0.000What This Code Means
A birth defect where the spine doesn't close properly at an unspecified location, combined with fluid buildup in the brain (hydrocephalus).
Coding Tips
- •Use this code only when spina bifida with hydrocephalus is confirmed but the specific spinal level is not documented
- •Query the provider for the anatomical location if possible to assign a more specific code
Clinical Significance
This represents a complex congenital malformation combining spina bifida with hydrocephalus, requiring lifelong multidisciplinary care and monitoring. The combination significantly increases morbidity risk and healthcare utilization compared to isolated spina bifida, making accurate documentation crucial for risk adjustment.
Documentation Requirements
- ✓Presence of spina bifida with anatomical location unspecified
- ✓Concurrent hydrocephalus with evidence of increased intracranial pressure
- ✓Neurological deficits or functional impairments
- ✓History of surgical interventions (shunt placement, spinal closure)
- ✓Current management plan and specialist consultations
- ✓Developmental assessments and cognitive function status
- ✓Associated complications (bladder/bowel dysfunction, mobility issues)
- ✓Ongoing rehabilitation needs and therapy requirements
