M71.171 Other infective bursitis, right ankle and foot

Name of the Condition

• Other infective bursitis, right ankle and foot

Summary

Other infective bursitis, right ankle and foot refers to an infection of a bursa (a small fluid-filled sac that reduces friction between tissues) in the right ankle or foot region. This condition involves microbial invasion of the bursa, leading to inflammation, pain, and potential functional impairment of the affected area. The infection may be bacterial or non-bacterial, and the site specification indicates the condition is localized to the right ankle and foot.

Causes

Other infective bursitis, right ankle and foot 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. The right ankle and foot designation specifies the anatomical location of the infected bursa.

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 right ankle or foot 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 infection progresses

Diagnosis

Diagnosis involves a physical examination to assess bursal characteristics, including tenderness, warmth, and swelling in the right ankle or foot. Imaging (e.g., ultrasound) may confirm bursal involvement, and fluid aspiration for culture can identify the causative organism. Clinical documentation must specify the right ankle or foot as the affected site.

Treatment Options

Treatment typically includes antibiotic therapy targeted at the identified pathogen, often empirically covering Staphylococcus aureus. Rest, elevation, and compression of the right ankle or foot may reduce inflammation. Severe cases may require surgical drainage of the infected bursa. Pain management and physical therapy are used to restore function as inflammation subsides.

Prognosis and Follow-Up

Prognosis is generally favorable with prompt treatment, though delays can lead to chronic pain or functional impairment. Follow-up involves monitoring for resolution of symptoms and signs of infection. Repeat imaging or fluid analysis may be performed if symptoms persist or worsen.

Complications

• Chronic bursitis or persistent pain
• Spread of infection to adjacent tissues or bones
• Limited mobility in the right ankle or foot
• Recurrence of infection if underlying causes are not addressed

Lifestyle & Prevention

• Avoid repetitive pressure or trauma to the right ankle/foot
• Maintain good foot hygiene and promptly treat skin injuries
• Manage chronic conditions (e.g., diabetes) to reduce infection risk
• Use protective footwear during activities that stress the ankle/foot

When to Seek Professional Help

Seek care if symptoms worsen (e.g., increased pain, swelling, fever) or if pus drainage occurs. Prompt evaluation is necessary if mobility in the right ankle or foot is significantly limited or if systemic signs of infection develop.

Tips for Medical Coders

Document the specific site (right ankle and foot) and confirm infective bursitis is the primary diagnosis. Ensure clinical notes specify the anatomical location to support code assignment. Differentiate from non-infective bursitis or other bursal conditions to avoid miscoding.
