UCB recently engaged Milliman to estimate the distribution of patients with autoimmune encephalitis (AIE) or myelin oligodendrocyte glycoprotein antibody-associated disease (MOG-AD). AIE is a group of autoimmune disorders that affect the brain and cause inflammation of the brain. MOG-AD is a disorder caused by inflammatory attacks of the central nervous system. Milliman conducted a claims-based analysis for AIE, as well as a literature-based analysis for AIE and MOG-AD. The following payer channels are included in the analysis: 

• Medicare Fee-for-Service (FFS)
• Medicare Advantage
• Commercial
• Medicaid (FFS and managed care)
