Mech compl of int orth devices, implnt and grafts, sequela

This code signifies a long-term or late-effect complication arising from a mechanical issue with an internal orthopedic device, implant, or graft, where the specific complication is not otherwise classified. It indicates that the initial mechanical problem has led to a persistent or residual condition requiring ongoing management.

This code is appropriate for documenting conditions such as chronic pain, nerve damage, or persistent functional impairment that are directly attributable to a past mechanical failure (e.g., loosening, displacement, fracture) of an internal orthopedic device. It should be used when the acute phase of the mechanical complication has resolved, but its lasting effects are still present.

• Always sequence this code after the code(s) for the specific sequela (e.g., chronic pain, nerve palsy).
• Ensure documentation clearly links the current condition to a previous mechanical complication of an orthopedic device.
• Avoid using this code for acute or ongoing mechanical complications; those would typically use the non-sequela T84.498A/D codes.
