T84.9Unspecified complication of internal orthopedic prosthetic device, implant and graft

T84.9 is the ICD-10-CM diagnosis code for unspecified complication of internal orthopedic prosthetic device, implant and graft. 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 3 subcodes must be used instead.

Within T84, choose T84.9 (Unspecified complication of internal orthopedic prosthetic device, implant and graft) only when documentation doesn't support a more specific option: mechanical complication of internal joint prosthesis (T84.0), mechanical complication of internal fixation device of bones of limb (T84.1), mechanical complication of internal fixation device of other bones (T84.2), mechanical complication of other bone devices, implants and grafts (T84.3), mechanical complication of other internal orthopedic devices, implants and grafts (T84.4), infection and inflammatory reaction due to internal joint prosthesis (T84.5), infection and inflammatory reaction due to internal fixation device (T84.6), infection and inflammatory reaction due to other internal orthopedic prosthetic devices, implants and grafts (T84.7) and 1 more.

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.
