About coding Morvan's disease
The ICD-10-CM code for Morvan's disease is G60.8 (Other hereditary and idiopathic neuropathies).
Within G60, choose G60.8 (Other hereditary and idiopathic neuropathies) only when documentation doesn't support a more specific option: hereditary motor and sensory neuropathy (G60.0), Refsum's disease (G60.1), neuropathy in association with hereditary ataxia (G60.2), idiopathic progressive neuropathy (G60.3) 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.
