Dislocation of L1/L2 lumbar vertebra, initial encounter

This code signifies a complete displacement of the first lumbar vertebra (L1) from its normal articulation with the second lumbar vertebra (L2). This injury involves the disruption of the facet joints and intervertebral disc, leading to instability and potential neurological compromise.

Apply this code for the initial treatment of a patient presenting with a diagnosed L1/L2 lumbar vertebral dislocation. This typically occurs following significant trauma, such as a motor vehicle accident or a fall from a height.

• Ensure documentation clearly specifies the L1/L2 level and confirms a true dislocation, not just a subluxation.
• Verify this is the patient's first encounter for this specific injury; subsequent encounters will require a different seventh character.
• Always code any associated spinal cord injury or neurological deficits separately.
