ICD-10 Code L12.30 – Acquired epidermolysis bullosa, unspecified (2026): Diagnosis, Symptoms & Billing Guide
2026 ICD-10-CM Diagnosis Code L12.30 – Acquired epidermolysis bullosa, unspecified
What it is
This code identifies acquired epidermolysis bullosa when the specific subtype is not documented. It refers to a rare blistering disorder that develops after birth and is not inherited.
Clinical signs
Typical findings include skin fragility, tense blisters, and erosions after minor trauma. Clinical features vary; refer to documentation, especially if mucosal involvement or scarring is noted.
When to use this code
Use L12.30 when the provider documents acquired epidermolysis bullosa but does not specify a more exact type. It may also apply when the record confirms the diagnosis and the chart lacks subtype detail. Code the documented condition, not a presumed inherited blistering disorder.
Do not use for
Do not use this code for inherited epidermolysis bullosa or for nonspecific blistering without a confirmed diagnosis. Check documentation if the record only describes skin fragility, bullae, or a suspected autoimmune blistering disease.
Coding tip
If the note says “epidermolysis bullosa” without acquired status, verify whether the condition is inherited or acquired before assigning L12.30.
