Superficial frostbite of left ear, initial encounter

This code signifies a mild, non-blistering cold injury affecting the outer surface of the patient's left ear. The damage is limited to the epidermis and potentially the superficial dermis, without tissue loss or deep involvement. It represents the first time this specific frostbite injury is being treated.

Apply this code for patients presenting with a left ear that is numb, white, or waxy in appearance, but without blistering or hardening of the tissue, following exposure to freezing temperatures. This is appropriate for the initial medical evaluation and treatment of such an injury.

• Ensure documentation clearly specifies "superficial" and "left ear" to support this code.
• Verify that the encounter is indeed the initial treatment for this specific frostbite episode.
• Do not use if blistering, tissue necrosis, or deeper involvement of the ear is documented; a more severe frostbite code would be appropriate.
