Breakdown of bone devices, implants and grafts, sequela

This code signifies a long-term complication arising from the mechanical failure of a bone device, implant, or graft, excluding internal joint prostheses, spinal fusion devices, and other specified orthopedic devices. This breakdown can manifest as fracture, loosening, or displacement of the implanted material, occurring after the initial healing phase of the original procedure.

Apply this code when documenting a patient presenting with symptoms or findings directly attributable to the mechanical failure of a previously implanted bone device, such as a plate, screw, or bone graft, where the failure is a sequela. This includes situations where the device has fractured, migrated, or become loose months or years after initial placement.

• Requires an additional code to specify the exact nature of the mechanical breakdown (e.g., M96.61 for fracture of orthopedic internal prosthetic device).
• Use this code for sequela of mechanical breakdown, indicating a late effect rather than an acute complication.
• Distinguish from codes for infection or other non-mechanical complications of bone devices.
