Corrosion of third degree of left foot, subsequent encounter

This diagnosis code indicates a severe burn injury affecting the left foot, characterized by full-thickness tissue destruction. This type of corrosion extends through all layers of the skin and often involves underlying tissues, requiring significant medical intervention.

Apply this code when documenting follow-up care for a patient with a third-degree corrosion of the left foot. This includes subsequent visits for wound care, debridement, skin grafting, or management of complications after the initial treatment of the burn.

• Ensure documentation clearly specifies "left foot" and "third degree" corrosion.
• The "D" seventh character signifies a subsequent encounter, meaning the patient is receiving routine care during the healing or recovery phase.
• Do not use this code for initial treatment of the burn; a different seventh character would be appropriate for the initial encounter.
