About T84
T84 is the ICD-10-CM diagnosis code for complications of internal orthopedic prosthetic devices, implants and grafts. 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: T84.0 (prosthesis), T84.1 (limb), T84.2 (bones), T84.3 (grafts), T84.4 (grafts), T84.5 (prosthesis), T84.6 (device), T84.7 (grafts) and 2 more.
The conditions in its Excludes2 note aren't part of T84, but may be coded alongside it if the patient has both: failure and rejection of transplanted organs and tissues (T86.-) and fracture of bone following insertion of orthopedic implant, joint prosthesis or bone plate (M96.6).
It has been part of ICD-10-CM since the code set took effect on October 1, 2015 and hasn't changed since.
