Mechanical complication of nervous system device, implant, and graft

This code signifies a malfunction or adverse event related to an implanted device, graft, or prosthesis within the nervous system. This includes issues like displacement, breakage, or leakage of neurostimulators, shunts, or other neurological implants, leading to symptoms or requiring intervention.

Use this code when documentation clearly indicates a mechanical failure or complication of a nervous system device, such as a fractured spinal cord stimulator lead, a dislodged ventriculoperitoneal shunt, or a leaking intrathecal pump. This code is appropriate when the complication is directly attributable to the device itself, rather than an infection or other biological response.

• Always code the specific nature of the mechanical complication (e.g., fracture, displacement) if known and documented.
• Sequence this code as a secondary diagnosis when the primary reason for the encounter is the management of the complication.
• Ensure documentation specifies the type of nervous system device involved and the exact nature of its mechanical failure.
