Frostbite with tissue necrosis of neck, sequela

This code signifies a long-term complication or late effect resulting from frostbite that caused tissue death in the neck region. It indicates that the patient is presenting for treatment or evaluation of issues directly attributable to this past injury, such as scarring, chronic pain, or functional impairment.

Use this code when documenting follow-up care for a patient who previously sustained frostbite with tissue necrosis of the neck, and the current encounter addresses a residual condition or sequela of that injury. This applies to situations where the acute frostbite has resolved, but its lasting effects are being managed.

• Always sequence this code after the code for the specific sequela being treated (e.g., scar, chronic pain).
• Ensure documentation clearly links the current condition to the previous frostbite injury of the neck.
• Do not use for initial or acute frostbite encounters; those require acute frostbite codes.
