ICD-10 Code L70.2 – Acne varioliformis (2026): Diagnosis, Symptoms & Billing Guide
2026 ICD-10-CM Diagnosis Code L70.2 – Acne varioliformis
What it is
L70.2 identifies acne varioliformis, a rare inflammatory skin disorder that causes acne-like lesions. You use it when the record specifically names this diagnosis.
Clinical signs
Typical findings include papules or pustules that can crust and heal with pitted or varioliform scarring. Clinical features vary; refer to documentation.
When to use this code
Use this code when the clinician documents acne varioliformis, including cases described as varioliform acne or acne with characteristic scar formation. Code it from the final diagnosis in the note, not from a suspected skin eruption alone.
Do not use for
Do not use L70.2 for common acne vulgaris or other unspecified acne disorders. Check documentation if the note only describes nonspecific facial papules, folliculitis, or scarring without naming acne varioliformis.
Coding tip
Confirm the exact term in the assessment, because the diagnosis must be explicitly documented to support L70.2.
