About T88
T88 is the ICD-10-CM diagnosis code for other complications of surgical and medical care, not elsewhere classified. It belongs to block T80-T88 (complications of surgical and medical care, not elsewhere classified) 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 10 subcodes must be used instead.
To report this condition, pick the subcode that matches the documentation: T88.0 (immunization), T88.1 (classified), T88.2 (anesthesia), T88.3 (anesthesia), T88.4 (intubation), T88.5 (anesthesia), T88.6 (administered), T88.7 (medicament) and 2 more.
The conditions in its Excludes2 note aren't part of T88, but may be coded alongside it if the patient has both: complication following infusion, transfusion and therapeutic injection (T80.-), complication following procedure NEC (T81.-), complications of anesthesia in labor and delivery (O74.-), complications of anesthesia in pregnancy (O29.-) and 6 more.
It has been part of ICD-10-CM since the code set took effect on October 1, 2015 and hasn't changed since.
