M71.132 Other infective bursitis, left wrist

Name of the Condition

• Other infective bursitis, left wrist

Summary

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

Causes

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

Symptoms

• Localized pain, swelling, and warmth over the left wrist bursa
• Redness or erythema at the site
• Fever or systemic signs of infection
• Limited range of motion in the left 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 agent. Clinical correlation with patient history and symptoms is essential for accurate diagnosis.

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 in severe cases. Rest, elevation, and pain management support recovery. Surgical intervention is rare but may be required for persistent or complicated infections.

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 symptoms and potential recurrence. Patients with underlying risk factors may require longer monitoring to prevent complications.

Complications

Untreated or severe infections can lead to abscess formation, sepsis, or chronic bursitis. Spread of infection to adjacent tissues or joints may occur, potentially causing long-term functional impairment of the left wrist.

Lifestyle & Prevention

Avoid repetitive wrist strain and protect the left wrist from injury. Maintain good skin hygiene to prevent infections. Manage chronic conditions (e.g., diabetes) to reduce infection risk. Promptly treat minor wounds or skin infections near the wrist.

When to Seek Professional Help

Seek care if symptoms worsen (e.g., increasing pain, swelling, or fever), if pus drainage occurs, or if the left wrist shows signs of severe infection (e.g., red streaks, systemic illness). Early intervention prevents complications.

Tips for Medical Coders

Code M71.132 is specific to infective bursitis of the left wrist. Documentation must specify the left wrist as the site and confirm infective etiology. Ensure clinical notes support the diagnosis, as this code excludes non-infective bursitis or bursitis at other sites.
