M71.139 Other infective bursitis, unspecified wrist

Name of the Condition

• Other infective bursitis, unspecified wrist

Summary

Other infective bursitis, unspecified 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, unspecified 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 or fluid aspiration may be used to confirm infection and identify causative organisms.

Treatment Options

Treatment typically includes antibiotic therapy targeted at the identified pathogen. In severe cases, surgical drainage of the infected bursa may be necessary. Rest, elevation, and pain management are also standard components of care.

Prognosis and Follow-Up

With prompt treatment, most cases resolve without long-term complications. Follow-up care ensures infection resolution and monitors for recurrence. Chronic or untreated cases may lead to persistent pain or functional limitations.

Complications

Potential complications include abscess formation, septic arthritis, or spread of infection to surrounding tissues. Delayed treatment increases the risk of these outcomes.

Lifestyle & Prevention

Maintain good skin hygiene and avoid trauma to the wrist area. Manage underlying conditions like diabetes to reduce infection risk. Use protective gear during activities that strain the wrist.

When to Seek Professional Help

Seek care if symptoms worsen, fever develops, or pus drainage occurs. Prompt evaluation is critical to prevent complications.

Tips for Medical Coders

Document the site (unspecified wrist) and confirm infective bursitis as the primary diagnosis. Ensure clinical notes support the absence of more specific wrist or side (right/left) details. Code M71.139 is appropriate when the wrist site is not further specified.
