ICD-10 Code L10.8 – Other Pemphigus (2026): Diagnosis, Symptoms & Billing Guide
2026 ICD-10-CM Diagnosis Code L10.8 – Other pemphigus
What it is
L10.8 identifies pemphigus forms that do not fit the more specific pemphigus codes. Use it for autoimmune blistering disease when documentation says “other pemphigus” or gives a pemphigus subtype not named elsewhere.
Clinical signs
Typical findings include fragile blisters, erosions, and skin or mucosal involvement. Clinical features vary; refer to documentation, especially when the record does not clearly match a more specific pemphigus subtype.
When to use this code
Use L10.8 when the clinician documents other pemphigus, unspecified pemphigus subtype, or a pemphigus variant not separately listed in ICD-10-CM. It also fits cases where the diagnosis is confirmed but the exact subtype is not recorded. Check documentation if bullous disease is described without a pemphigus label.
Do not use for
Do not use this code for pemphigus vulgaris, foliaceus, or other specifically named pemphigus codes. Do not assign it for unrelated blistering disorders or when documentation supports a different autoimmune bullous disease.
Coding tip
Query the provider when the chart says “pemphigus” but the subtype is missing, so you can code the most specific documented diagnosis.
