Code Classification

  • Endocrine, nutritional and metabolic diseases
    (E00–E89)
    • Diabetes mellitus
      (E08-E13)
      • Type 1 diabetes mellitus
        (E10)

E10.9 is a billable diagnosis code used to specify a medical diagnosis of type 1 diabetes mellitus without complications. The code is valid during the current fiscal year for the submission of HIPAA-covered transactions from October 01, 2023 through September 30, 2024.

The code is commonly used in pediatrics medical specialties to specify clinical concepts such as diabetes mellitus.

The code is linked to some Quality Measures as part of Medicare's Quality Payment Program (QPP). When this code is used as part of a patient's medical record the following Quality Measures might apply: Diabetes: Hemoglobin A1c (hba1c) Poor Control (>9%) , Diabetes: Eye Exam.

Clinical Information

  • Diabetes Complications

    conditions or pathological processes associated with the disease of diabetes mellitus. due to the impaired control of blood glucose level in diabetic patients, pathological processes develop in numerous tissues and organs including the eye, the kidney, the blood vessels, and the nerve tissue.
  • Diabetes Mellitus

    a heterogeneous group of disorders characterized by hyperglycemia and glucose intolerance.
  • Diabetes Mellitus, Experimental

    diabetes mellitus induced experimentally by administration of various diabetogenic agents or by pancreatectomy.
  • Diabetes Mellitus, Lipoatrophic

    a type of diabetes mellitus that is characterized by severe insulin resistance and lipodystrophy. the latter may be generalized, partial, acquired, or congenital (lipodystrophy, congenital generalized).
  • Diabetes Mellitus, Type 1

    a subtype of diabetes mellitus that is characterized by insulin deficiency. it is manifested by the sudden onset of severe hyperglycemia, rapid progression to diabetic ketoacidosis, and death unless treated with insulin. the disease may occur at any age, but is most common in childhood or adolescence.
  • 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.
  • Diabetes, Gestational

    diabetes mellitus induced by pregnancy but resolved at the end of pregnancy. it does not include previously diagnosed diabetics who become pregnant (pregnancy in diabetics). gestational diabetes usually develops in late pregnancy when insulin antagonistic hormones peaks leading to insulin resistance; glucose intolerance; and hyperglycemia.
  • Latent Autoimmune Diabetes in Adults

    autoimmune diabetes in adults with slowly progressive pancreatic beta cell failure and the presence of circulating autoantibodies to pancreatic islets cell antigens.
  • Polyendocrinopathies, Autoimmune

    autoimmune diseases affecting multiple endocrine organs. type i is characterized by childhood onset and chronic mucocutaneous candidiasis (candidiasis, chronic mucocutaneous), while type ii exhibits any combination of adrenal insufficiency (addison's disease), lymphocytic thyroiditis (thyroiditis, autoimmune;), hypoparathyroidism; and gonadal failure. in both types organ-specific antibodies against a variety of endocrine glands have been detected. the type ii syndrome differs from type i in that it is associated with hla-a1 and b8 haplotypes, onset is usually in adulthood, and candidiasis is not present.
  • Pancreatectomy

    surgical removal of the pancreas. (dorland, 28th ed)

Coding Guidelines

The diabetes mellitus codes are combination codes that include the type of diabetes mellitus, the body system affected, and the complications affecting that body system. As many codes within a particular category as are necessary to describe all of the complications of the disease may be used. They should be sequenced based on the reason for a particular encounter. Assign as many codes from categories E08 - E13 as needed to identify all of the associated conditions that the patient has.

The age of a patient is not the sole determining factor, though most type 1 diabetics develop the condition before reaching puberty. For this reason type 1 diabetes mellitus is also referred to as juvenile diabetes.

Quality Payment Program Measures

When code E10.9 is part of the patient's diagnoses the following Quality Measures apply and affect reimbursement. The objective of Medicare's Quality Measures is to improve patient care by making it more: effective, safe, efficient, patient-centered and equitable.

Patient Education


Diabetes Type 1

Diabetes means your blood glucose, or blood sugar, levels are too high. With type 1 diabetes, your pancreas does not make insulin. Insulin is a hormone that helps glucose get into your cells to give them energy. Without insulin, too much glucose stays in your blood. Over time, high blood glucose can lead to serious problems with your heart, eyes, kidneys, nerves, and gums and teeth.

Type 1 diabetes happens most often in children and young adults but can appear at any age. Symptoms may include:

  • Being very thirsty
  • Urinating often
  • Feeling very hungry or tired
  • Losing weight without trying
  • Having sores that heal slowly
  • Having dry, itchy skin
  • Losing the feeling in your feet or having tingling in your feet
  • Having blurry eyesight

A blood test can show if you have diabetes. If you do, you will need to take insulin for the rest of your life. A blood test called the A1C can check to see how well you are managing your diabetes.

Type 1 diabetes

Type 1 diabetes is a disorder characterized by abnormally high levels of blood glucose, also called blood sugar. In this form of diabetes, specialized cells in the pancreas called beta cells stop producing insulin. Insulin controls how much glucose (a type of sugar) is passed from the blood into cells for conversion to energy. Lack of insulin results in the inability to use glucose for energy or to control the amount of glucose in the blood.

Type 1 diabetes can occur at any age, from early childhood to late adulthood. The first signs and symptoms of the disorder are caused by high blood glucose and may include frequent urination (polyuria), excessive thirst (polydipsia), fatigue, blurred vision, tingling or loss of feeling in the hands and feet, and weight loss. These symptoms may recur during the course of the disorder if blood glucose is not well controlled by insulin replacement therapy. Improper control can also cause blood glucose levels to become too low (hypoglycemia). This may occur when the body's needs change, such as during exercise or if eating is delayed. Hypoglycemia can cause headache, dizziness, hunger, shaking, sweating, weakness, and agitation.

Uncontrolled type 1 diabetes can lead to a life-threatening complication called diabetic ketoacidosis. Without insulin, cells cannot take in glucose. A lack of glucose in cells prompts the liver to try to compensate by releasing more glucose into the blood, and blood glucose can become extremely high. The cells, unable to use the glucose in the blood for energy, respond by using fats instead. Breaking down fats to obtain energy produces waste products called ketones, which can build up to toxic levels in people with type 1 diabetes, resulting in diabetic ketoacidosis. Affected individuals may begin breathing rapidly; develop a fruity odor in the breath; and experience nausea, vomiting, facial flushing, stomach pain, and dryness of the mouth (xerostomia). In severe cases, diabetic ketoacidosis can lead to coma and death.

Over many years, the chronic high blood glucose associated with diabetes may cause damage to blood vessels and nerves, leading to complications affecting many organs and tissues. The retina, which is the light-sensitive tissue at the back of the eye, can be damaged (diabetic retinopathy), leading to vision loss and eventual blindness. Kidney damage (diabetic nephropathy) may also occur and can lead to kidney failure and end-stage renal disease (ESRD). Pain, tingling, and loss of normal sensation (diabetic neuropathy) often occur, especially in the feet. Impaired circulation and absence of the normal sensations that prompt reaction to injury can result in permanent damage to the feet; in severe cases, the damage can lead to amputation. People with type 1 diabetes are also at increased risk of heart attacks, strokes, and problems with urinary and sexual function.
