Superficial frostbite of neck, sequela

This code indicates a long-term complication or late effect resulting from a superficial frostbite injury to the neck. It signifies that the initial frostbite has resolved, but the patient continues to experience residual issues directly attributable to that past injury, such as scarring, altered sensation, or chronic pain.

Apply this code when documenting a patient presenting with a current condition that is a direct consequence of a previously sustained superficial frostbite of the neck. This would include follow-up visits for persistent symptoms or complications after the acute phase of the frostbite has passed.

• Always use this code as a secondary diagnosis, following the code for the specific sequela (e.g., scar, neuralgia).
• Ensure documentation clearly links the current condition to the past superficial frostbite of the neck.
• Do not use this code for acute frostbite; use the appropriate T33.1XXA or T33.1XXD codes for initial or subsequent encounters.
