Corrosion of third degree of right toe(s) (nail), subs

This code signifies a severe chemical injury to the right toe(s), including the nail, that has resulted in full-thickness tissue destruction. This type of injury involves damage through all layers of the skin and potentially underlying structures, indicating a significant and deep wound caused by corrosive substances.

Apply this code when documenting follow-up care for a patient who previously sustained a third-degree corrosion to their right toe(s). This includes encounters for wound care, debridement, skin grafting, or monitoring of healing after the initial treatment phase. It is appropriate for any encounter subsequent to the initial treatment of the corrosion.

• Ensure documentation clearly specifies "corrosion" (chemical burn) rather than a thermal burn.
• Confirm the injury location is the right toe(s) and the depth is third-degree.
• The "D" seventh character indicates a subsequent encounter, meaning the patient is receiving routine care during the healing or recovery phase.
