Name of the Condition

• Non-bullous Impetigo
• Also known as impetigo contagiosa or crusted impetigo.

Summary

• Non-bullous impetigo is a highly contagious skin infection primarily affecting children. It is characterized by red sores that rapidly rupture, ooze for a few days, and then form a yellowish-brown crust.

Causes

• Caused by bacterial infection, commonly attributed to Staphylococcus aureus or Streptococcus pyogenes.

Risk Factors

• Young age, particularly children aged 2-5.
• Warm, humid environments.
• Close contact settings like daycare centers or schools.
• Pre-existing skin conditions, such as eczema.

Symptoms

• Red sores, usually around the nose and mouth, that burst and develop honey-colored crusts.
• Itching and minor discomfort.
• In severe cases, swollen lymph nodes may occur.

Diagnosis

• A physical examination by a healthcare professional.
• In certain cases, a bacterial culture or skin swab may be taken to identify the causative organism.

Treatment Options

• Topical Antibiotics: Mupirocin or fusidic acid cream for smaller, localized infections.
• Oral Antibiotics: Prescribed in more extensive cases to eliminate bacterial infection.
• Proper hygiene practices are encouraged to prevent the spread.

Prognosis and Follow-Up

• With appropriate treatment, non-bullous impetigo usually resolves within 7-10 days.
• Follow-up is generally not necessary unless symptoms persist or complications arise.

Complications

• Possible development of cellulitis or post-streptococcal glomerulonephritis if left untreated.
• Rare cases of scar formation.

Lifestyle & Prevention

• Maintaining good hygiene.
• Regular handwashing and keeping fingernails short to prevent bacteria spread.
• Avoid sharing personal items such as towels or clothing.

When to Seek Professional Help

• If sores do not improve within a few days of treatment or if they spread rapidly.
• If the patient develops a fever or experiences significant pain or swelling.

Tips for Medical Coders

• Ensure accurate history of the lesions to support the diagnosis of non-bullous impetigo.
• Double-check for the distinction between non-bullous and bullous forms of impetigo for precise coding.
• Avoid assuming causative organism without laboratory confirmation.
