0.000What This Code Means
Congenital nonprogressive ataxia is a condition present from birth that affects balance and coordination but does not worsen over time.
Coding Tips
- •Confirm the nonprogressive nature is documented to distinguish from progressive ataxias
- •Document the specific type if identified (e.g., Joubert syndrome, pontocerebellar hypoplasia)
Clinical Significance
Congenital nonprogressive ataxia represents a lifelong neurological condition present from birth that affects coordination and balance but remains stable over time. While nonprogressive, it still requires ongoing rehabilitation, adaptive equipment, and monitoring for associated conditions, making accurate capture important for resource allocation.
Documentation Requirements
- ✓Documentation confirming condition is present from birth (congenital)
- ✓Evidence that ataxia is nonprogressive (stable over time, not worsening)
- ✓Neurological examination findings documenting cerebellar signs
- ✓Brain imaging (MRI) findings if available (cerebellar hypoplasia, etc.)
- ✓Specific syndrome if identified (Joubert syndrome, pontocerebellar hypoplasia)
- ✓Current functional status and therapy needs
