Type 1 diabetes mellitus is a condition where the pancreas beta cells are destroyed due to autoimmune mechanisms or viral infections, resulting in the inability to produce insulin. The Korean government implements various support programs to aid in the health management of type 1 diabetes patients. To address some shortcomings and adapt to diverse needs arising from advancements in diabetes management device technology, related policies were revised starting on February 26, 2024. Key updates include application of the criteria for continuous glucose monitoring system sensors to users of sensoraugmented pumps and establishing consumable material subsidies for users of closed-loop insulin pumps who are younger than 19 years. Support amounts vary based on the type of insulin pump, which vary by application. Additionally, to enhance diabetes education for pediatric and adolescent patients and their families, insulin pump education is newly introduced, along with an expansion of educational counseling sessions. These policies may further aid in patients’ blood glucose management, with hopes for continued expansion of support in the future.
