ICD-10 Code L12.8 – Other pemphigoid (2026): Diagnosis, Symptoms & Billing Guide
2026 ICD-10-CM Diagnosis Code L12.8 – Other pemphigoid
What it is
L12.8 identifies pemphigoid conditions that do not fit a more specific pemphigoid code. It is used for autoimmune blistering disease involving the skin or mucous membranes when documentation supports pemphigoid but not a named subtype.
Clinical signs
Typical findings include tense blisters, itching, and inflammation, often on the skin. Clinical features vary; refer to documentation, especially when the record describes a pemphigoid diagnosis without specifying the exact form.
When to use this code
Use L12.8 when the provider documents “other pemphigoid,” “pemphigoid NOS,” or a pemphigoid disorder not captured elsewhere in the L12 category. You should code it only when the chart clearly supports pemphigoid and no more specific diagnosis is recorded.
Do not use for
Do not use this code for bullous disorders that are not pemphigoid, or when a more specific pemphigoid code is documented. Check documentation if the condition is named differently or if the record is incomplete.
Coding tip
Verify the exact pemphigoid subtype in the note before assigning L12.8.
