Breakdown (mechanical) of muscle and tendon graft, init

This code signifies a mechanical failure of a muscle or tendon graft, meaning the graft itself has physically broken down or ruptured. This breakdown is not due to infection, rejection, or a healing complication, but rather a structural failure of the grafted tissue.

Apply this code when a patient presents with symptoms directly related to the structural failure of a previously implanted muscle or tendon graft. This is appropriate for the initial visit where the mechanical breakdown is diagnosed or first addressed.

• Ensure documentation clearly specifies a mechanical breakdown, differentiating it from other graft complications.
• Confirm this is the initial encounter for the specific breakdown event. Subsequent encounters would use a different seventh character.
• Always code the underlying reason for the original graft if still relevant and documented.
