L02.412 Cutaneous abscess of left axilla

Name of the Condition

• Cutaneous Abscess of Left Axilla (ICD-10 L02.412)
• Also known as an armpit abscess.

Summary

A cutaneous abscess of the left axilla is a localized infection in the armpit area that leads to the formation of a pus-filled pocket beneath the skin. It is typically painful and can cause swelling and redness of the affected area.

Causes

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

Risk Factors

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

Symptoms

• Pain and tenderness in the armpit.
• Swelling and redness of the skin.
• Warmth around the affected area.
• Appearance of a lump or boil that may weep pus.

Diagnosis

Physical examination of the affected area. Bacterial cultures from pus to identify the causative organism. Ultrasound may be used to view the extent of the abscess.

Treatment Options

• Incision and drainage: Primary treatment to remove pus and alleviate pain.
• Antibiotics: Used to treat or prevent further bacterial 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 to monitor for recurrence.

Complications

• Spread of infection to surrounding tissues.
• Formation of a chronic abscess.
• Systemic infection if left untreated.

Lifestyle & Prevention

• Maintain good hygiene, especially in the armpit area.
• Avoid sharing personal items that may spread bacteria.
• Keep skin clean and dry to prevent breaks or irritation.

When to Seek Professional Help

• If the abscess is large, painful, or worsening.
• If you develop fever, chills, or other signs of systemic infection.
• If the abscess does not improve with home care or drainage.

Tips for Medical Coders

• Ensure documentation specifies the location as the left axilla.
• Note the presence of drainage, culture results, or treatment details to support code assignment.
• Verify that the diagnosis aligns with clinical findings and is clearly documented in the medical record.
