E11.9 diagnosis code: Type 2 diabetes mellitus without complications
The E11.9 is an ICD code included in the International Classification of Diseases, Tenth Revision, Clinical Modification (ICD-10-CM), and it is used to designate “Type 2 diabetes mellitus without complications.”
Type 2 diabetes mellitus is a type of diabetes that normally occurs in middle-aged people or those in their late adulthood. The difference between Type 1 and Type 2 diabetes lies in the pancreas. For Type 1, the pancreas doesn't make insulin. For Type 2, the pancreas still makes insulin, but nowhere near as much as it normally does. Moreover, people with Type 2 diabetes become resistant to the effects of insulin.
This ICD-10 code is used to diagnose people with Type 2 diabetes mellitus, but the patient does not experience any complications that normally arise from this type of condition, such as heart disease, blood vessel disease, nerve damage, eye damage, and skin conditions.
