Superficial frostbite of left wrist, subsequent encounter

This code signifies a superficial cold-induced injury to the left wrist, characterized by skin blanching, numbness, and potential tingling, without blistering or tissue loss. It indicates that the patient is receiving follow-up care for this frostbite after the initial treatment.

Apply this code when a patient presents for ongoing management, such as wound care, pain assessment, or monitoring for complications, related to a previously diagnosed superficial frostbite of the left wrist. This includes visits for dressing changes or re-evaluation of the affected area after the initial encounter.

• Ensure documentation specifies "superficial" frostbite and the "left wrist" 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 for initial treatment of the injury or for sequelae (late effects) once the acute phase has passed.
