G32: ICD10 Code for Other degenerative disorders of nervous system in diseases classified elsewhere

G32 refers to Other degenerative disorders of nervous system in diseases classified elsewhere, a set of progressive neurodegenerative disorders that affect the brain’s structure and function. These disorders lead to cognitive decline, memory loss, personality changes, and motor or autonomic dysfunction depending on the condition.

Symptoms

• Memory impairment – Hallmark of Alzheimer’s disease (G30)
• Personality and behavioral changes – Often seen in frontotemporal dementia (G31)
• Coordination or balance issues – May appear in G32 degenerative syndromes linked to systemic illness
• Difficulty with problem-solving or abstract thinking – Common in all degenerative CNS disorders
• Disorientation – Frequently worsens with disease progression
• Language difficulties – Including word-finding problems or reduced fluency
• Loss of independence – Due to cognitive or neurological decline

Diagnosis

Diagnosis of Other degenerative disorders of nervous system in diseases classified elsewhere includes cognitive testing (e.g., MMSE, MoCA), MRI or CT brain imaging, neurological exams, lab work to exclude other causes, and sometimes PET scans or CSF biomarkers. A thorough clinical history is essential to distinguish among neurodegenerative diseases.

ICD10 Code Usage

ICD10 code G32 is widely used in neurology, geriatrics, psychiatry, and long-term care settings. It supports dementia care planning, diagnostic documentation, clinical trials, insurance processing, and multidisciplinary intervention for neurodegenerative decline.

Related Codes

• G30 – Alzheimer's disease
• G31 – Other degenerative diseases of nervous system, not elsewhere classified

FAQs

Q1: What is ICD10 code G32?
A: It classifies Other degenerative disorders of nervous system in diseases classified elsewhere, a neurodegenerative condition that progressively impairs cognitive, behavioral, or motor function depending on its etiology.

Q2: Is Alzheimer’s disease (G30) curable?
A: No, it is a chronic and progressive illness, but symptom progression can be slowed with medications and cognitive support.

Q3: What is the difference between G31 and G32?
A: G31 covers degenerative CNS disorders not linked to systemic diseases; G32 applies when the condition is secondary to another disease like HIV or multiple sclerosis.

Q4: How are these conditions treated?
A: Treatment includes cholinesterase inhibitors, NMDA receptor antagonists, behavioral therapy, caregiver education, and occupational support.

Q5: Who manages these disorders?
A: Neurologists, geriatricians, psychiatrists, primary care physicians, and dementia care teams.

Conclusion

ICD10 code G32 plays a vital role in diagnosing and managing Other degenerative disorders of nervous system in diseases classified elsewhere, ensuring coordinated care, accurate documentation, and access to appropriate therapies and support systems for patients and caregivers.
