Mech compl of internal fixation device of vertebrae, sequela

This code signifies a long-term or residual issue arising from a mechanical problem with an internal fixation device previously implanted in the vertebrae. It indicates that the initial complication, such as loosening, displacement, or fracture of the device, has resolved but left behind a lasting effect or condition. This could manifest as chronic pain, nerve impingement, or functional impairment directly attributable to the past mechanical complication.

Use this code when documenting a patient presenting with a current condition or symptom that is a direct consequence of a resolved "other mechanical complication" of a vertebral internal fixation device. This applies to follow-up encounters where the acute complication itself is no longer active, but its lingering impact is being addressed. Examples include chronic radiculopathy due to nerve damage from a previously displaced screw, or persistent instability after a device fracture has been managed.

• Requires a seventh character 'S' for sequela, indicating a late effect.
• Do not use for active or acute mechanical complications; those would use the 'A' or 'D' seventh characters.
• Always code the specific sequela (e.g., chronic pain, nerve damage) first, followed by this code as a secondary diagnosis to explain the etiology.
