What This Code Means

A birth defect where the spine doesn't close properly in the lower back area, combined with fluid buildup in the brain (hydrocephalus).

Coding Tips

  • Confirm the spina bifida location is lumbar (lower back) and hydrocephalus is present
  • This is the most common location for spina bifida; distinguish from Q05.7 which excludes hydrocephalus

Clinical Significance

Lumbar spina bifida with hydrocephalus is one of the most common forms of spina bifida, typically associated with significant lower extremity paralysis and neurogenic bladder/bowel dysfunction. The combination with hydrocephalus increases complexity and requires coordinated neurosurgical and urological management.

Documentation Requirements

  • Specific lumbar vertebral levels involved in the defect
  • Hydrocephalus status with current imaging and measurements
  • Lower extremity motor and sensory function assessment
  • Neurogenic bladder and bowel management status
  • Ambulation status and assistive device needs
  • Shunt system details including type and revision history
  • Skin integrity and pressure ulcer risk assessment
  • Educational and developmental milestone documentation
