T84.059Periprosthetic osteolysis of unspecified internal prosthetic joint

T84.059 is the ICD-10-CM diagnosis code for Periprosthetic osteolysis of unspecified internal prosthetic joint. 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 T84.05, choose T84.059 (unspecified internal prosthetic joint) only when documentation doesn't support a more specific option: internal prosthetic right hip joint (T84.050), internal prosthetic left hip joint (T84.051), internal prosthetic right knee joint (T84.052), internal prosthetic left knee joint (T84.053) and other internal prosthetic joint (T84.058).

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.
