Acute lymphangitis of other sites

This code signifies an acute bacterial infection of the lymphatic vessels, characterized by red streaks extending from an infection site towards regional lymph nodes. It indicates inflammation of the lymphatic system, typically presenting with pain, tenderness, and fever.

Apply this code when documentation specifies acute lymphangitis affecting any body site other than the face, trunk, or limbs. This diagnosis is supported by physician notes detailing the characteristic red streaking, tenderness, and systemic symptoms in an unspecified or "other" anatomical location.

• Ensure the documentation clearly states "acute" and specifies a site not covered by more specific lymphangitis codes.
• Always code the underlying infection (e.g., cellulitis, wound infection) first, as lymphangitis is often a complication.
• Avoid using this code if a more specific anatomical site (e.g., L03.11 for limb, L03.21 for face) is documented.
