What This Code Means

Paralysis of all four limbs (both arms and both legs) where the specific spinal cord level of injury is not documented or specified.

Coding Tips

•Query the provider for the cervical spinal cord level (C1-C4 or C5-C7) if not documented, as more specific codes provide better clinical detail
•This unspecified code should only be used when the level of injury cannot be determined

Clinical Significance

Unspecified quadriplegia indicates paralysis of all four limbs without specification of the cervical spinal cord level. This is among the most resource-intensive conditions in healthcare, requiring 24-hour assistance, specialized equipment, respiratory support, and management of numerous complications. Accurate capture is essential as it carries the highest RAF weight among paralytic conditions in V24. Provider query for the cervical level should be pursued.

Documentation Requirements

✓Documentation of quadriplegia (paralysis of all four extremities)
✓Underlying etiology (spinal cord injury, tumor, vascular event, etc.)
✓Functional status and level of independence
✓Respiratory status and need for ventilatory support
✓Bladder and bowel management
✓Skin integrity monitoring
✓Equipment needs (power wheelchair, environmental controls)
✓Active management plan with specialist involvement
