Acute lymphangitis of left toe

This code signifies an acute bacterial infection of the lymphatic vessels in the left toe. It is characterized by red streaks extending from the site of infection, often accompanied by pain, swelling, and warmth. This condition typically arises from a localized infection, such as a cut or insect bite.

Apply this code when documentation clearly indicates an acute inflammatory process affecting the lymphatic channels specifically within the left toe. Supporting documentation should include physician notes detailing the location (left toe), the acute nature of the infection, and clinical signs consistent with lymphangitis.

• Ensure the documentation specifies "acute" and not chronic lymphangitis, as different codes apply.
• Verify the laterality is precisely documented as "left toe"; codes exist for other sites and unspecified laterality.
• Always code the underlying infection (e.g., cellulitis, wound infection) first, if present, as the primary diagnosis, with lymphangitis as a secondary diagnosis.
