About T80

T80 is the ICD-10-CM diagnosis code for complications following infusion, transfusion and therapeutic injection. 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: T80.0 (injection), T80.1 (injection), T80.2 (injection), T80.3 (products), T80.4 (products), T80.5 (serum), T80.6 (reactions), T80.8 (injection) and 2 more.

The conditions in its Excludes2 note aren't part of T80, but may be coded alongside it if the patient has both: bone marrow transplant rejection (T86.01), febrile nonhemolytic transfusion reaction (R50.84), fluid overload due to transfusion (E87.71), posttransfusion purpura (D69.51) and 3 more.

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