Cellulitis of unspecified part of limb

This code signifies an acute, spreading bacterial infection of the skin and subcutaneous tissues of an unspecified limb. It is characterized by localized redness, warmth, swelling, and pain, without a more specific anatomical site documented.

Apply this code when the medical record clearly indicates cellulitis affecting a limb, but the specific location (e.g., arm, leg, hand, foot) is not documented or is unknown. Documentation should support the diagnosis of cellulitis, such as physical exam findings and clinical assessment.

• Avoid using this code if a more specific anatomical site of cellulitis on the limb is documented (e.g., L03.111 for right upper limb).
• Always seek clarification from the provider if the limb laterality or specific site is unclear to allow for more precise coding.
• Consider additional codes for any associated complications, such as abscess (L02.-) or sepsis (A40-A41).
