L11.9
ICD-10-CMThis code represents an unspecific diagnosis of an acantholytic disorder, which is a dermatological condition characterized by the loss of cohesion between keratinocytes in the epidermis. This cellular detachment leads to the formation of intraepidermal blisters or erosions. It encompasses a range of conditions where the primary pathological feature is acantholysis, without further specification of the underlying cause or specific type.
Use this code when documentation indicates an acantholytic disorder but lacks sufficient detail to specify a more precise diagnosis, such as pemphigus vulgaris, Darier's disease, or Hailey-Hailey disease. This code is appropriate when the provider has diagnosed acantholysis but has not yet identified the specific subtype or etiology. Supporting documentation would typically include a pathology report confirming acantholysis without further definitive classification.
