Frostbite with tissue necrosis of nose, subsequent encounter

This code signifies a frostbite injury to the nose that has progressed to tissue death (necrosis). It indicates that the patient is receiving follow-up care for this specific injury, rather than the initial treatment.

Apply this code when a patient presents for ongoing management, wound care, or evaluation of a necrotic frostbite injury affecting the nose. This includes scenarios where the patient is seen for debridement, infection control, or assessment of healing after the initial frostbite event.

• Ensure documentation clearly specifies the nose as the affected body part and confirms tissue necrosis.
• The "D" in the seventh character indicates a subsequent encounter, meaning the patient is receiving routine care during the healing or recovery phase.
• Do not use this code for initial treatment of the frostbite or for sequelae (late effects) once the acute phase has passed.
