About G60.3

G60.3 is the ICD-10-CM diagnosis code for idiopathic progressive neuropathy. It belongs to category G60 (hereditary and idiopathic neuropathy), 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 G60 (hereditary and idiopathic neuropathy), G60.3 is specifically for idiopathic progressive neuropathy. Related codes cover hereditary motor and sensory neuropathy (G60.0), Refsum's disease (G60.1), neuropathy in association with hereditary ataxia (G60.2), other hereditary and idiopathic neuropathies (G60.8) and unspecified (G60.9).

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 356.4 (idiopathic progressive polyneuropathy).
