Acute lymphangitis of right finger

This code describes an acute bacterial infection of the lymphatic vessels in the right finger, typically presenting as red streaks extending proximally from an infection site. It signifies an inflammatory process within the lymphatic system, often a complication of a localized skin infection.

Apply this code when documentation clearly indicates acute inflammation of the lymphatic vessels specifically located in the right finger. This diagnosis is supported by findings such as red streaking, tenderness, and swelling along the lymphatic drainage pathways originating from the right finger.

• Ensure documentation specifies "acute" and precisely identifies the "right finger" as the affected site.
• Code any underlying infection (e.g., cellulitis, abscess) that caused the lymphangitis as a primary diagnosis, with this code as a secondary diagnosis.
• Differentiate from chronic lymphangitis or lymphadenitis, which involve different anatomical structures or chronicity.
