Injury to lumbosacral plexus

This code signifies damage or trauma to the lumbosacral plexus, a network of nerves originating from the lumbar and sacral spinal cord segments. Such injuries can result in motor weakness, sensory deficits, and pain in the lower extremities, pelvis, and perineum.

Apply this code when documentation clearly indicates a direct injury to the lumbosacral plexus, such as from a fracture, penetrating wound, or severe compression. Supporting documentation should specify the mechanism of injury and the neurological deficits attributable to lumbosacral plexus involvement.

• Differentiate from more generalized nerve root injuries (radiculopathies) or peripheral nerve injuries affecting individual nerves distal to the plexus.
• Ensure the documentation specifies "lumbosacral plexus" rather than just "lumbar nerves" or "sacral nerves" to support this specific code.
• Consider sequencing this code after the primary injury (e.g., fracture) if the plexus injury is a direct consequence.
