0.000What This Code Means
Krabbe disease is a rare inherited metabolic disorder affecting the nervous system where the body cannot properly break down certain fatty substances in nerve cells, leading to progressive neurological deterioration, developmental delays, and loss of function.
Coding Tips
- •Document the age of onset (infantile, late infantile, juvenile, or adult form) as this significantly impacts disease progression
- •Code associated neurological manifestations such as seizures, developmental delay, or spasticity separately if documented
Clinical Significance
Krabbe disease (globoid cell leukodystrophy) is a rapidly progressive lysosomal storage disorder caused by galactosylceramidase deficiency, leading to severe demyelination of the central and peripheral nervous systems. The infantile form is uniformly fatal by age 2-3 years, while late-onset forms progress more slowly. Hematopoietic stem cell transplantation, if performed before symptom onset, is the only disease-modifying therapy.
Documentation Requirements
- ✓Confirmed diagnosis of Krabbe disease or globoid cell leukodystrophy
- ✓Galactosylceramidase enzyme assay showing deficiency
- ✓GALC gene mutation analysis
- ✓Form specification: infantile, late infantile, juvenile, or adult onset
- ✓Brain MRI findings showing white matter changes
- ✓Nerve conduction studies documenting peripheral neuropathy
- ✓Treatment status including stem cell transplant consideration or completion
