Other degenerative disorders of nervous system in diseases classified elsewhere (G32)

The ICD-10 codes under G32 classify various degenerative nervous system disorders that arise as part of other diseases. These codes help pinpoint nervous system damage linked to underlying conditions rather than standalone neurological diseases.

The code G32.0 covers subacute combined degeneration of the spinal cord, often caused by vitamin B12 deficiency, also known as myelopathy due to nutritional deficiency. Code G32.81 captures cerebellar ataxia associated with other diseases, including spinocerebellar ataxia caused by vitamin E deficiency or chemical exposure and complex syndromes such as amyotrophic lateral sclerosis with ataxia. Meanwhile, G32.89 accounts for various other specified degenerative nervous system conditions linked to systemic diseases, like encephalopathy from multiple nutrient deficiencies or cerebral degeneration due to hypothyroidism or neoplastic disease. Together, these codes serve to document nervous system degeneration that is secondary to broader medical issues, distinguishing them from primary neurological disorders. This distinction is important when searching for the ICD-10 code for specific conditions involving nervous system degeneration in the context of other illnesses.
