About T86.9
T86.9 is the ICD-10-CM diagnosis code for complication of unspecified transplanted organ and tissue. It belongs to category T86 (complications of transplanted organs and tissue), 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 5 subcodes must be used instead.
Within T86, choose T86.9 (Complication of unspecified transplanted organ and tissue) only when documentation doesn't support a more specific option: complications of bone marrow transplant (T86.0), complications of kidney transplant (T86.1), complications of heart transplant (T86.2), complications of heart-lung transplant (T86.3), complications of liver transplant (T86.4), complications of stem cell transplant (T86.5) and complications of other transplanted organs and tissues (T86.8).
To report this condition, pick the subcode that matches the documentation: T86.90 (tissue), T86.91 (rejection), T86.92 (failure), T86.93 (infection) and T86.99 (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.
