ICD-10 Code L11.8 – Other specified acantholytic disorders (2026): Diagnosis, Symptoms & Billing Guide
2026 ICD-10-CM Diagnosis Code L11.8 – Other specified acantholytic disorders
What it is
L11.8 is used for acantholytic skin disorders that do not fit a more specific ICD-10 category. It indicates loss of cohesion between epidermal cells, but the exact named condition is not otherwise classified.
Clinical signs
Clinical features vary; refer to documentation. Findings may include fragile skin, blistering, erosions, or crusted lesions consistent with an acantholytic process, but the specific diagnosis should be recorded when known.
When to use this code
Use this code when the provider documents an acantholytic disorder and no more specific ICD-10 code applies. It is appropriate when the chart identifies an “other specified” form or an atypical presentation that is not named elsewhere. Check documentation if the diagnosis is uncertain.
Do not use for
Do not use L11.8 when the record supports a more specific acantholytic disorder code. Do not assign it for nonspecific rash, blistering, or dermatitis without documentation of an acantholytic condition.
Coding tip
Code the most specific documented skin diagnosis first; use L11.8 only when the provider clearly states an unspecified or other specified acantholytic disorder.
