Corrosion of third degree of chest wall, subs encntr

This code signifies a third-degree chemical burn (corrosion) affecting the chest wall, specifically when the patient is receiving follow-up care for this injury. A third-degree burn involves full-thickness destruction of the skin and underlying tissue.

Apply this code for patients presenting for subsequent treatment, such as wound care, debridement, skin grafting, or management of complications, related to a third-degree chemical burn of the chest wall. This code is appropriate after the initial encounter for the injury has concluded.

• Ensure the documentation clearly specifies "third degree" and "corrosion" (chemical burn) of the chest wall.
• The "D" seventh character indicates 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; refer to codes with an "A" seventh character for the initial encounter.
