Unsp fb in esophagus causing compression of trachea, sequela

This code signifies a long-term or late effect resulting from an unspecified foreign object previously lodged in the esophagus, which at some point caused pressure on the trachea. The initial acute event has resolved, but the patient is now experiencing residual symptoms or complications directly attributable to that past esophageal foreign body and its tracheal compression.

This code is appropriate when documenting a patient presenting with chronic respiratory issues, dysphagia, or other persistent symptoms that are definitively linked to a historical episode of an esophageal foreign body causing tracheal compression. It should be used when the original foreign body has been removed or passed, but its sequelae are still being managed.

• Always sequence this code after the code for the specific sequela being treated (e.g., chronic cough, tracheal stenosis).
• Ensure documentation clearly links the current condition to the past esophageal foreign body and tracheal compression.
• Do not use this code for acute foreign body ingestions; those require codes from the T18.100 series without the "S" seventh character.
