About G62.2

G62.2 is the ICD-10-CM diagnosis code for polyneuropathy due to other toxic agents. 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 billable, so it can be reported on its own for dates of service from October 1, 2026 through September 30, 2027.

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

Code first: (T51-T65) to identify toxic agent.

It is not a CC or MCC, so as a secondary diagnosis it doesn't change the MS-DRG severity level.

In MS-DRG v44.0, it is part of the grouping logic for DRG 073 (Cranial and Peripheral Nerve Disorders with MCC, relative weight 1.5779) and DRG 074 (Cranial and Peripheral Nerve Disorders without MCC, relative weight 1.0173), in MDC 01 (Diseases and Disorders of the Nervous System), as a principal or secondary diagnosis. The DRG a claim lands in depends on the principal diagnosis, procedures and any CC/MCC secondary diagnoses.

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

Before ICD-10, this condition was coded in ICD-9-CM as 357.7 (polyneuropathy due to other toxic agents).
