Unstable burst fracture of second lumbar vertebra, sequela

This code signifies a past, resolved unstable burst fracture of the second lumbar vertebra (L2) that is now causing residual effects or complications. An unstable burst fracture involves significant damage to the vertebral body, often with retropulsion of bone fragments into the spinal canal, and "sequela" indicates that the initial injury has healed but left lasting consequences. These lasting effects could include chronic pain, neurological deficits, or spinal deformity.

Apply this code when a patient presents with ongoing symptoms or conditions directly attributable to a previously sustained and treated unstable burst fracture of L2. This is appropriate for follow-up encounters where the primary focus is managing the long-term complications of the old fracture, rather than the acute injury itself. Examples include chronic radiculopathy, persistent back pain, or post-laminectomy syndrome stemming from the L2 fracture.

• Always use this code as a secondary diagnosis, following the code for the specific sequela being treated (e.g., chronic pain, nerve compression).
• Ensure documentation clearly links the current condition to the prior L2 unstable burst fracture.
• Do not use this code for the initial acute injury or for subsequent fractures at the same site; those require acute fracture codes.
