About T80.69
T80.69 is the ICD-10-CM diagnosis code for other serum reaction due to other serum. 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 T80.6, choose T80.69 (other serum) only when documentation doesn't support a more specific option: administration of blood and blood products (T80.61) and vaccination (T80.62).
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.

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