ICD-10-CM Code G31.9
Degenerative disease of nervous system, unspecified
Billable Code
Billable codes are sufficient justification for admission to an acute care hospital when used a principal diagnosis.G31.9 is a billable ICD code used to specify a diagnosis of degenerative disease of nervous system, unspecified. A 'billable code' is detailed enough to be used to specify a medical diagnosis.
The ICD code G31 is used to code Neurodegeneration
Neurodegeneration is the umbrella term for the progressive loss of structure or function of neurons, including death of neurons. Many neurodegenerative diseases including amyotrophic lateral sclerosis, Parkinson's, Alzheimer's, and Huntington's occur as a result of neurodegenerative processes. Such diseases are incurable, resulting in progressive degeneration and/or death of neuron cells. As research progresses, many similarities appear that relate these diseases to one another on a sub-cellular level. Discovering these similarities offers hope for therapeutic advances that could ameliorate many diseases simultaneously. There are many parallels between different neurodegenerative disorders including atypical protein assemblies as well as induced cell death. Neurodegeneration can be found in many different levels of neuronal circuitry ranging from molecular to systemic.

Equivalent ICD-9 Codes GENERAL EQUIVALENCE MAPPINGS (GEM)
This is the official approximate match mapping between ICD9 and ICD10, as provided by the General Equivalency mapping crosswalk. This means that while there is no exact mapping between this ICD10 code G31.9 and a single ICD9 code, 331.9 is an approximate match for comparison and conversion purposes.
