G62: ICD10 Code for Other and unspecified polyneuropathies

G62 refers to Other and unspecified polyneuropathies, a group of conditions involving damage to multiple peripheral nerves. These neuropathies can be inherited, caused by autoimmune inflammation, systemic illness, or toxic exposure, and often lead to functional impairments and chronic discomfort.

Symptoms

• Numbness or tingling in hands and feet – A hallmark of polyneuropathy
• Burning or stabbing pain – Frequently seen in G60 and G61 neuropathies
• Muscle weakness – Progressive in hereditary or inflammatory forms
• Loss of reflexes – Noted in advanced polyneuropathies (G62, G63)
• Difficulty walking or balance issues – Especially in long-standing cases
• Autonomic dysfunction – Including changes in heart rate, sweating, or digestion (often in G64)
• Residual neuropathy symptoms – Persisting after recovery in G65 cases

Diagnosis

Diagnosis of Other and unspecified polyneuropathies includes nerve conduction studies, EMG, genetic testing (for hereditary forms), lumbar puncture (in GBS-type G61), lab tests for systemic conditions (e.g., diabetes, B12 deficiency), and MRI in selected cases. Thorough neurological exam is key.

ICD10 Code Usage

ICD10 code G62 is used in neurology, rehabilitation medicine, internal medicine, and primary care. It supports classification of neuropathies for treatment planning, insurance billing, disability assessments, and long-term monitoring of nerve-related dysfunction.

Related Codes

• G60 – Hereditary and idiopathic neuropathy
• G61 – Inflammatory polyneuropathy
• G63 – Polyneuropathy in diseases classified elsewhere
• G64 – Other disorders of peripheral nervous system
• G65 – Sequelae of inflammatory and toxic polyneuropathies

FAQs

Q1: What is ICD10 code G62?
A: It identifies Other and unspecified polyneuropathies, a disorder involving multiple peripheral nerves with symptoms ranging from numbness to motor weakness.

Q2: Are these conditions permanent?
A: Some hereditary and toxic neuropathies are chronic, but inflammatory forms like GBS may be reversible with early treatment.

Q3: What causes polyneuropathy?
A: Causes include genetics, autoimmune disease, diabetes, toxins, nutritional deficiencies, or secondary systemic illnesses.

Q4: What treatments are available?
A: Immunotherapy (for G61), pain management, physiotherapy, assistive devices, and treatment of underlying conditions.

Q5: Who manages these disorders?
A: Neurologists, physiatrists, pain specialists, endocrinologists, and physical therapists.

Conclusion

ICD10 code G62 plays a crucial role in diagnosing and documenting Other and unspecified polyneuropathies. Early identification enables timely intervention, management of symptoms, and access to therapies that can improve function and quality of life.
