Displacement of internal fixation device of vertebrae, subs

This code describes a situation where an internal fixation device, such as a rod, screw, or plate, that was surgically implanted to stabilize the vertebrae has shifted from its intended position. This displacement can lead to pain, instability, or neurological symptoms.

Use this code for follow-up encounters where a patient is being evaluated or treated for a previously diagnosed displacement of a vertebral internal fixation device. This includes visits for symptom management, further diagnostic imaging, or planning for revision surgery.

• Ensure documentation clearly states "displacement" and specifies the "vertebrae" as the affected site.
• The 7th character "D" indicates a subsequent encounter, meaning the patient is receiving routine care during the healing or recovery phase.
• Do not use this code for initial encounters where the displacement is first diagnosed; for those, use the appropriate 7th character "A".
