ICD-10 Code G62 – Other and unspecified polyneuropathies (2026): Diagnosis, Symptoms & Billing Guide
2026 ICD-10-CM Diagnosis Code G62 – Other and unspecified polyneuropathies
What it is
G62 is the ICD-10-CM code for polyneuropathy that is not otherwise specified or does not fit a more exact category. It covers peripheral nerve disorders affecting multiple nerves, with the exact cause left unspecified.
Clinical signs
Clinical features vary; refer to documentation. Commonly noted findings include symmetric sensory changes, numbness, tingling, weakness, or reduced reflexes in a stocking-glove pattern.
When to use this code
Use G62 when the provider documents polyneuropathy but does not identify a more specific type, cause, or subtype. It also fits when the record states other or unspecified polyneuropathy without further detail. Check documentation if diabetic, alcoholic, toxic, hereditary, or drug-induced neuropathy is mentioned, because those usually require a more specific code.
Do not use for
Do not use G62 for neuropathy with a clearly documented underlying cause that has its own code. Check documentation to avoid coding focal mononeuropathy or radiculopathy as polyneuropathy.
Coding tip
Code the most specific neuropathy documented, and use G62 only when the record truly remains nonspecific.
