Unstable burst fracture of fifth lumbar vertebra, sequela

This code signifies a past, resolved unstable burst fracture of the fifth lumbar vertebra (L5) that continues to cause long-term effects or complications. An unstable burst fracture involves significant comminution and potential compromise of the spinal canal, and "sequela" indicates that the acute injury has healed but residual issues persist. These lasting effects can include chronic pain, neurological deficits, or spinal instability.

Use this code when documenting follow-up care for a patient who previously sustained an unstable burst fracture of L5 and is now presenting with ongoing problems directly attributable to that past injury. This applies to situations where the acute fracture has healed, but the patient experiences chronic pain, radiculopathy, weakness, or other functional limitations stemming from the original trauma. Do not use for the initial acute injury.

• Always use an additional code to specify the nature of the sequela (e.g., chronic pain, neurological deficit).
• Ensure documentation clearly links the current condition to the past unstable burst fracture of L5.
• Verify that the fracture is indeed healed and the current encounter is for residual effects, not active treatment of the acute fracture.
