ICD-10 Code L57.3 – Poikiloderma of Civatte (2026): Diagnosis, Symptoms & Billing Guide
2026 ICD-10-CM Diagnosis Code L57.3 – Poikiloderma of Civatte
What it is
Poikiloderma of Civatte is a chronic skin change, usually on the sides of the neck and upper chest. It combines redness, pigment alteration, and thinning of the skin.
Clinical signs
Typical findings include mottled discoloration, telangiectasia, and a sun-exposed distribution. The condition often spares shaded areas under the chin; clinical features vary, so refer to documentation.
When to use this code
Use L57.3 when the record specifically documents poikiloderma of Civatte or confirms this diagnosis on examination. It fits outpatient or specialist notes describing chronic photodamage with the classic neck pattern. If the note only says “rash” or “sun damage,” check documentation before coding.
Do not use for
Do not use this code for nonspecific dermatitis, generalized hyperpigmentation, or other photodermatoses without documented poikiloderma of Civatte. Check documentation if the diagnosis is uncertain.
Coding tip
Code only when the clinician names the condition or clearly documents the characteristic poikiloderma pattern.
