ICD-10 Code G62.0 – Drug-induced polyneuropathy (2026): Diagnosis, Symptoms & Billing Guide
2026 ICD-10-CM Diagnosis Code G62.0 – Drug-induced polyneuropathy
What it is
G62.0 identifies polyneuropathy caused by a medication or other drug exposure. Use it when documentation links the nerve disorder directly to the drug effect.
Clinical signs
Typical findings include symmetric sensory symptoms such as numbness, tingling, burning pain, and reduced reflexes. Weakness, gait difficulty, or distal sensory loss may also appear; clinical features vary, refer to documentation.
When to use this code
Use G62.0 when the provider documents drug-induced polyneuropathy, toxic neuropathy from a medication, or neuropathy due to an adverse drug effect. Code the condition only when the causal relationship is stated or clearly supported in the record. If the record names the drug, capture it as directed by coding guidelines.
Do not use for
Do not use this code for neuropathy with no documented drug cause or for hereditary, diabetic, or alcoholic neuropathy. Check documentation when the etiology is unclear.
Coding tip
Look for the specific drug and the provider’s causal wording; without that link, you should not assign G62.0.
