About M34.83

M34.83 is the ICD-10-CM diagnosis code for systemic sclerosis with polyneuropathy. It belongs to category M34 (systemic sclerosis [scleroderma]), block M30-M36 (systemic connective tissue disorders) and chapter 13 (diseases of the musculoskeletal system and connective tissue). It is billable, so it can be reported on its own for dates of service from October 1, 2026 through September 30, 2027.

Within M34.8 (other forms of systemic sclerosis), M34.83 is specifically for systemic sclerosis with polyneuropathy. Related codes cover systemic sclerosis with lung involvement (M34.81), systemic sclerosis with myopathy (M34.82) and other systemic sclerosis (M34.89).

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 357.4 (polyneuropathy in other diseases classified elsewhere) and 710.1 (systemic sclerosis).
