ICD-10 Code G62.82 – Radiation-induced polyneuropathy (2026): Diagnosis, Symptoms & Billing Guide
2026 ICD-10-CM Diagnosis Code G62.82 – Radiation-induced polyneuropathy
What it is
G62.82 identifies polyneuropathy caused by prior radiation therapy. Use it when documentation links peripheral nerve damage to radiation exposure rather than another cause.
Clinical signs
Clinical features vary; refer to documentation. Typical findings may include symmetric numbness, tingling, weakness, or sensory loss in the affected limbs, with a history of radiation to the involved area.
When to use this code
Use this code when the provider documents radiation-induced polyneuropathy, radiation neuropathy, or nerve injury attributed to radiotherapy. It may also fit follow-up visits for persistent neuropathic deficits after cancer treatment. Check documentation if the cause is unclear or if another neuropathy is specified.
Do not use for
Do not use it for neuropathy from diabetes, chemotherapy, alcohol, or other non-radiation causes. If the record does not clearly connect the neuropathy to radiation, check documentation.
Coding tip
Link the neuropathy to the radiation history in the note; without that connection, you should code the documented neuropathy cause instead.
