M71.031 Abscess of bursa, right wrist

Name of the Condition

• Abscess of bursa, right wrist

Summary

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

Causes

Abscesses of the right 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 right 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 right wrist bursa

Symptoms

• Localized pain, tenderness, or throbbing in the right wrist
• Swelling, redness, or warmth over the bursa
• Limited range of motion in the 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 to address the underlying infection. Drainage of the abscess, either through needle aspiration or surgical incision, may be necessary to remove pus and relieve pressure. Rest, elevation, and pain management are also important components of care.

Prognosis and Follow-Up

With appropriate treatment, most bursal abscesses resolve without long-term complications. Follow-up care may include monitoring for recurrence, assessing wound healing, and ensuring the infection has been fully eradicated. Physical therapy may be recommended to restore function if mobility is impaired.

Complications

Untreated or inadequately treated abscesses can lead to the spread of infection to surrounding tissues or bloodstream (sepsis). Chronic inflammation or scarring may result in persistent pain or limited joint mobility. Rarely, surgical intervention may be required to address complications.

Lifestyle & Prevention

Avoiding repetitive wrist movements or excessive pressure can reduce strain on the bursa. Maintaining good skin hygiene and promptly treating wrist injuries or infections may help prevent abscess formation. Using protective gear during activities that risk wrist trauma is also advisable.

When to Seek Professional Help

Seek medical attention if you experience persistent wrist pain, swelling, or redness, especially with fever or pus drainage. Early evaluation is important to prevent infection spread and ensure appropriate treatment.

Tips for Medical Coders

Document the specific location (right wrist) and confirm the presence of a bursal abscess. Ensure clinical documentation supports the diagnosis and any associated procedures, such as drainage or antibiotic therapy. Verify that the code aligns with the anatomical site and condition described.
