Superficial frostbite of left hand, subsequent encounter

This code indicates a superficial cold-induced injury to the left hand, characterized by numbness, tingling, and possibly skin discoloration, but without tissue damage extending beyond the epidermis. It signifies that the patient is receiving follow-up care for this frostbite after the initial treatment.

Apply this code when a patient presents for a follow-up visit, such as wound checks, medication refills, or assessment of healing progress, for a previously diagnosed superficial frostbite of the left hand. This includes encounters occurring after the initial treatment phase has concluded.

• Ensure documentation clearly specifies "superficial" frostbite and the "left hand" as the affected site.
• The 7th character "D" is crucial and indicates a subsequent encounter, meaning care after the active treatment of the injury.
• Do not use for initial treatment encounters or for sequelae (late effects) of the frostbite.
