L02.422 Furuncle of left axilla

Name of the Condition

• Furuncle of Left Axilla (ICD-10 L02.422)

Summary

A furuncle of the left axilla is a localized skin infection that forms 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 left axilla.
• 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 axilla. 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.
• Formation of a carbuncle (cluster of furuncles).
• Systemic infection (rare).

Lifestyle & Prevention

• Maintain good hygiene, especially in the axillary area.
• Avoid sharing personal items (e.g., towels) to prevent bacterial spread.
• Keep skin clean and dry.
• Promptly treat minor skin injuries or breaks.

When to Seek Professional Help

Seek care if the furuncle is large, painful, or does not improve with home care. Immediate medical attention is needed if signs of spreading infection (e.g., fever, red streaks) occur.

Tips for Medical Coders

Document the specific location (left axilla) and clinical findings (e.g., presence of pus, abscess) to support accurate coding. Ensure the code aligns with the documented anatomical site and condition type.
