ICD-10 Code L57.5 – Actinic granuloma (2026): Diagnosis, Symptoms & Billing Guide
2026 ICD-10-CM Diagnosis Code L57.5 – Actinic granuloma
What it is
L57.5 identifies actinic granuloma, a granulomatous skin disorder linked to sun-damaged areas. Use it for documented actinic granuloma, not for general photodamage or other granulomas.
Clinical signs
Typical findings include annular or ring-shaped plaques on sun-exposed skin, often with central clearing. Clinical features vary; refer to documentation.
When to use this code
Use L57.5 when the clinician specifically diagnoses actinic granuloma in the assessment or pathology report. It is appropriate when the record links the lesion to actinic granuloma rather than another inflammatory or neoplastic skin condition.
If the note only says “rash,” “granuloma,” or “sun damage,” you should not assume this code. Check documentation for the exact diagnosis and site details if needed.
Do not use for
Do not use this code for actinic keratosis, solar lentigo, or other sun-related lesions without a documented actinic granuloma diagnosis. Check documentation when the terminology is unclear.
Coding tip
Code L57.5 only when the provider clearly names actinic granuloma; otherwise, query for clarification.
