L02.426 Furuncle of left lower limb

Name of the Condition

• Furuncle of Left Lower Limb (ICD-10 L02.426)

Summary

A furuncle of the left lower limb is a localized skin infection that results in a pus-filled pocket, typically caused by bacterial infection. It often presents with pain, swelling, and redness in the affected area and may require medical intervention to resolve.

Causes

Bacterial infection, most commonly Staphylococcus aureus. Blocked hair follicles or sweat glands. Skin breaks or injuries that allow bacteria to enter.

Risk Factors

• Poor hygiene practices.
• Compromised immune system.
• Diabetes or chronic health conditions.
• Use of antibiotics or steroids that disrupt skin flora.
• History of skin infections.

Symptoms

• Pain and tenderness in the affected left lower limb.
• Swelling and redness of the skin.
• Warmth around the infected area.
• Appearance of a lump or boil that may drain pus.

Diagnosis

Physical examination of the left lower limb. Bacterial cultures from pus to identify the organism. Ultrasound may be used to assess the abscess extent.

Treatment Options

• Incision and drainage: Primary treatment to remove pus and relieve pain.
• Antibiotics: Prescribed to treat or prevent further infection.
• Warm compresses: Help reduce swelling and promote drainage.

Prognosis and Follow-Up

Generally favorable if treated promptly. Follow-up may be needed to ensure complete healing and monitor for recurrence.

Complications

• Spread of infection to surrounding tissue (cellulitis).
• Formation of abscesses in nearby areas.
• Systemic infection (sepsis) in severe cases.
• Scarring or skin discoloration after healing.

Lifestyle & Prevention

• Maintain good hygiene, especially in the lower limb area.
• Keep skin clean and dry to prevent bacterial entry.
• Avoid sharing personal items (e.g., towels) to reduce infection risk.
• Promptly treat minor skin injuries to prevent infection.

When to Seek Professional Help

Seek medical attention if the furuncle is large, painful, or worsening. Consult a healthcare provider if there are signs of spreading redness, fever, or systemic symptoms (e.g., chills, fatigue).

Tips for Medical Coders

Document the specific location (left lower limb) and any associated details (e.g., size, drainage, treatment) to support accurate coding. Ensure clinical documentation aligns with the ICD-10-CM code L02.426 for proper classification.
