2021 ICD-10-CM Codes for Type 2 diabetes mellitus (E11)

Clinical Terms for Type 2 diabetes mellitus (E11)

Diabetes Mellitus, Type 2-. A subclass of DIABETES MELLITUS that is not INSULIN-responsive or dependent (NIDDM). It is characterized initially by INSULIN RESISTANCE and HYPERINSULINEMIA; and eventually by GLUCOSE INTOLERANCE; HYPERGLYCEMIA; and overt diabetes. Type II diabetes mellitus is no longer considered a disease exclusively found in adults. Patients seldom develop KETOSIS but often exhibit OBESITY.
