About coding Refsum's syndrome
The ICD-10-CM code for Refsum's syndrome is G60.1 (Refsum's disease).
Within G60 (hereditary and idiopathic neuropathy), G60.1 is specifically for Refsum's disease. Related codes cover hereditary motor and sensory neuropathy (G60.0), neuropathy in association with hereditary ataxia (G60.2), idiopathic progressive neuropathy (G60.3), other hereditary and idiopathic neuropathies (G60.8) and unspecified (G60.9).
As a secondary diagnosis it is a CC (complication or comorbidity), which can move an inpatient stay into the "with CC" MS-DRG of its family, unless the principal diagnosis excludes it.
In MS-DRG v44.0, it is part of the grouping logic for DRG 091 (Other Disorders of Nervous System with MCC, relative weight 1.7046), DRG 092 (Other Disorders of Nervous System with CC, relative weight 1.0239) and DRG 093 (Other Disorders of Nervous System without CC/MCC, relative weight 0.7783), 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.
