About T80.310

T80.310 is the ICD-10-CM diagnosis code for ABO incompatibility with acute hemolytic transfusion reaction. It belongs to category T80 (complications following infusion, transfusion and therapeutic injection), 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 3 subcodes must be used instead.

Within T80.31 (ABO incompatibility with hemolytic transfusion reaction), T80.310 is specifically for ABO incompatibility with acute hemolytic transfusion reaction. Related codes cover delayed hemolytic transfusion reaction (T80.311) and unspecified (T80.319).

Codes in this range require a 7th character: A for initial encounter, D for subsequent encounter and S for sequela. Use placeholder "X" characters to fill any empty positions before the 7th character.

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

7th character

The appropriate 7th character is to be added to each code from category T80
