M71.159 Other infective bursitis, unspecified hip

Name of the Condition

• Other infective bursitis, unspecified hip

Summary

Other infective bursitis, unspecified hip refers to an infection of the bursa in the hip region that is not classified under more specific infective bursitis codes. This condition involves microbial invasion of the bursa, leading to inflammation, pain, and potential functional impairment of the hip joint.

Causes

Other infective bursitis, unspecified hip typically results from bacterial infection, often introduced through direct trauma, skin breakdown, or spread from adjacent tissues. Common causative organisms include Staphylococcus aureus. Non-bacterial infections or secondary infection of a pre-existing bursitis may also occur, though the exact etiology varies by case.

Risk Factors

• Recent injury or surgery near the hip bursa
• Skin infections or open wounds in the hip area
• Immunocompromised states (e.g., diabetes, HIV)
• Chronic inflammatory conditions (e.g., rheumatoid arthritis)
• Repetitive motion or pressure on the hip bursa

Symptoms

• Localized pain, swelling, and warmth over the hip bursa
• Redness or erythema at the site
• Fever or systemic signs of infection
• Limited range of motion in the hip joint
• Pus drainage if the infection progresses

Diagnosis

Diagnosis involves a physical examination to assess bursal characteristics, including tenderness, warmth, and swelling. Imaging studies (e.g., ultrasound or MRI) may be used to evaluate the bursa and surrounding tissues. Aspiration of the bursa for fluid analysis (e.g., culture, Gram stain) can confirm infection and identify causative organisms.

Treatment Options

Treatment typically includes antibiotic therapy targeted at the identified or suspected pathogen. Drainage of the infected bursa may be necessary in severe cases. Rest, ice, and elevation of the hip can help reduce inflammation. Physical therapy may be recommended to restore mobility and strength once the infection is controlled.

Prognosis and Follow-Up

With appropriate treatment, most cases of infective bursitis resolve without long-term complications. Follow-up care ensures the infection is fully cleared and monitors for recurrence. Delayed or inadequate treatment may lead to chronic bursitis or spread of infection.

Complications

Potential complications include chronic bursitis, abscess formation, sepsis, or spread of infection to adjacent tissues or joints. Untreated infection may result in permanent damage to the bursa or hip joint.

Lifestyle & Prevention

• Maintain good skin hygiene to prevent infections
• Protect the hip from trauma or excessive pressure
• Manage underlying conditions (e.g., diabetes) to reduce infection risk
• Avoid repetitive motions that strain the hip bursa

When to Seek Professional Help

Seek medical attention if you experience persistent hip pain, swelling, redness, fever, or pus drainage. Prompt evaluation is important to prevent complications and ensure appropriate treatment.

Tips for Medical Coders

Use M71.159 for other infective bursitis of the unspecified hip. Document the site (unspecified) and confirm the infective nature of the bursitis. Ensure clinical documentation supports the diagnosis and excludes more specific codes when applicable.
