ICD-10 Code G62.9 – Polyneuropathy, unspecified (2026): Diagnosis, Symptoms & Billing Guide
2026 ICD-10-CM Diagnosis Code G62.9 – Polyneuropathy, unspecified
What it is
G62.9 identifies polyneuropathy when the provider documents nerve damage affecting multiple peripheral nerves but does not specify the cause or type. Use it when the record supports polyneuropathy, unspecified.
Clinical signs
Clinical features vary; refer to documentation. Common findings may include symmetric numbness, tingling, burning pain, weakness, or reduced reflexes in more than one peripheral nerve distribution.
When to use this code
Use G62.9 when the clinician diagnoses polyneuropathy and does not document a more specific etiology, such as diabetic, toxic, or hereditary disease. It also fits when the note confirms neuropathy in multiple peripheral nerves but lacks further detail. Check documentation if the cause is stated elsewhere in the chart.
Do not use for
Do not use this code for mononeuropathy, radiculopathy, or a clearly documented specific polyneuropathy type. If another cause or subtype is documented, code that condition instead.
Coding tip
Query the provider when the record says only “neuropathy” and does not confirm multiple peripheral nerves or specify a cause.
