About T84.018

T84.018 is the ICD-10-CM diagnosis code for broken internal joint prosthesis, other site. 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 T84.01, choose T84.018 (other site) only when documentation doesn't support a more specific option: right hip prosthesis (T84.010), left hip prosthesis (T84.011), right knee prosthesis (T84.012), left knee prosthesis (T84.013) and unspecified site (T84.019).

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.
