About S27.412

S27.412 is the ICD-10-CM diagnosis code for primary blast injury of bronchus, bilateral. It belongs to category S27 (injury of other and unspecified intrathoracic organs), block S20-S29 (injuries to the thorax) 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 S27.41 (primary blast injury of bronchus), S27.412 is specifically for primary blast injury of bronchus, bilateral. Related codes cover unilateral (S27.411) and unspecified (S27.419).

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.
