M71.032 Abscess of bursa, left wrist

Name of the Condition

• Abscess of bursa, left wrist

Summary

An abscess of the bursa, left wrist is a localized collection of pus within the bursa of the left wrist, a small fluid-filled sac that reduces friction between tissues. This condition typically causes pain, swelling, and warmth at the affected site. The left wrist-specific designation indicates the abscess is localized to the bursa in the left wrist region.

Causes

Abscesses of the left wrist bursa usually result from bacterial infection, often introduced through direct trauma, skin breakdown, or spread from adjacent tissues. Staphylococcus aureus is a common causative organism. Non-infectious causes, such as foreign body reaction or sterile inflammation, are less frequent.

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, tenderness, or throbbing in the left wrist
• Swelling, redness, or warmth over the bursa
• Limited range of motion in the left wrist joint
• Possible fever or systemic signs if infection spreads
• Pus drainage if the abscess ruptures

Diagnosis

Diagnosis involves a physical examination to assess bursal swelling, warmth, and tenderness. Imaging (e.g., ultrasound) may confirm fluid collection. Aspiration of the bursa may be performed to identify the causative organism and guide treatment.

Treatment Options

Treatment typically includes antibiotic therapy for bacterial infections, often targeting Staphylococcus aureus. Drainage of the abscess may be necessary if it does not resolve with antibiotics alone. Rest, elevation, and pain management are also recommended. In some cases, surgical intervention may be required to remove the abscess.

Prognosis and Follow-Up

With appropriate treatment, most abscesses of the left wrist bursa resolve without long-term complications. Follow-up care may include monitoring for recurrence or signs of spreading infection. Physical therapy may be recommended to restore wrist function if mobility is affected.

Complications

Untreated or inadequately treated abscesses can lead to the spread of infection to surrounding tissues or bloodstream. Chronic bursitis or persistent pain may occur if the abscess recurs. Rarely, surgical intervention may be needed to prevent further complications.

Lifestyle & Prevention

Avoid repetitive wrist motions or excessive pressure on the left wrist. Maintain good skin hygiene and promptly treat any wrist injuries or infections. If you have a chronic inflammatory condition, work with your healthcare provider to manage it effectively.

When to Seek Professional Help

Seek medical attention if you experience persistent wrist pain, swelling, or warmth, especially if accompanied by fever or pus drainage. Prompt evaluation is important to prevent the spread of infection and ensure appropriate treatment.

Tips for Medical Coders

This code (M71.032) is specific to an abscess of the bursa in the left wrist. Documentation should clearly indicate the location (left wrist) and confirm the presence of a bursal abscess. Ensure the medical record supports the diagnosis with clinical findings, such as physical examination or imaging results, to justify code assignment.
