Frostbite with tissue necrosis of nose, sequela

This code signifies a long-term complication or late effect resulting from frostbite that caused tissue death in the nose. It indicates that the initial frostbite injury to the nasal area led to irreversible damage and necrosis, and the patient is now presenting with ongoing issues related to this past event.

Use this code when documenting a patient presenting with a current condition or sequela directly attributable to a previous frostbite injury of the nose that involved tissue necrosis. This applies to situations where the acute frostbite has resolved, but its lasting effects, such as scarring, deformity, or chronic pain, are being addressed.

• Requires a seventh character 'S' for sequela, indicating a late effect.
• Do not use for acute frostbite; this code is for residual conditions after the initial injury has healed.
• Consider additional codes for specific manifestations of the sequela, such as chronic pain or cosmetic deformity, if applicable.
