ICD-10 Code G65.2 – Sequelae of Toxic Polyneuropathy (2026): Diagnosis, Symptoms & Billing Guide
2026 ICD-10-CM Diagnosis Code G65.2 – Sequelae of toxic polyneuropathy
What it is
G65.2 identifies lingering nerve damage after a toxic polyneuropathy has already occurred. Use it when the current problem is a residual effect, not the active poisoning or exposure.
Clinical signs
Findings commonly include persistent numbness, tingling, weakness, or sensory loss after the toxic cause has resolved. Clinical features vary; refer to documentation.
When to use this code
Use this code when the record states the patient has ongoing neurologic deficits due to a prior toxic polyneuropathy. It applies to late effects rather than the acute toxic episode. Confirm that the provider documents sequelae or residual neuropathy.
Do not use for
Do not use this code for active toxic polyneuropathy, current poisoning, or neuropathy from another cause. Check documentation if the record does not clearly link the nerve disorder to a prior toxic event.
Coding tip
Code the residual condition only when the sequela is documented, and sequence any current cause or exposure first if it is still being treated.
