Cellulitis, unspecified

This code signifies an acute, spreading bacterial infection of the skin and subcutaneous tissues, characterized by erythema, warmth, swelling, and pain. It indicates that the specific anatomical site of the cellulitis is not documented or is unknown.

Apply this code when the medical record clearly states a diagnosis of cellulitis but provides no further detail regarding the affected body region. This is appropriate when the provider's documentation is limited to "cellulitis" without specifying a location (e.g., leg, arm, face).

• Avoid using this code if a more specific anatomical site of cellulitis is documented; always code to the highest level of specificity.
• Query the provider for clarification on the anatomical site if possible to allow for more precise coding (e.g., L03.113 for cellulitis of the right lower limb).
• Consider co-occurring conditions like abscess (L02.-) or underlying skin conditions that may predispose to cellulitis.
