ICD-10 Code G60.9 – Hereditary and idiopathic neuropathy, unspecified (2026): Diagnosis, Symptoms & Billing Guide
2026 ICD-10-CM Diagnosis Code G60.9 – Hereditary and idiopathic neuropathy, unspecified
What it is
G60.9 identifies a neuropathy that is either inherited or has no known cause, when the specific type is not documented. Use it for generalized peripheral nerve disease without a more precise hereditary or idiopathic diagnosis.
Clinical signs
Clinical features vary; refer to documentation. Common findings may include sensory loss, numbness, tingling, weakness, or reduced reflexes affecting peripheral nerves, but the record should support a neuropathy diagnosis.
When to use this code
Use this code when the provider documents hereditary neuropathy or idiopathic neuropathy but does not name a more specific subtype. It also fits when the chart confirms peripheral neuropathy and no cause is identified after evaluation. If the documentation later specifies a distinct disorder, code that condition instead.
Do not use for
Do not use G60.9 for neuropathy with a known cause, such as diabetes, alcohol use, medication, or trauma. Check documentation if the record names a specific inherited syndrome or a more precise neuropathy type.
Coding tip
Code G60.9 only when the provider clearly documents hereditary or idiopathic neuropathy and no more specific code is available.
