About Y84
Y84 is the ICD-10-CM diagnosis code for other medical procedures as the cause of abnormal reaction of the patient, or of later complication, without mention of misadventure at the time of the procedure. It belongs to block Y83-Y84 (surgical and other medical procedures as the cause of abnormal reaction of the patient, or of later complication, without mention of misadventure at the time of the procedure) and chapter 20 (external causes of morbidity). It is a header code, so it can't be reported by itself; one of its 10 subcodes must be used instead.
To report this condition, pick the subcode that matches the documentation: Y84.0 (procedure), Y84.1 (procedure), Y84.2 (procedure), Y84.3 (procedure), Y84.4 (procedure), Y84.5 (procedure), Y84.6 (procedure), Y84.7 (procedure) and 2 more.
It has been part of ICD-10-CM since the code set took effect on October 1, 2015 and hasn't changed since.
