M71.13 Other infective bursitis, wrist

Name of the Condition

• Other infective bursitis, wrist

Summary

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

Causes

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

Symptoms

• Localized pain, swelling, and warmth over the wrist bursa
• Redness or erythema at the site
• Fever or systemic signs of infection
• Limited range of motion in the 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. Aspiration of the bursal fluid for culture and sensitivity testing helps identify the causative organism and guide treatment.

Treatment Options

Treatment typically includes antibiotic therapy targeted at the identified organism, often initiated empirically before culture results. Surgical drainage may be necessary for abscess formation or severe infection. Rest, elevation, and pain management support recovery. Physical therapy may be recommended to restore function once the infection resolves.

Prognosis and Follow-Up

With prompt treatment, prognosis is generally favorable. Follow-up care ensures resolution of infection and monitors for recurrence. Chronic or untreated cases may lead to persistent pain or functional limitations. Regular assessments help adjust treatment as needed.

Complications

Potential complications include chronic bursitis, joint stiffness, or spread of infection to surrounding tissues. Rarely, sepsis may occur if the infection is not controlled. Early intervention reduces these risks.

Lifestyle & Prevention

Avoid repetitive wrist motions or pressure on the bursa. Maintain good skin hygiene to prevent infections. Protect the wrist from trauma, and seek prompt care for wounds or skin infections in the area.

When to Seek Professional Help

Seek medical attention if wrist pain, swelling, or redness persists or worsens. Fever, pus drainage, or inability to move the wrist requires immediate evaluation to prevent complications.

Tips for Medical Coders

Use M71.13 for other infective bursitis specifically affecting the wrist. Ensure clinical documentation specifies the wrist as the site of infection to support this code. Differentiate from generalized or unspecified infective bursitis codes when site is clearly identified.
