Frostbite with tissue necrosis of left ear, init encntr

This code signifies a severe cold-induced injury to the left ear, specifically involving tissue death (necrosis). This indicates a full-thickness injury where the tissue has been irreversibly damaged due to freezing.

Apply this code when a patient presents with a confirmed diagnosis of frostbite affecting the left ear, and there is clear documentation of tissue necrosis. This is appropriate for the initial visit for this specific injury, such as in an emergency department or initial clinic consultation.

• Ensure documentation explicitly states "necrosis" or "tissue death" of the left ear due to frostbite.
• Verify the encounter is the initial treatment for this specific frostbite injury.
• Do not use if only superficial frostbite or frostnip is present without necrosis.
