Breakdown of bone devices, implants and grafts, init

This code signifies a mechanical failure of a bone-related device, implant, or graft that is not a joint prosthesis or internal fixation device. This breakdown means the device itself has fractured, loosened, or otherwise failed structurally, rather than an infection or other complication. This is for the initial encounter where the breakdown is identified and treated.

Use this code when a patient presents with symptoms directly attributable to the mechanical failure of a bone stimulator, allograft, xenograft, or other non-joint, non-fixation bone device. This applies to the first time the patient seeks medical attention for this specific mechanical issue. Examples include a fractured bone graft or a malfunctioning bone growth stimulator.

• Ensure the documentation clearly specifies a mechanical breakdown, not an infection or other complication.
• Verify that the device in question is not a joint prosthesis (e.g., hip, knee) or an internal fixation device (e.g., plate, screw), as those have separate codes.
• Confirm this is the initial encounter for the specific mechanical breakdown; subsequent encounters would use the appropriate subsequent encounter or sequela codes.
