Foreign body in nasal sinus, sequela

This code signifies the long-term or residual effects resulting from a foreign object previously lodged within a nasal sinus. These sequelae can manifest as chronic inflammation, infection, structural damage, or other persistent issues that developed as a consequence of the initial foreign body presence. It indicates that the acute foreign body event has passed, but its impact continues.

This code is appropriate when documenting conditions like chronic sinusitis, nasal polyps, or persistent pain that are directly attributed to a foreign body that was previously removed from or spontaneously expelled from a nasal sinus. It should be used when the patient is presenting for treatment of these lasting complications, not for the initial foreign body removal.

• Always link this sequela code to an external cause code (V00-Y99) if the original foreign body event was due to an external cause.
• Do not use this code for the initial encounter or acute phase of a foreign body in the nasal sinus; use the acute foreign body codes instead.
• Ensure documentation clearly states the causal link between the current condition and the prior foreign body in the nasal sinus.
