ICD-10 Code L56.8 – Other specified acute skin changes due to ultraviolet radiation (2026): Diagnosis, Symptoms & Billing Guide
2026 ICD-10-CM Diagnosis Code L56.8 – Other specified acute skin changes due to ultraviolet radiation
What it is
L56.8 identifies acute skin changes caused by ultraviolet exposure that do not fit a more specific ICD-10 category. Use it when documentation describes a UV-related skin reaction, but the exact condition is not named elsewhere.
Clinical signs
Findings may include redness, tenderness, swelling, itching, or other acute irritation after sun or UV exposure. Clinical features vary; refer to documentation for the specific reaction described.
When to use this code
Use this code when the record states an acute skin change from ultraviolet radiation and the provider does not document a more specific diagnosis. It may apply after sun exposure, tanning bed exposure, or other UV sources when details are limited. Code the documented condition first if a more specific term is available.
Do not use for
Do not use L56.8 for sunburn, photodermatitis, or other named UV-related disorders when those diagnoses are documented. If the record is unclear, check documentation before assigning this code.
Coding tip
Look for the provider’s exact wording and choose the most specific UV-related code supported by the note.
