T17.81Gastric contents in other parts of respiratory tract

T17.81 is the ICD-10-CM diagnosis code for gastric contents in other parts of respiratory tract. 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 2 subcodes must be used instead.

Within T17.8, choose T17.81 (Gastric contents in other parts of respiratory tract) only when documentation doesn't support a more specific option: unspecified foreign body in other parts of respiratory tract (T17.80), food in other parts of respiratory tract (T17.82) and other foreign object in other parts of respiratory tract (T17.89).

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.
