Breakdown of bone devices, implants and grafts, subs

This code signifies a mechanical failure or malfunction of a bone-related device, implant, or graft that is not specifically classified elsewhere. This breakdown occurs after the initial treatment phase, indicating a complication with the hardware itself rather than a biological failure of the bone.

Apply this code when a patient presents for follow-up care due to a mechanical issue with an orthopedic implant, such as a fractured plate, loosened screw, or dislodged bone graft. This includes scenarios where the device itself has physically broken or become unstable, requiring further intervention or monitoring.

• Ensure the documentation clearly states a mechanical breakdown of the device, not an infection or nonunion.
• Confirm the encounter is for subsequent care related to the breakdown, as indicated by the 7th character "D."
• If the specific device type is known and has a more precise code (e.g., T84.010D for internal fixation device of bone of arm), use that code instead.
