In simple words: This code is for when a medical device implanted inside the body breaks down or malfunctions.This includes things like artificial joints or other implants, and does not include failures specifically mentioned in other codes.

This code classifies the mechanical failure of various internal prosthetic devices, implants, or grafts, excluding those specifically listed elsewhere.It encompasses complications arising from the malfunction or breakage of these medical devices within the body, requiring further investigation and potentially intervention.This code should be used when the specific type of device or implant is not further specified or is not listed under other, more specific codes within the T85 category.

Example 1: A patient with a previously implanted hip prosthesis experiences a mechanical fracture of the device resulting in pain and limited mobility. Code T85.61 is used, along with codes specifying the location and type of fracture., A patient with an implanted cardiac pacemaker experiences a mechanical malfunction leading to irregular heart rhythm. Code T85.61 is used, along with a code to specify the nature of the malfunction., A patient with an implanted intraperitoneal dialysis catheter experiences a mechanical failure leading to leakage. Code T85.61 is used in conjunction with a code for catheter failure.

Detailed documentation should include the type of prosthetic device, implant, or graft; the date of implantation; the date of failure; a description of the mechanical failure; and the clinical findings, such as pain, swelling, or functional impairment.Relevant imaging studies (x-rays, CT scans, etc.) should be documented as well as any treatment provided (e.g., surgical revision, replacement).

** This code is for mechanical complications; do not use it for failure or rejection of transplanted organs or tissues (T86.-).
