Foreign body in mouth, sequela

This code signifies a long-term or late-developing complication resulting from a foreign body that was previously lodged in the mouth. It indicates that the initial foreign body event has resolved, but its lasting effects are now being addressed.

Apply this code when a patient presents with a current condition directly attributable to a foreign body that was previously in their mouth. Examples include chronic inflammation, scarring, or nerve damage that developed after the foreign body was removed. Do not use for acute foreign body encounters.

• Requires a seventh character "S" for sequela, indicating a complication or condition that is the late effect of an earlier injury or illness.
• Always sequence this code after the code(s) for the specific sequela being treated (e.g., chronic ulcer, scar formation).
• Ensure documentation clearly links the current condition to a past foreign body in the mouth.
