About T84.49
T84.49 is the ICD-10-CM diagnosis code for other mechanical complication of other internal orthopedic devices, implants and grafts. It belongs to category T84 (complications of internal orthopedic prosthetic devices, implants and grafts), 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 2 subcodes must be used instead.
Within T84.4, choose T84.49 (Other mechanical complication of other internal orthopedic devices, implants and grafts) only when documentation doesn't support a more specific option: breakdown (mechanical) of other internal orthopedic devices, implants and grafts (T84.41) and displacement of other internal orthopedic devices, implants and grafts (T84.42).
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.
