What This Code Means

A birth defect where the spine doesn't close properly in the upper back area, without fluid buildup in the brain.

Coding Tips

•Verify that hydrocephalus is not present; if present, use Q05.1 instead
•Ensure documentation specifies thoracic location to differentiate from cervical or lumbar spina bifida

Clinical Significance

Thoracic spina bifida without hydrocephalus affects the upper/middle back region and can significantly impact respiratory function, posture, and mobility. This location often presents with paraplegia and requires comprehensive multidisciplinary management including orthopedic, neurologic, and pulmonary care.

Documentation Requirements

✓Confirmation of thoracic spine involvement (T1-T12)
✓Absence of hydrocephalus documented
✓Neurological deficit assessment including motor/sensory function
✓Respiratory function evaluation and capacity testing
✓Spinal deformity assessment (scoliosis, kyphosis)
✓Bladder and bowel function evaluation
✓Mobility status and assistive device needs
✓History of surgical interventions and outcomes
