G37.9 - Demyelinating disease of central nervous system, unspecified
| ICD-10: | G37.9 |
| Short Description: | Demyelinating disease of central nervous system, unspecified |
| Long Description: | Demyelinating disease of central nervous system, unspecified |
| Status: | Valid for Submission |
| Version: | ICD-10-CM 2023 |
| Code Classification: |
G37.9 is a billable ICD-10 code used to specify a medical diagnosis of demyelinating disease of central nervous system, unspecified. The code is valid during the fiscal year 2023 from October 01, 2022 through September 30, 2023 for the submission of HIPAA-covered transactions.
Unspecified diagnosis codes like G37.9 are acceptable when clinical information is unknown or not available about a particular condition. Although a more specific code is preferable, unspecified codes should be used when such codes most accurately reflect what is known about a patient's condition. Specific diagnosis codes should not be used if not supported by the patient's medical record.

Degenerative Nerve Diseases
Degenerative nerve diseases affect many of your body's activities, such as balance, movement, talking, breathing, and heart function. Many of these diseases are genetic. Sometimes the cause is a medical condition such as alcoholism, a tumor, or a stroke. Other causes may include toxins, chemicals, and viruses. Sometimes the cause is unknown.
Degenerative nerve diseases include:
- Alzheimer's disease
- Amyotrophic lateral sclerosis
- Friedreich ataxia
- Huntington's disease
- Lewy body disease
- Parkinson's disease
- Spinal muscular atrophy
Degenerative nerve diseases can be serious or life-threatening. It depends on the type. Most of them have no cure. Treatments may help improve symptoms, relieve pain, and increase mobility.
