About T84.038
T84.038 is the ICD-10-CM diagnosis code for mechanical loosening of other 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 T84.03, choose T84.038 (other internal prosthetic joint) only when documentation doesn't support a more specific option: internal right hip prosthetic joint (T84.030), internal left hip prosthetic joint (T84.031), internal right knee prosthetic joint (T84.032), internal left knee prosthetic joint (T84.033) and unspecified internal prosthetic joint (T84.039).
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.
Use an additional code to identify the joint (Z96.6-).
It has been part of ICD-10-CM since the code set took effect on October 1, 2015 and hasn't changed since.
