Acute lymphangitis of right lower limb

This code signifies an acute bacterial infection of the lymphatic vessels in the right lower extremity, typically presenting as red streaks extending from an infection site towards regional lymph nodes. It is often a complication of a skin infection, such as cellulitis or an abscess, and indicates inflammation of the lymphatic system.

Use this code when documentation clearly states acute lymphangitis affecting the patient's right lower limb. This diagnosis is supported by findings such as red streaking, tenderness along lymphatic pathways, and often fever or malaise, in the absence of chronic or recurrent conditions.

• Ensure documentation specifies "acute" and "right lower limb" to accurately assign this code.
• Frequently co-occurs with codes for the underlying infection (e.g., cellulitis, abscess); sequence the underlying infection first if it is the primary reason for the encounter.
• Differentiate from cellulitis alone; lymphangitis involves the lymphatic vessels, not just the subcutaneous tissue.
