Polyneuropathies and other disorders of the peripheral nervous system (G60-G65)

ICD-10 codes G60-G65 classify disorders affecting the peripheral nervous system, including hereditary, idiopathic, inflammatory, toxic, and sequelae of polyneuropathies. These codes are essential for identifying specific types of nerve damage involving multiple peripheral nerves.

The G60 series covers hereditary and idiopathic neuropathies, including many forms of Charcot-Marie-Tooth disease and other inherited sensory-motor neuropathies, often referred to by synonyms such as Déjérine-Sottas disease or hereditary sensory autonomic neuropathies. Codes like G61 describe inflammatory polyneuropathies, including Guillain-Barre syndrome and chronic inflammatory demyelinating polyneuritis, identified with alternative terms like autoimmune neuritis or Fisher's syndrome. The G62 range addresses toxic and drug-induced polyneuropathies, including neuropathies caused by chemotherapy agents or alcohol, also noting critical illness or radiation-induced polyneuropathy. Code G63 specifies polyneuropathy in systemic diseases such as diabetes or vitamin deficiencies, and G64 includes other peripheral nerve disorders like infections or acquired demyelinating conditions. Finally, G65 captures sequelae or long-term effects of inflammatory and toxic polyneuropathies, such as residual deficits from Guillain-Barre syndrome.

Instructional Notations

Type 1 Excludes

A type 1 excludes note is a pure excludes note. It means "NOT CODED HERE!" An Excludes1 note indicates that the code excluded should never be used at the same time as the code above the Excludes1 note. An Excludes1 is used when two conditions cannot occur together, such as a congenital form versus an acquired form of the same condition.
