Superficial frostbite of left ankle, subsequent encounter

This code signifies a superficial frostbite injury affecting the left ankle. This type of frostbite involves damage to the outermost layers of skin, characterized by numbness, tingling, and a waxy appearance, without blistering or tissue loss.

This code is appropriate for follow-up encounters where a patient is receiving ongoing treatment or monitoring for a previously diagnosed superficial frostbite of the left ankle. This includes visits for wound care, assessment of healing progress, or management of residual symptoms.

• Ensure documentation clearly specifies "superficial" frostbite and the "left ankle" as the affected site.
• The "D" seventh character indicates a subsequent encounter, meaning the patient is receiving routine care during the healing phase.
• Do not use this code for initial treatment of the frostbite or for sequelae (late effects) once the acute injury has healed.
