Frostbite with tissue necrosis of right ear, sequela

This code signifies a chronic or late effect of frostbite affecting the right ear, specifically characterized by the death of tissue. This necrosis is a permanent consequence of the initial frostbite injury, indicating a long-term complication rather than an acute or initial presentation.

This code is appropriate for encounters where a patient is being treated for the lasting effects of frostbite to the right ear, specifically when tissue death has occurred. This includes follow-up care for reconstructive surgery, management of chronic pain, or addressing functional impairments directly resulting from the necrotic tissue. It should be used after the initial frostbite injury has healed and the sequela is being addressed.

• Assign this code for encounters addressing the long-term complications of frostbite, not the initial injury.
• Ensure documentation clearly specifies "right ear" and "tissue necrosis" as a sequela.
• Do not use this code for acute frostbite or frostbite without tissue necrosis.
