M71.142 Other infective bursitis, left hand

Name of the Condition

• Other infective bursitis, left hand

Summary

Other infective bursitis, left hand, refers to an infection of a bursa (a small fluid-filled sac that reduces friction between tissues) in the left hand 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 affected hand structures.

Causes

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

Symptoms

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

Diagnosis

Diagnosis involves a physical examination to assess bursal characteristics, including tenderness, warmth, and swelling. Imaging (e.g., ultrasound) may be used to evaluate the bursa. Aspiration of the bursa for fluid analysis (e.g., Gram stain, culture) helps identify the causative organism. Clinical correlation with symptoms and history is essential to confirm infection.

Treatment Options

Treatment typically includes antibiotic therapy targeted at the identified or suspected pathogen. Drainage of the infected bursa may be necessary for abscess formation. Rest, elevation, and pain management support recovery. Severe or refractory cases may require surgical intervention.

Prognosis and Follow-Up

Prognosis depends on early treatment and the absence of complications. Most cases resolve with appropriate therapy, but delayed care can lead to chronic bursitis or spread of infection. Follow-up ensures resolution of symptoms and monitors for recurrence or complications.

Complications

• Spread of infection to surrounding tissues or joints
• Chronic bursitis or bursal thickening
• Functional impairment of the left hand
• Systemic infection (e.g., sepsis) in severe cases

Lifestyle & Prevention

• Avoid trauma or repetitive pressure to the left hand bursa
• Promptly treat skin infections or wounds in the area
• Maintain good hand hygiene
• Manage underlying conditions (e.g., diabetes) to reduce infection risk

When to Seek Professional Help

Seek care if symptoms worsen, persist beyond a few days, or include fever, increasing pain, or pus drainage. Early evaluation is critical to prevent complications.

Tips for Medical Coders

Document the specific site (left hand) and confirm infective etiology. Ensure clinical documentation supports the diagnosis and excludes more specific infective bursitis codes. Code M71.142 is appropriate when the left hand is the documented site and no more specific code applies.
