ICD-10 Code L12.35 – Other acquired epidermolysis bullosa (2026): Diagnosis, Symptoms & Billing Guide
2026 ICD-10-CM Diagnosis Code L12.35 – Other acquired epidermolysis bullosa
What it is
This code identifies acquired epidermolysis bullosa, a rare blistering disorder that develops after birth and is not inherited. Use it when documentation specifies an acquired form that does not fit a more specific subtype.
Clinical signs
Typical findings include skin fragility, blistering, and erosions after minor trauma. Clinical features vary; refer to documentation for the exact pattern, severity, and any mucosal involvement.
When to use this code
Use L12.35 when the record clearly states other acquired epidermolysis bullosa or acquired EB without a more specific code. It may also apply when the clinician documents a nonhereditary blistering disorder consistent with acquired EB. Check documentation if the type is uncertain.
Do not use for
Do not use this code for inherited epidermolysis bullosa or for unspecified blistering disorders. If the note describes a different bullous disease, choose the documented condition instead.
Coding tip
Code only when the provider documents the acquired nature of the disease and the diagnosis is explicit.
