L02.423 Furuncle of right upper limb

Name of the Condition

• Furuncle of Right Upper Limb (ICD-10 L02.423)

Summary

A furuncle of the right upper limb is a localized skin infection that forms a pus-filled pocket beneath the skin. It typically causes 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 right upper 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 right upper 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.
• Formation of a carbuncle (cluster of furuncles).
• Systemic infection (rare but possible in severe cases).

Lifestyle & Prevention

• Maintain good hygiene, especially in the affected area.
• Avoid sharing personal items (e.g., towels, razors).
• Keep skin clean and dry.
• Promptly treat minor skin injuries to prevent infection.

When to Seek Professional Help

Seek medical attention if the furuncle is large, painful, or does not improve with home care. Also, consult a healthcare provider if there are signs of spreading infection (e.g., fever, red streaks, increased swelling).

Tips for Medical Coders

Document the specific location (right upper limb) and clinical details (e.g., presence of pus, drainage, or systemic symptoms) to support accurate coding. Ensure the code aligns with the clinical documentation of the furuncle’s location and any associated complications.
