ICD-10 Code G62.2 – Polyneuropathy due to other toxic agents (2026): Diagnosis, Symptoms & Billing Guide
2026 ICD-10-CM Diagnosis Code G62.2 – Polyneuropathy due to other toxic agents
What it is
G62.2 identifies a peripheral polyneuropathy caused by exposure to toxic agents other than alcohol, drugs, or heavy metals specifically coded elsewhere. It means multiple peripheral nerves are affected by a toxic injury.
Clinical signs
Typical findings include symmetric numbness, tingling, burning pain, or weakness in the hands and feet. Clinical features vary; refer to documentation and the recorded toxic exposure or suspected cause.
When to use this code
Use G62.2 when the provider documents polyneuropathy attributed to a toxic substance and no more specific code applies. This is appropriate when the record links nerve damage to a nonalcohol, non-drug toxic exposure. If the toxin is identified elsewhere in coding guidance, follow that instruction instead.
Do not use for
Do not use this code for neuropathy from diabetes, alcohol, or medication effects coded to a different category. Also avoid it when documentation does not clearly support a toxic cause; check documentation.
Coding tip
Confirm the exact toxic exposure in the note, because the cause may require a more specific code or additional external-cause documentation.
