Food in bronchus causing other injury, sequela

This code signifies a long-term or late-appearing complication resulting from a foreign body (specifically food) having been aspirated into the bronchus. The initial aspiration event has already occurred and resolved, but its lasting effects, such as chronic inflammation, bronchiectasis, or persistent respiratory compromise, are now being addressed.

Apply this code when documenting a patient presenting with a current condition directly attributable to a past episode of food aspiration into the bronchus. This is appropriate for follow-up encounters addressing chronic respiratory issues that developed as a consequence of the initial aspiration, rather than the acute aspiration event itself.

• Requires a seventh character of "S" for sequela, indicating a complication or condition that arises as a direct result of an earlier injury or disease.
• Do not use for acute aspiration events; those require codes from the T17.52 series without the "S" seventh character or with an "A" for initial encounter.
• Always sequence this code after the code(s) for the specific manifestation(s) of the sequela (e.g., chronic bronchitis, bronchiectasis).
