• Pain or tenderness, especially with movement or pressure
• Limited range of motion in the shoulder
• Discomfort or stiffness in the area

Diagnosis

Diagnosis typically involves a physical examination to assess cyst characteristics, along with imaging (e.g., ultrasound or MRI) to evaluate tissue changes. Fluid aspiration may be performed if diagnosis is uncertain.

Treatment Options

• Observation for cysts causing no significant symptoms
• Aspiration to drain the fluid and reduce swelling
• Corticosteroid injections to reduce inflammation
• Physical therapy to improve mobility and reduce stress on the bursa
• Surgical removal for persistent, painful, or recurrent cysts

Prognosis and Follow-Up

Most other bursal cysts resolve with conservative treatment, though recurrence is possible. Follow-up may involve monitoring for symptom changes or repeat imaging if symptoms persist. Long-term outcomes are generally favorable with appropriate management.

Complications

• Recurrence of the cyst
• Persistent pain or limited mobility if untreated
• Infection if the cyst is aspirated or drained
• Nerve compression in rare cases

Lifestyle & Prevention

• Avoid repetitive overhead movements or modify activities to reduce shoulder stress
• Use proper ergonomic techniques during work or sports
• Apply ice to the shoulder after activity to reduce inflammation
• Maintain shoulder strength and flexibility through exercise

When to Seek Professional Help

Seek medical attention if the cyst causes severe pain, limits movement, grows rapidly, or shows signs of infection (e.g., redness, warmth, fever). Prompt evaluation is recommended for persistent or worsening symptoms.

Tips for Medical Coders

Document the specific location (right shoulder) and any associated details, such as trauma or underlying conditions, to support accurate coding. Ensure the diagnosis aligns with clinical findings and imaging results. Note that this code is specific to the right shoulder; location must be clearly documented for correct assignment.
