M71.131 Other infective bursitis, right wrist

Name of the Condition

• Other infective bursitis, right wrist

Summary

Other infective bursitis, right wrist refers to an infection of the bursa in the right wrist 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 right wrist joint.

Causes

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

Symptoms

• Localized pain, swelling, and warmth over the right wrist bursa
• Redness or erythema at the site
• Fever or systemic signs of infection
• Limited range of motion in the right wrist 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) may be used to evaluate the bursa, and fluid aspiration for culture can confirm the infectious organism. Clinical correlation with symptoms and history is essential for accurate diagnosis.

Treatment Options

Treatment typically includes antibiotic therapy targeted at the identified organism, often initiated empirically before culture results. Rest, elevation, and compression of the right wrist may reduce symptoms. Severe cases may require surgical drainage or debridement to remove infected fluid or tissue.

Prognosis and Follow-Up

With prompt treatment, prognosis is generally favorable, though residual stiffness or pain may persist. Follow-up appointments monitor for resolution of infection and functional recovery. Chronic or untreated cases may lead to persistent bursal damage or recurrence.

Complications

Potential complications include abscess formation, spread of infection to surrounding tissues or bloodstream (sepsis), chronic bursitis, or permanent joint dysfunction if the infection causes structural damage.

Lifestyle & Prevention

• Avoid repetitive wrist motions or excessive pressure on the right wrist.
• Maintain good skin hygiene and promptly treat wrist injuries or infections.
• Use protective gear during activities that risk wrist trauma.
• Manage underlying conditions (e.g., diabetes) to reduce infection risk.

When to Seek Professional Help

Seek care if symptoms worsen (e.g., increasing pain, swelling, or fever), if pus drainage occurs, or if wrist function is significantly impaired. Immediate evaluation is necessary for signs of systemic infection (e.g., chills, confusion) or if home care measures fail to improve symptoms.

Tips for Medical Coders

Code M71.131 is specific to infective bursitis of the right wrist. Documentation should specify the site (right wrist) and confirm infective etiology. Ensure clinical notes support the diagnosis, as this code excludes non-infective bursitis or bursitis at other sites. Verify that no more specific infective bursitis code applies before using this code.
