ICD-10 Code G62.89 – Other specified polyneuropathies (2026): Diagnosis, Symptoms & Billing Guide
2026 ICD-10-CM Diagnosis Code G62.89 – Other specified polyneuropathies
What it is
G62.89 identifies polyneuropathy when the nerve disorder is documented but does not fit a more specific ICD-10-CM category. Use it for peripheral nerve disease affecting multiple nerves when the record names another specified cause or type.
Clinical signs
Clinical features vary; refer to documentation. Common findings in polyneuropathy include symmetric sensory changes, numbness, tingling, pain, weakness, or reduced reflexes, but the chart should support the specific diagnosis.
When to use this code
Use this code when the clinician documents a polyneuropathy that is specified but not otherwise classified in ICD-10-CM. It is appropriate when the record supports peripheral nerve involvement and no more precise code is available. Check documentation if the cause, pattern, or subtype is unclear.
Do not use for
Do not use G62.89 when the record clearly supports a more specific polyneuropathy code, such as diabetic, drug-induced, or inflammatory neuropathy. Also avoid it for isolated mononeuropathy or nonspecific neuropathic pain without a documented polyneuropathy.
Coding tip
Code the most specific documented neuropathy first, and query the provider if the note does not clearly identify the type or cause.
