Dislocation of L3/L4 lumbar vertebra, initial encounter

This code signifies a complete displacement of the third lumbar vertebra (L3) from its normal articulation with the fourth lumbar vertebra (L4). This injury disrupts the spinal column's alignment at this specific level, potentially causing significant pain, neurological deficits, and instability.

Apply this code for initial encounters with patients presenting with a confirmed dislocation between the L3 and L4 vertebrae. This typically occurs due to high-impact trauma such as motor vehicle accidents, falls from heights, or severe sports injuries.

• Ensure documentation clearly specifies "dislocation" and not a subluxation or fracture.
• Verify the specific vertebral levels involved (L3/L4) as other lumbar dislocations have different codes.
• The "A" suffix indicates an initial encounter for active treatment of the injury.
