M71.55 Other bursitis, not elsewhere classified, hip

Name of the Condition

• Other bursitis, not elsewhere classified, hip

Summary

Other bursitis, not elsewhere classified, hip refers to inflammatory conditions affecting the bursae (small fluid-filled sacs that reduce friction between tissues) around the hip that do not fall under more specific bursitis codes. These conditions may involve bursal irritation, swelling, or structural changes, leading to localized pain or functional impairment in the hip region.

Causes

Other bursitis of the hip can result from direct trauma, repetitive motion, infection, or systemic inflammatory conditions. They may also arise from metabolic or degenerative processes affecting the bursa, though the exact etiology varies by case.

Risk Factors

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

Symptoms

• Localized pain or tenderness over the affected hip bursa
• Swelling or visible lump at the site
• Reduced range of motion in the hip
• Discomfort with movement or pressure
• Possible warmth or redness if inflamed

Diagnosis

Diagnosis typically involves a physical examination to assess bursal characteristics, along with imaging (e.g., ultrasound, MRI) to evaluate tissue changes. Fluid aspiration and analysis may be performed if infection or crystal-induced inflammation is suspected.

Treatment Options

Treatment may include rest, activity modification, and nonsteroidal anti-inflammatory drugs (NSAIDs) to reduce pain and inflammation. Physical therapy can help improve mobility and strength. Corticosteroid injections may be used for persistent symptoms. In severe or refractory cases, surgical intervention may be considered.

Prognosis and Follow-Up

Most cases of hip bursitis improve with conservative management, though recovery time varies. Follow-up care may involve monitoring symptoms and adjusting treatment as needed. Recurrence is possible, particularly with ongoing risk factors or inadequate management.

Complications

Potential complications include chronic pain, limited mobility, or infection if the bursa becomes inflamed or ruptured. Untreated or severe cases may lead to functional impairment or the development of calcific deposits.

Lifestyle & Prevention

• Avoid prolonged pressure on the hip (e.g., use cushioned seating)
• Engage in regular low-impact exercise to maintain hip strength and flexibility
• Use proper form during activities to reduce repetitive stress
• Manage underlying inflammatory conditions as directed by a healthcare provider

When to Seek Professional Help

Seek medical attention if symptoms worsen, persist despite home care, or are accompanied by fever, significant swelling, or inability to bear weight. Prompt evaluation is important if infection or severe inflammation is suspected.

Tips for Medical Coders

Document the specific location (hip) and clinical findings to support the use of M71.55. Ensure the diagnosis aligns with the criteria for "other bursitis, not elsewhere classified" and that more specific codes are not applicable. Include details on symptom duration, imaging results, or treatment responses when available to support medical necessity.
