Superficial frostbite of thorax, subsequent encounter

This code signifies a superficial cold-induced injury to the chest wall, characterized by skin blanching, numbness, and potential tingling, without blistering or tissue loss. It indicates that the patient is receiving follow-up care for a previously diagnosed episode of superficial frostbite affecting the thorax.

Apply this code when a patient presents for ongoing management, monitoring, or treatment of superficial frostbite of the chest, after the initial encounter for the injury. This includes visits for wound care, assessment of healing, or evaluation of persistent symptoms.

• Ensure documentation specifies "superficial" frostbite and the "thorax" as the affected body region.
• The "D" seventh character indicates a subsequent encounter, meaning the patient is receiving routine care during the healing or recovery phase.
• Do not use for initial treatment of the frostbite; refer to the appropriate "A" (initial encounter) seventh character.
