Frostbite with tissue necrosis of oth part of head, sequela

This code signifies a past episode of frostbite affecting a non-specified area of the head (excluding eye and ear) that resulted in permanent tissue damage or loss. It indicates that the patient is currently experiencing long-term effects or complications stemming from this historical frostbite injury.

Use this code when documenting a patient presenting with residual issues, such as scarring, chronic pain, or functional impairment, directly attributable to a previous frostbite injury to the head. This applies when the acute frostbite event has resolved, but its lasting consequences are still being managed.

• Requires a seventh character "S" to indicate sequela, meaning the late effects of the initial injury.
• Do not use for acute frostbite; this code is exclusively for chronic, residual conditions.
• Always code the specific sequela (e.g., scar, chronic pain) first, followed by this code as a secondary diagnosis.
