About Y65.1
Y65.1 is the ICD-10-CM diagnosis code for wrong fluid used in infusion. It belongs to category Y65 (other misadventures during surgical and medical care), block Y62-Y69 (misadventures to patients during surgical and medical care) and chapter 20 (external causes of morbidity). It is billable, so it can be reported on its own for dates of service from October 1, 2026 through September 30, 2027.
Within Y65 (other misadventures during surgical and medical care), Y65.1 is specifically for wrong fluid used in infusion. Related codes cover Mismatched blood in transfusion (Y65.0), failure in suture or ligature during surgical operation (Y65.2), endotracheal tube wrongly placed during anesthetic procedure (Y65.3), failure to introduce or to remove other tube or instrument (Y65.4), Performance of wrong procedure (operation) (Y65.5) and other specified misadventures during surgical and medical care (Y65.8).
It is not a CC or MCC, so as a secondary diagnosis it doesn't change the MS-DRG severity level.
It has been part of ICD-10-CM since the code set took effect on October 1, 2015 and hasn't changed since.
Before ICD-10, this condition was coded in ICD-9-CM as E876.1 (wrong fluid in infusion).
