About T17.2

T17.2 is the ICD-10-CM diagnosis code for foreign body in pharynx. It belongs to category T17 (foreign body in respiratory 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 4 subcodes must be used instead.

Within T17 (foreign body in respiratory tract), T17.2 is specifically for foreign body in pharynx. Related codes cover nasal sinus (T17.0), nostril (T17.1), larynx (T17.3), trachea (T17.4), bronchus (T17.5), other parts of respiratory tract (T17.8) and part unspecified (T17.9).

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.
