M71.35 Other bursal cyst, hip

Name of the Condition

• Other bursal cyst, hip

Summary

An other bursal cyst in the hip 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 hip region.

Causes

Other bursal cysts in the hip 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.

Risk Factors

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

Symptoms

• Swelling or a visible lump at the affected hip site
• Pain or tenderness, especially with movement or pressure
• Limited range of motion in the hip
• 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 symptoms
• Rest and activity modification to reduce irritation
• Nonsteroidal anti-inflammatory drugs (NSAIDs) for pain and inflammation
• Physical therapy to improve mobility and strength
• Corticosteroid injections to reduce inflammation
• Surgical removal if cysts are persistent or symptomatic

Prognosis and Follow-Up

Most other bursal cysts in the hip resolve with conservative treatment, though recurrence is possible. Follow-up may involve monitoring symptoms and imaging if needed. Surgical outcomes are generally favorable, with most patients experiencing symptom relief.

Complications

• Persistent pain or discomfort
• Limited mobility or functional impairment
• Infection if the cyst is aspirated or drained
• Recurrence after treatment

Lifestyle & Prevention

• Avoid repetitive hip movements or prolonged pressure
• Maintain a healthy weight to reduce joint stress
• Use proper form during physical activities
• Warm up before exercise to reduce injury risk
• Address underlying inflammatory conditions promptly

When to Seek Professional Help

Seek medical attention if you experience severe or worsening pain, sudden swelling, difficulty moving the hip, signs of infection (e.g., redness, fever), or if symptoms do not improve with rest or over-the-counter treatments.

Tips for Medical Coders

Document the specific location (hip) and any contributing factors (e.g., trauma, inflammation) to support code assignment. Ensure clinical documentation aligns with the diagnosis and includes details about cyst characteristics (e.g., size, symptoms) for accurate coding.
