ICD-10 Code L30.5 – Pityriasis alba (2026): Diagnosis, Symptoms & Billing Guide
2026 ICD-10-CM Diagnosis Code L30.5 – Pityriasis alba
What it is
L30.5 identifies pityriasis alba, a mild skin condition marked by light-colored patches, usually on the face. It is generally benign and often seen in children or adolescents.
Clinical signs
Typical findings include round or oval hypopigmented patches with fine scale and mild dryness. Clinical features vary; refer to documentation if the appearance is atypical.
When to use this code
Use this code when the provider documents pityriasis alba or a diagnosis clearly matching that condition. It is appropriate when the record describes benign hypopigmented facial patches and does not indicate another specific disorder. Check documentation if the note is vague.
Do not use for
Do not use L30.5 for vitiligo, tinea versicolor, or other clearly different causes of pigment change. If the diagnosis is uncertain or another skin disease is recorded, code the documented condition instead.
Coding tip
Code only when pityriasis alba is explicitly documented or strongly supported by the note.
