ICD-10 Code L01.02 – Bockhart’s Impetigo (2026): Diagnosis, Symptoms & Billing Guide
2026 ICD-10-CM Diagnosis Code L01.02 – Bockhart’s impetigo
What it is
Bockhart’s impetigo is a superficial bacterial skin infection centered on hair follicles. It is a localized form of impetigo, usually described as follicular pustules or crusted lesions.
Clinical signs
Clinical features vary; refer to documentation. Typical findings include small pustules, crusting, and inflammation around hair follicles, often on exposed skin.
When to use this code
Use L01.02 when the provider documents Bockhart’s impetigo, follicular impetigo, or a clearly identified superficial follicular bacterial infection. Code it from the diagnosis statement, not from nonspecific rash or dermatitis language. If the record only says impetigo without this subtype, check documentation.
Do not use for
Do not use this code for nonfollicular impetigo, cellulitis, eczema, or an unspecified skin eruption. If the lesion type or diagnosis is unclear, check documentation.
Coding tip
Capture the exact subtype wording; specificity matters when the record distinguishes follicular impetigo from other impetigo forms.
