About G62.8

G62.8 is the ICD-10-CM diagnosis code for other specified polyneuropathies. It belongs to category G62 (other and unspecified polyneuropathies), block G60-G65 (polyneuropathies and other disorders of the peripheral nervous system) and chapter 6 (diseases of the nervous system). It is a header code, so it can't be reported by itself; one of its 3 subcodes must be used instead.

Within G62, choose G62.8 (Other specified polyneuropathies) only when documentation doesn't support a more specific option: drug-induced polyneuropathy (G62.0), alcoholic polyneuropathy (G62.1), polyneuropathy due to other toxic agents (G62.2) and polyneuropathy, unspecified (G62.9).

To report this condition, pick the subcode that matches the documentation: G62.81 (polyneuropathy), G62.82 (polyneuropathy) and G62.89 (polyneuropathies).

It has been part of ICD-10-CM since the code set took effect on October 1, 2015 and hasn't changed since.
