M71.1 Other infective bursitis

Name of the Condition

• Other infective bursitis

Summary

Other infective bursitis refers to an infection of a bursa (a small fluid-filled sac that reduces friction between tissues) that is not classified under more specific infective bursitis codes. This condition involves bacterial or other microbial invasion of the bursa, leading to inflammation, pain, and potential functional impairment at the affected site.

Causes

Other infective bursitis 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 a bursa
• Skin infections or open wounds in the vicinity
• Immunocompromised states (e.g., diabetes, HIV)
• Chronic inflammatory conditions (e.g., rheumatoid arthritis)
• Repetitive motion or pressure on the bursa

Symptoms

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

Diagnosis

Diagnosis involves a physical examination to assess bursal characteristics, including tenderness, fluctuance, and warmth. Imaging (e.g., ultrasound) may confirm fluid collection. Aspiration of bursal fluid for culture and sensitivity testing is often performed to identify the causative organism and guide treatment.

Treatment Options

Treatment typically includes antibiotic therapy targeted at the identified pathogen, often initiated empirically before culture results. Drainage of the infected bursa may be necessary for severe cases. Rest, elevation, and pain management are also standard supportive measures.

Prognosis and Follow-Up

With appropriate antibiotic treatment and drainage if needed, most cases resolve without long-term complications. Follow-up is important to monitor for resolution of symptoms and to adjust therapy based on culture results or clinical response.

Complications

Untreated or inadequately treated infective bursitis can lead to abscess formation, spread of infection to surrounding tissues, or chronic bursal damage. Systemic infection (sepsis) is a rare but serious risk in severe cases.

Lifestyle & Prevention

• Avoid repetitive pressure or trauma to bursae
• Maintain good skin hygiene to prevent infection
• Manage underlying conditions (e.g., diabetes) that increase infection risk
• Use protective gear during activities that stress joints

When to Seek Professional Help

Seek medical attention if you experience persistent pain, swelling, redness, or fever near a joint, especially if symptoms worsen or do not improve with rest. Prompt evaluation is important to prevent complications.

Tips for Medical Coders

Document the specific bursa involved and confirm infective etiology (e.g., via culture or clinical signs of infection) to support code assignment. Ensure documentation aligns with the "other" designation, as this code is used when the infective bursitis does not fall under more specific categories.
