External constriction of nose, sequela

This code signifies a lasting effect or complication resulting from an external constriction injury to the nose. This could include chronic pain, disfigurement, functional impairment (e.g., breathing difficulties), or nerve damage that persists after the initial injury has healed.

Use this code when documenting a current condition that is a direct consequence of a past external constriction injury to the nose. Documentation should clearly link the current sequela to the previous injury and indicate that the acute phase of the constriction has resolved.

• Requires a seventh character "S" to indicate sequela, meaning the initial injury has healed and the current condition is a residual effect.
• Always sequence the sequela code first, followed by codes for the specific manifestation(s) of the sequela (e.g., chronic pain, deformity).
• Ensure documentation specifies the external nature of the constriction to differentiate from internal nasal injuries.
