Frostbite w tissue necrosis of left finger(s), init encntr

This code signifies frostbite affecting one or more fingers on the left hand, where the tissue damage is severe enough to cause necrosis (tissue death). It indicates a deep, severe injury resulting from prolonged exposure to freezing temperatures, leading to irreversible cellular damage.

Apply this code for patients presenting with left finger frostbite that has progressed to tissue necrosis, and this is the first time they are being treated for this specific injury. This would be appropriate for initial evaluations in the emergency department or first clinic visit for such a condition.

• Ensure documentation clearly specifies "left" finger(s) and confirms tissue necrosis.
• Verify this is the initial encounter for this specific frostbite injury; subsequent care would use a different encounter character.
• Do not use for superficial frostbite or frostbite without documented tissue necrosis.
