ICD-10 code for polyneuropathy
From the official ICD-10-CM alphabetic index entry “Polyneuropathy (peripheral)”. Page updated September 29, 2026.
About coding polyneuropathy
The ICD-10-CM code for polyneuropathy is G62.9 (Polyneuropathy, unspecified). The official index lists 77 more specific codes, so check the documentation for details such as type, cause, site or severity before settling on G62.9.
Within G62, choose G62.9 (Polyneuropathy, unspecified) 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 other specified polyneuropathies (G62.8).
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.
