Mechanical loosening of internal prosthetic joint, sequela

This code signifies a complication where an internal prosthetic joint, other than those specifically classified elsewhere (e.g., hip, knee), has become loose due to mechanical failure. This loosening can lead to pain, instability, and impaired function of the affected joint. It is a long-term consequence of the initial joint replacement.

Use this code when documenting a patient presenting with symptoms or signs of mechanical loosening of an internal prosthetic joint, such as in the shoulder, ankle, or elbow, that is not a hip or knee. This code is appropriate for follow-up encounters after the initial joint replacement when this specific complication is identified.

• Always assign an additional code for the specific type of prosthetic joint involved (e.g., T84.01- for shoulder, T84.02- for elbow).
• This is a sequela code, indicating a late effect, and should be used for ongoing management of the loosening.
• Do not use this code for acute dislocation or infection of a prosthetic joint, as those have separate specific codes.
