L08.9
ICD-10-CMLocal infection of the skin and subcutaneous tissue, unspecified
This code represents a localized inflammatory process affecting the skin and underlying subcutaneous layers, where the specific type of infection (e.g., bacterial, fungal, viral) or its precise anatomical location is not documented. It indicates the presence of an infection without further specification of its etiology or exact site.
Use this code when documentation indicates a skin infection, such as cellulitis, abscess, or impetigo, but the provider has not specified the causative organism or a more precise anatomical site. This code is appropriate when the medical record lacks the detail to assign a more specific code from categories such as L00-L08.8.
