Unspecified open wound of nose, sequela

This code signifies an open wound of the nose where the specific nature of the wound (e.g., laceration, puncture, avulsion) is not documented. It indicates that the injury is a late effect or complication of an initial wound that has healed, but residual problems persist.

Use this code when documentation clearly indicates a sequela (late effect) of an unspecified open wound to the nose. This applies when the initial acute injury has resolved, but the patient presents with ongoing issues directly attributable to the original wound, and the type of open wound was never specified. Documentation should explicitly state "sequela" or "late effect" and mention the nose as the affected anatomical site.

• Always sequence this sequela code after the primary code describing the specific late effect (e.g., scar, deformity).
• Avoid using this code if the specific type of open wound (e.g., laceration, puncture) is documented; instead, use the appropriate specific sequela code.
• Ensure the documentation supports that the current condition is a direct result of a previous open wound, not an acute injury.
