Frostbite with tissue necrosis of thorax, sequela

This code signifies a long-term complication or residual effect of frostbite that previously affected the chest area, resulting in the death of tissue. It indicates that the tissue necrosis in the thorax is no longer an acute injury but rather a permanent consequence of the initial frostbite exposure.

Use this code when documenting a patient presenting with a current condition directly attributable to a past episode of frostbite to the thorax, where tissue necrosis was a feature. This applies to follow-up encounters for chronic issues such as scarring, persistent pain, or functional impairment stemming from the original tissue damage. It should be used after the acute phase of frostbite treatment has concluded.

• This code is for sequelae only; do not use for acute frostbite.
• Ensure documentation clearly links the current thoracic condition to a previous frostbite event with tissue necrosis.
• Always assign an additional code to specify the exact nature of the sequela (e.g., scar, chronic pain).
