About coding hereditary neuropathy
The ICD-10-CM code for hereditary neuropathy is G60.9 (Hereditary and idiopathic neuropathy, unspecified). The official index lists 3 more specific codes, so check the documentation for details such as type, cause, site or severity before settling on G60.9.
Within G60, choose G60.9 (unspecified) 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 other hereditary and idiopathic neuropathies (G60.8).
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.
