Oth forn object in resp tract, part unsp cause oth inj, sqla

This code signifies a long-term complication or residual effect stemming from an unspecified foreign object that was previously lodged in an unidentifiable part of the respiratory tract, leading to an injury other than those specifically classified elsewhere. It indicates that the acute phase of the foreign body aspiration has passed, but the patient continues to experience related health issues.

Apply this code when documenting a patient presenting with a chronic condition or sequela directly attributable to a past foreign body aspiration into the respiratory tract, where the exact nature of the foreign object and the specific anatomical location within the respiratory tract are not precisely known. This is appropriate for follow-up encounters addressing persistent symptoms or damage from such an event.

• Always sequence this sequela code after the code for the specific sequela being treated (e.g., chronic bronchitis, stricture).
• Ensure documentation clearly links the current condition to a past foreign body in the respiratory tract, even if details are vague.
• Avoid using this code for acute foreign body aspirations; those require codes from the T17 series without the "S" seventh character.
