T84.09Other mechanical complication of internal joint prosthesis

T84.09 is the ICD-10-CM diagnosis code for other mechanical complication of internal joint prosthesis. 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 6 subcodes must be used instead.

Within T84.0, choose T84.09 (Other mechanical complication of internal joint prosthesis) only when documentation doesn't support a more specific option: broken internal joint prosthesis (T84.01), dislocation of internal joint prosthesis (T84.02), mechanical loosening of internal prosthetic joint (T84.03), Periprosthetic osteolysis of internal prosthetic joint (T84.05) and wear of articular bearing surface of internal prosthetic joint (T84.06).

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.
