M71.071 Abscess of bursa, right ankle and foot

Name of the Condition

• Abscess of bursa, right ankle and foot

Summary

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

Causes

Abscesses of the bursa in the right ankle and foot 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, may also lead to bursal abscess formation.

Risk Factors

• Recent injury or surgery near the right ankle or foot bursa
• Skin infections or open wounds in the right ankle/foot area
• Immunocompromised states (e.g., diabetes, HIV)
• Chronic inflammatory conditions (e.g., rheumatoid arthritis)
• Repetitive motion or pressure on the right ankle/foot 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 the right ankle or foot
• 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 infection, often with drainage of the abscess if necessary. Rest, elevation, and pain management may also be recommended. In severe cases, surgical intervention may be required to remove the abscess and promote healing.

Prognosis and Follow-Up

With appropriate treatment, most bursal abscesses 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 function if mobility is affected.

Complications

Untreated 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 mobility. Rarely, tissue damage or joint involvement may occur.

Lifestyle & Prevention

• Maintain good foot hygiene to reduce infection risk
• Wear properly fitting footwear to avoid pressure on the bursa
• Address minor injuries or skin breaks promptly
• Manage underlying conditions like diabetes to support immune function
• Avoid repetitive motions that strain the right ankle or foot

When to Seek Professional Help

Seek medical attention if you experience increasing pain, swelling, or redness in the right ankle or foot, fever, or pus drainage. Prompt care is important to prevent complications and ensure proper treatment.

Tips for Medical Coders

Document the specific location (right ankle and foot) and confirm the presence of an abscess. Ensure clinical notes support the diagnosis, including signs of infection or fluid collection. Verify that the code aligns with the documented site and condition to ensure accurate coding.
