Subluxation of L4/L5 lumbar vertebra, sequela

This code signifies a chronic or late effect of a partial dislocation of the L4/L5 lumbar vertebrae. It indicates that the vertebral bodies are no longer perfectly aligned, but the articular surfaces remain in partial contact, and the patient is experiencing ongoing symptoms or conditions directly resulting from this past subluxation.

Use this code when documenting a patient presenting with persistent pain, neurological deficits, or other long-term complications that are directly attributable to a previously diagnosed subluxation of the L4/L5 segment. This applies to situations where the initial injury has resolved, but its lasting effects are being treated.

• Always use this code as a secondary diagnosis, following the code for the specific sequela (e.g., chronic pain, radiculopathy).
• Ensure documentation clearly links the current condition to the prior L4/L5 subluxation.
• The "S" seventh character indicates a sequela, meaning the condition is a late effect of the original injury.
