L02.2 Cutaneous abscess, furuncle and carbuncle of trunk

Name of the Condition

• Cutaneous abscess, furuncle and carbuncle of trunk
• Medical Term: Abscess, furuncle, or carbuncle of the trunk

Summary

A cutaneous abscess, furuncle, or carbuncle of the trunk is a localized collection of pus in the skin of the trunk (chest, abdomen, back, or flank), typically resulting from a bacterial infection. It may present as a single furuncle (boil), a cluster of furuncles (carbuncle), or a larger abscess, often causing pain, redness, and swelling.

Causes

Bacterial infection, most commonly by Staphylococcus aureus. Entry of bacteria through breaks in the skin (e.g., cuts, hair follicle blockage). Spread of infection from nearby areas or systemic sources.

Risk Factors

• Poor hygiene or skin irritation.
• Weakened immune system (e.g., diabetes, immunosuppression).
• Skin conditions like acne or eczema.
• Obesity or friction from clothing.

Symptoms

• Painful, raised lump on the trunk.
• Redness, warmth, and swelling at the site.
• Possible pus drainage if the lesion ruptures.
• Fever or malaise in severe cases.

Diagnosis

Physical examination to assess the lesion’s appearance and location. Imaging (e.g., ultrasound) if deep tissue involvement is suspected. Pus culture to identify the causative bacteria (if drained).

Treatment Options

• Incision and drainage to remove pus.
• Antibiotics to treat the underlying infection.
• Warm compresses to promote drainage.
• Pain management with analgesics.

Prognosis and Follow-Up

With prompt treatment, most cases resolve without complications. Follow-up may be needed to monitor healing or adjust antibiotics. Recurrence is possible if risk factors persist.

Complications

• Spread of infection to deeper tissues (cellulitis).
• Scarring or tissue damage.
• Sepsis in severe or untreated cases.

Lifestyle & Prevention

• Maintain good hygiene, especially after skin injuries.
• Avoid sharing personal items (e.g., towels) to prevent bacterial spread.
• Manage underlying conditions (e.g., diabetes) to support immune function.
• Wear loose, breathable clothing to reduce skin friction.

When to Seek Professional Help

• If the abscess is large, worsening, or accompanied by fever.
• If drainage is excessive or fails to improve with home care.
• If symptoms persist beyond a few days or recur.

Tips for Medical Coders

• Code L02.2 is used for cutaneous abscess, furuncle, or carbuncle of the trunk.
• Document the specific location (e.g., chest, abdomen) and whether it is a furuncle, carbuncle, or abscess.
• Include details on treatment (e.g., drainage, antibiotics) and any complications for accurate coding.
