Diabetes Mellitus – Definitions & ICD 11 Codes
Definition of Diabetes Mellitus: A metabolic disorder with heterogenous aetiologies which is characterised by chronic hyperglycaemia and disturbances of carbohydrate, fat and protein metabolism resulting from defects in insulin secretion, insulin action, or both.
Coded Elsewhere:
- Diabetes mellitus in pregnancy (JA63)
- Neonatal diabetes mellitus (KB60.2)
Type 1 diabetes mellitus
Definition of Type 1 diabetes mellitus: Diabetes mellitus type 1 (type 1 diabetes, T1DM, formerly insulin dependent or juvenile diabetes) is a form of diabetes mellitus that results from destruction of insulin-producing beta cells, mostly by autoimmune mechanisms. The subsequent lack of insulin leads to increased blood and urine glucose.

Exclusions:
- Type 2 diabetes mellitus (5A11)
- Diabetes mellitus, other specified type (5A13)
- Diabetes mellitus in pregnancy (JA63)
Coded Elsewhere:
- Pre-existing type 1 diabetes mellitus in pregnancy (JA63.0)
Type 2 diabetes mellitus
Definition of Type 2 diabetes mellitus: Diabetes mellitus type 2 (formerly noninsulin-dependent diabetes mellitus (NIDDM) or adult-onset diabetes) is a metabolic disorder that is characterised by high blood glucose in the context of insulin resistance and relative insulin deficiency.
ICD 11 Codes For Type 2 diabetes mellitus
5A11 Type 2 diabetes mellitus
Inclusions:
- non-insulin-dependent diabetes of the young
Exclusions:
- Diabetes mellitus in pregnancy (JA63)

ICD 11 Codes For Malnutrition-related diabetes mellitus
5A12 Malnutrition-related diabetes mellitus
Diabetes mellitus other specified type
ICD 11 Codes For Diabetes mellitus other specified type
5A13 Diabetes mellitus other specified type
Definition of Diabetes mellitus other specified type: Diabetes mellitus which cannot be classified as either Type 1 or Type 2 diabetes mellitus.
Exclusions:
- Diabetes mellitus in pregnancy (JA63)
- Type 2 diabetes mellitus (5A11)
- Idiopathic Type 1 diabetes mellitus (5A10)
5A13.0 Diabetes mellitus due to genetic defects of beta cell function
Definition of Diabetes mellitus due to genetic defects of beta cell function: Other specified diabetes mellitus due to genetic defects of beta cell function is a form of diabetes, which is associated with monogenetic defects in beta-cell function.
5A13.1 Diabetes mellitus due to genetic defects in insulin action
Definition of Diabetes mellitus due to genetic defects in insulin action: Other specified diabetes mellitus due to genetic defects in insulin action is a form of diabetes, which results from genetically determined abnormalities of insulin action. The metabolic abnormalities associated with mutations of the insulin receptor may range from hyperinsulinemia and modest hyperglycaemia to severe diabetes.
5A13.2 Diabetes mellitus due to diseases of the exocrine pancreas
Definition of Diabetes mellitus due to diseases of the exocrine pancreas: Other specified diabetes mellitus due to diseases of the exocrine pancreas is a form of diabetes, which caused by any process that diffusely injures the pancreas. Acquired processes include pancreatitis, trauma, infection, pancreatectomy, and pancreatic carcinoma. With the exception of that caused by cancer, damage to the pancreas must be extensive for diabetes to occur.
5A13.3 Diabetes mellitus due to endocrinopathies
Definition of Diabetes mellitus due to endocrinopathies: Other specified diabetes mellitus due to endocrinopathies is a form of diabetes caused by several hormones (e.g., growth hormone, cortisol, glucagon, epinephrine), which antagonize insulin action. Excess amounts of these hormones (e.g., acromegaly, Cushing’s syndrome, glucagonoma, pheochromocytoma, respectively) can cause diabetes. This generally occurs in individuals with preexisting defects in insulin secretion, and hyperglycaemia typically resolves when the hormone excess is resolved.
5A13.4 Diabetes mellitus due to drug or chemical
Definition of Diabetes mellitus due to drug or chemical: Other specified diabetes mellitus due to drug or chemical is a form of diabetes, which is caused by drug or chemical substance that impairs insulin secretion and insulin action.
5A13.5 Diabetes mellitus due to uncommon forms of immune-mediated diabetes
Definition of Diabetes mellitus due to uncommon forms of immune-mediated diabetes: Other specified diabetes mellitus due to uncommon forms of immune-mediated diabetes is a form of diabetes, which is caused by two known conditions. The stiff-man syndrome is an autoimmune disorder of the central nervous system characterised by stiffness of the axial muscles with painful spasms. Patients usually have high titres of the GAD autoantibodies, and approximately one-third will develop diabetes.
5A13.6 Diabetes mellitus due to other genetic syndromes
Definition of Diabetes mellitus due to other genetic syndromes: Other specified diabetes mellitus due to other genetic syndromes is a form of diabetes, which is associated with genetic syndromes.
Coding Note:
- Use additional code, if desired, to identify any associated genetic syndrome
Coded Elsewhere:
- Wolfram syndrome (5A61.5)
- Maternally inherited diabetes and deafness (LD2H.Y)
- Thiamine-responsive megaloblastic anaemia syndrome (5C63.Y)
- Woodhouse-Sakati syndrome (5A61.0)
- Mitochondrial myopathy with diabetes mellitus (8C73.Y)

Definition of Diabetes mellitus due to clinically defined subtypes or syndromes: Diabetes mellitus that has clinically defined subtypes or associated syndromes
5A13.Y Diabetes mellitus due to other specified cause
