H60.13 Cellulitis of external ear, bilateral

Name of the Condition

• Cellulitis of external ear, bilateral

Summary

Cellulitis of the external ear, bilateral, is an infection of the skin and underlying tissue affecting both outer ears. The condition typically causes localized inflammation and discomfort and is treatable with appropriate medical intervention.

Causes

Cellulitis of the external ear is most commonly caused by bacterial infections, such as Staphylococcus aureus or Streptococcus species. These infections may arise from breaks in the skin, such as trauma, insect bites, or pre-existing skin conditions that allow bacteria to enter and spread.

Risk Factors

• Recent injury or trauma to the ear
• Skin conditions (e.g., eczema, psoriasis)
• Weakened immune system
• Chronic ear infections or drainage
• Exposure to contaminated water or objects

Symptoms

• Redness, swelling, and warmth of the ear
• Pain or tenderness, often worsening with touch
• Skin tightness or hardness in the affected area
• Possible fever or general malaise
• Drainage or pus in severe cases

Diagnosis

Diagnosis is typically made through a physical examination of the ear and surrounding tissue. A healthcare provider may assess for redness, swelling, or warmth. In some cases, a sample of drainage or tissue may be cultured to identify the causative organism.

Treatment Options

• Antibiotic therapy, often oral, tailored to the causative bacteria
• Warm compresses to reduce discomfort and swelling
• Pain management with over-the-counter or prescription medications
• Follow-up care to monitor response to treatment

Prognosis and Follow-Up

With prompt and appropriate treatment, most cases of bilateral external ear cellulitis resolve without complications. Follow-up may be recommended to ensure the infection has cleared and to address any underlying risk factors.

Complications

• Spread of infection to deeper tissues or surrounding structures
• Abscess formation
• Recurrent infections
• Hearing impairment if the infection affects the ear canal or middle ear

Lifestyle & Prevention

• Avoid trauma or injury to the ears
• Keep ears clean and dry
• Treat skin conditions promptly
• Avoid exposure to contaminated water or objects
• Maintain good hygiene practices

When to Seek Professional Help

Seek medical attention if symptoms worsen, do not improve with home care, or if signs of systemic infection (e.g., high fever, severe pain) develop.

Tips for Medical Coders

When coding for H60.13 (Cellulitis of external ear, bilateral), ensure documentation specifies bilateral involvement. Verify that the condition is not associated with other ear conditions (e.g., otitis externa) that may require additional coding. Accurate clinical documentation of bilateral presentation is essential for correct code assignment.
