Defining Presymptomatic Diabetes Mellitus

Subcategory E10.A, Type 1 diabetes mellitus, presymptomatic, has been created with new codes to capture distinct stages of presymptomatic type 1 diabetes (T1D) mellitus.

Presymptomatic T1D consists of the presence of islet autoantibodies or biomarkers that attack islet autoantigens, such as insulin-producing beta cells in the pancreas. Multiple islet autoantibodies increase the risk of developing symptomatic T1D by 100% within a lifetime.
