ICD-10 Code G62.8 – Other specified polyneuropathies (2026): Diagnosis, Symptoms & Billing Guide
2026 ICD-10-CM Diagnosis Code G62.8 – Other specified polyneuropathies
What it is
This code identifies polyneuropathy that is documented but does not fit a more specific ICD-10 category. Use it when the record names a distinct peripheral nerve disorder and the provider specifies another cause or type.
Clinical signs
Clinical features vary; refer to documentation. Commonly reported findings include symmetric sensory or motor deficits, numbness, tingling, weakness, or reduced reflexes affecting multiple peripheral nerves.
When to use this code
Use G62.8 when the clinician documents a polyneuropathy that is not captured by diabetic, drug-induced, hereditary, or other listed categories. It is appropriate when the chart states “other specified polyneuropathy” or gives a specific neuropathy type not indexed elsewhere. Check documentation for the exact cause and whether a more specific code exists.
Do not use for
Do not use this code if the neuropathy is better described by a more specific ICD-10 code, such as diabetic or alcoholic polyneuropathy. Do not assign it for nonspecific neuropathy when the record lacks a clear diagnosis.
Coding tip
Always confirm that the provider’s wording supports “other specified” rather than an unspecified or more specific polyneuropathy code.
