Quadriplegia, C1-C4 complete

This code signifies a complete loss of motor and sensory function in all four limbs and the torso, resulting from a spinal cord injury at the C1-C4 vertebral levels. This severe neurological impairment affects breathing, bowel, and bladder control, and typically requires extensive medical support.

Apply this code when documentation clearly indicates a complete quadriplegia due to a C1-C4 spinal cord lesion. This is typically seen in cases of traumatic spinal cord injury, but can also result from other etiologies like tumors or vascular events affecting the high cervical spine. The "complete" designation implies no motor or sensory function below the level of injury.

• Ensure documentation specifies "complete" quadriplegia; differentiate from incomplete quadriplegia.
• Verify the exact cervical level of the lesion (C1-C4) is explicitly stated in the medical record.
• Always sequence this code after the underlying cause of the spinal cord injury (e.g., fracture, dislocation).
