About T28.412

T28.412 is the ICD-10-CM diagnosis code for burn of left ear drum. It belongs to category T28 (burn and corrosion of other internal organs), block T26-T28 (burns and corrosions confined to eye and internal organs) 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 T28.41 (burn of ear drum), T28.412 is specifically for burn of left ear drum. Related codes cover right ear drum (T28.411) and unspecified ear drum (T28.419).
