Acute lymphangitis of left finger

This code signifies an acute bacterial infection of the lymphatic vessels in the left finger, typically presenting as red streaks extending from an infection site towards the regional lymph nodes. It is characterized by inflammation and swelling of the lymphatic channels, often accompanied by pain, fever, and malaise.

Apply this code when documentation clearly indicates acute lymphangitis affecting the left finger. This diagnosis is supported by findings such as a red, tender streak originating from a wound or infection on the left finger, along with systemic signs of infection.

• Ensure documentation specifies "acute" and the laterality as "left finger" to support this specific code.
• Do not confuse with cellulitis, though they can co-occur; lymphangitis specifically involves the lymphatic vessels.
• Consider coding an underlying infection (e.g., wound infection, abscess) as a primary diagnosis if it is the source of the lymphangitis.
