Cutaneous abscess of other sites

This code signifies a localized collection of pus within the skin and subcutaneous tissue, occurring in anatomical locations not specified by more granular codes. It represents an infection that has led to tissue necrosis and purulent exudate formation, typically presenting as a tender, erythematous, fluctuant nodule.

Apply this code when documentation specifies a cutaneous abscess in a site such as the back, chest wall, abdomen, or extremities, and no more specific ICD-10-CM code exists for that particular body region. Supporting documentation should clearly identify the presence of an abscess and its non-specific anatomical location.

• Ensure the documentation explicitly states "abscess" and specifies a non-classified anatomical site.
• Differentiate from cellulitis (L03.-) or furuncle/carbuncle (L02.0-L02.6) which have distinct clinical presentations and coding.
• Always look for a more specific code first; this code is for "other sites" when no better option is available.
