ICD-10 code for MOGAD

The ICD-10-CM code for MOGAD is G37.81 (Myelin oligodendrocyte glycoprotein antibody disease).

Within G37.8 (other specified demyelinating diseases of central nervous system), G37.81 is specifically for Myelin oligodendrocyte glycoprotein antibody disease. Related codes cover other specified demyelinating diseases of central nervous system (G37.89).

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 058 (Multiple Sclerosis and Cerebellar Ataxia with MCC, relative weight 1.8438), DRG 059 (Multiple Sclerosis and Cerebellar Ataxia with CC, relative weight 1.2002) and DRG 060 (Multiple Sclerosis and Cerebellar Ataxia without CC/MCC, relative weight 0.9247), 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.
