Mech compl of internal orth devices, implnt and grafts, subs

This code signifies a mechanical issue with an internal orthopedic device, implant, or graft that is not specifically classified elsewhere, occurring during a subsequent encounter for care. It indicates a problem such as loosening, displacement, or fracture of the device itself, rather than a biological complication like infection. The patient is receiving active treatment for this complication.

Apply this code when a patient presents for follow-up care or treatment of a mechanical complication related to an internal orthopedic device, implant, or graft that is not explicitly defined by more specific codes. Examples include a patient returning for evaluation of a suspected loose screw in a bone plate, or a fracture of a previously implanted internal fixation device. This code is appropriate when the encounter is for the ongoing management of the complication.

• Ensure the documentation clearly states the encounter is for active treatment of the mechanical complication, not just routine follow-up.
• Verify that no more specific code exists for the particular type of mechanical complication or the specific device involved.
• Always sequence this code after the primary diagnosis indicating the reason for the encounter, if applicable.
