ICD-10 Code G60.3 – Idiopathic progressive neuropathy (2026): Diagnosis, Symptoms & Billing Guide
2026 ICD-10-CM Diagnosis Code G60.3 – Idiopathic progressive neuropathy
What it is
G60.3 identifies a progressive neuropathy with no known cause. Use it when documentation describes an idiopathic, worsening peripheral nerve disorder.
Clinical signs
Clinical features vary; refer to documentation. Commonly recorded findings include slowly progressive sensory loss, weakness, reduced reflexes, or distal nerve dysfunction without an identified underlying condition.
When to use this code
Use G60.3 when the provider documents idiopathic progressive neuropathy, or a progressive neuropathy of unknown cause after evaluation. It fits cases where the record supports peripheral nerve disease but does not name a specific etiology. If the cause is known, code the underlying condition instead.
Do not use for
Do not use this code for neuropathy with a documented cause, such as diabetes, alcohol use, toxins, or hereditary disease. Check documentation if the record describes a different neuropathy type or a focal nerve lesion.
Coding tip
Code G60.3 only when the provider clearly states idiopathic and progressive; otherwise, query or check documentation for a more specific diagnosis.
