Unsp fb in oth prt resp tract causing oth injury, sequela

This code describes a long-term complication or sequela resulting from an unspecified foreign object that was lodged in a part of the respiratory tract other than the larynx, trachea, bronchus, or lung. The foreign body caused an injury, and the patient is now presenting with a residual effect of that injury.

Use this code when documenting a patient presenting for follow-up care or treatment of a chronic condition directly attributable to a past foreign body aspiration event in an unspecified "other" respiratory tract location. This applies when the acute phase of the foreign body removal or initial injury has passed, and the current encounter addresses a lasting consequence.

• Ensure the medical record clearly links the current sequela to a past foreign body aspiration event.
• This code requires a 7th character "S" for sequela, indicating a complication or residual effect of a previous injury.
• Avoid using this code for acute foreign body aspiration; instead, use codes from the T17 category without the "S" seventh character for initial encounters.
