Myelin Oligodendrocyte Glycoprotein Antibody Disease

Code G37.8, Other specified demyelinating diseases of central nervous system, was expanded to create new codes to identify myelin oligodendrocyte glycoprotein antibody disease (G37.81), and other specified demyelinating diseases of central nervous system (G37.89).Myelin oligodendrocyte glycoprotein antibody disease (MOG-AD) is a rare, antibody-mediated inflammatory demyelinating condition of the central nervous system. MOG-AD is characterized by attacks of immune-mediated demyelination predominantly targeting the optic nerves, brain, and spinal cord. The condition does not meet the diagnostic criteria for multiple sclerosis or other known neuroinflammatory conditions.MOG-AD occurs slightly more in women. Although it may occur in...
