About Y65

Y65 is the ICD-10-CM diagnosis code for other misadventures during surgical and medical care. It belongs to block Y62-Y69 (misadventures to patients during surgical and medical care) and chapter 20 (external causes of morbidity). It is a header code, so it can't be reported by itself; one of its 7 subcodes must be used instead.

To report this condition, pick the subcode that matches the documentation: Y65.0 (transfusion), Y65.1 (infusion), Y65.2 (operation), Y65.3 (procedure), Y65.4 (instrument), Y65.5 ((operation)) and Y65.8 (care).

It has been part of ICD-10-CM since the code set took effect on October 1, 2015 and hasn't changed since.
