Breakdown (mechanical) of int fix of vertebrae, subs

This code signifies a mechanical failure of an internal fixation device, such as rods, screws, or plates, that was surgically implanted to stabilize the spine. This breakdown implies a structural compromise of the hardware itself, rather than an infection or displacement.

Apply this code when a patient presents for follow-up care, evaluation, or treatment related to a previously identified mechanical breakdown of spinal fixation hardware. This includes scenarios where the patient is experiencing new or worsening symptoms directly attributable to the device failure.

• Ensure documentation clearly states "mechanical breakdown" or similar terminology indicating a structural failure of the device.
• This code is for a subsequent encounter, meaning the initial problem has already been identified. For initial encounters, a different seventh character would be used.
• Always code the underlying spinal condition or reason for the original fixation separately, if applicable.
