ICD-10 Code L94.0 – Localized scleroderma [morphea] (2026): Diagnosis, Symptoms & Billing Guide
2026 ICD-10-CM Diagnosis Code L94.0 – Localized scleroderma [morphea]
What it is
L94.0 identifies localized scleroderma, also called morphea. It is a skin-limited fibrosing disorder that causes areas of hardening and thickening without the widespread organ involvement seen in systemic sclerosis.
Clinical signs
You may see one or more firm, indurated plaques with a smooth, shiny, or bound-down appearance. Lesions can be round, oval, linear, or generalized; clinical features vary, so refer to documentation.
When to use this code
Use L94.0 when the provider documents localized scleroderma or morphea, including plaque, linear, or other localized forms. Apply it when the condition is confined to the skin or underlying tissue and not described as systemic sclerosis. If the note is unclear, check documentation for the exact diagnosis.
Do not use for
Do not use this code for systemic sclerosis, scleroderma with internal organ involvement, or nonspecific skin thickening without a confirmed diagnosis. Check documentation if the record only says “scleroderma” or “fibrosis.”
Coding tip
Confirm the provider specifically documents morphea or localized scleroderma before assigning L94.0.
