About T86

T86 is the ICD-10-CM diagnosis code for complications of transplanted organs and tissue. 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 8 subcodes must be used instead.

To report this condition, pick the subcode that matches the documentation: T86.0 (transplant), T86.1 (transplant), T86.2 (transplant), T86.3 (transplant), T86.4 (transplant), T86.5 (transplant), T86.8 (tissues) and T86.9 (tissue).

Use an additional code to identify other transplant complications, such as: graft-versus-host disease (D89.81-), malignancy associated with organ transplant (C80.2) and post-transplant lymphoproliferative disorders (PTLD) (D47.Z1).

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