G12.0:
- The most severe form of spinal muscular atrophy. It is manifested in the first year of life with muscle weakness, poor muscle tone, and lack of motor development. The motor neuron death affects the major organ systems, particularly the respiratory system. Most patients die before the age of two secondary to pneumonia.
ICD-10-CM G12.0 is grouped within Diagnostic Related Group(s) (MS-DRG v35.0):
- 056 Degenerative nervous system disorders with mcc
- 057 Degenerative nervous system disorders without mcc
