Unstable burst fracture of first lumbar vertebra, init

This code signifies a severe, unstable fracture of the first lumbar vertebra (L1) where the vertebral body is significantly compressed and fragmented, often with retropulsion of bone fragments into the spinal canal. "Unstable" indicates a high risk of neurological compromise and spinal deformity, while "burst" describes the comminuted nature of the fracture.

Apply this code for patients presenting with a newly diagnosed, closed burst fracture of the L1 vertebra that is deemed unstable by the treating physician. This typically involves high-energy trauma mechanisms such as falls from height or motor vehicle accidents. It is used for the initial treatment phase of the fracture.

• Confirm documentation explicitly states "unstable burst fracture" of L1.
• Verify "closed fracture" status; open fractures have different codes.
• Ensure "initial encounter" is appropriate for the patient's current treatment phase.
