About T18.100

T18.100 is the ICD-10-CM diagnosis code for unspecified foreign body in esophagus causing compression of trachea. It belongs to category T18 (foreign body in alimentary tract), block T15-T19 (effects of foreign body entering through natural orifice) and chapter 19 (injury, poisoning and certain other consequences of external causes). It is a header code, so it can't be reported by itself; one of its 3 subcodes must be used instead.

Within T18.10 (unspecified foreign body in esophagus), T18.100 is specifically for unspecified foreign body in esophagus causing compression of trachea. Related codes cover causing other injury (T18.108).

Codes in this range require a 7th character: A for initial encounter, D for subsequent encounter and S for sequela. Use placeholder "X" characters to fill any empty positions before the 7th character.

It has been part of ICD-10-CM since the code set took effect on October 1, 2015 and hasn't changed since.
