M71.072 Abscess of bursa, left ankle and foot

Name of the Condition

• Abscess of bursa, left ankle and foot

Summary

An abscess of the bursa, left ankle and foot is a localized collection of pus within a bursa in the left ankle or foot region. This condition causes pain, swelling, and functional impairment at the affected site. Bursae are small fluid-filled sacs that reduce friction between tissues, and when infected, they can become inflamed and filled with purulent material.

Causes

Abscesses of the bursa typically 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 chronic inflammation or foreign body reaction, may also lead to bursal abscess formation.

Risk Factors

• Recent injury or surgery near a bursa in the left ankle or foot
• Skin infections or open wounds in the vicinity
• Immunocompromised states (e.g., diabetes, HIV)
• Chronic inflammatory conditions (e.g., rheumatoid arthritis)
• Repetitive motion or pressure on the bursa

Symptoms

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

Diagnosis

Diagnosis involves a physical examination to assess bursal characteristics, including tenderness, fluctuance, and warmth. 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 may be necessary for larger or persistent collections. Rest, elevation, and pain management are also important components of care. In some cases, surgical intervention may be required to remove the abscess or address underlying causes.

Prognosis and Follow-Up

With appropriate treatment, most bursal abscesses resolve without long-term complications. Follow-up care ensures the infection is fully resolved and helps monitor for recurrence. Patients should be advised to seek care if symptoms worsen or persist.

Complications

Untreated abscesses can lead to the spread of infection, tissue damage, or chronic bursitis. Rarely, systemic infection (sepsis) may occur if the abscess ruptures or spreads.

Lifestyle & Prevention

• Avoid repetitive pressure or trauma to the left ankle and foot
• Maintain good skin hygiene to prevent infections
• Manage chronic conditions (e.g., diabetes) to reduce infection risk
• Use protective gear during activities that stress the ankle or foot

When to Seek Professional Help

Seek medical attention if you experience persistent pain, swelling, redness, or fever in the left ankle or foot. Prompt care is important if the abscess ruptures or if symptoms worsen.

Tips for Medical Coders

This code specifies an abscess of the bursa in the left ankle and foot. Documentation should clearly indicate the location (left ankle/foot) and the presence of a bursal abscess. Ensure the medical record supports the diagnosis and location to justify code assignment.
