2024 ICD-10-CM Diagnosis Code E10.65

Approximate Synonyms

The following clinical terms are approximate synonyms or lay terms that might be used to identify the correct diagnosis code:

• Hyperglycemia due to diabetes mellitus
• Hyperglycemia due to type 1 diabetes mellitus

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.

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.

Hyperglycemia

What is blood glucose?

Blood glucose, or blood sugar, is the main sugar found in your blood. It is your body's primary source of energy. It comes from the food you eat. Your body breaks down most of that food into glucose and releases it into your bloodstream. When your blood glucose goes up, it signals your pancreas to release insulin. Insulin is a hormone that helps the glucose get into your cells to be used for energy.

For people with diabetes, your body doesn't make enough insulin, can't use it as well as it should, or both. Too much glucose stays in your blood and doesn't reach your cells.

What is hyperglycemia?

Hyperglycemia means high blood glucose. It most often affects people who have diabetes. When you have diabetes, your body doesn't make enough insulin or can't use it the right way. Too much glucose stays in your blood and doesn't reach your cells.

What causes hyperglycemia?

A key part of managing diabetes is controlling your blood glucose levels. To do this, you need to follow a diabetes meal plan and get regular physical activity. You might also need to take diabetes medicines. You have to balance all of these to keep your blood glucose at the right levels. But if you eat too much food or the wrong foods, don't take your medicines correctly, or don't get physical activity, you can get hyperglycemia. It can also happen if you are stressed or sick.

Less commonly, people who don't have diabetes can also get hyperglycemia. It can be caused by conditions that can affect insulin or glucose levels in your blood. They include problems with your pancreas or adrenal glands, certain medicines, and severe illnesses.

What are the symptoms of hyperglycemia?

The symptoms of hyperglycemia include:

• Feeling thirsty
• Feeling tired or weak
• Headaches
• Urinating (peeing) often
• Blurred vision

If you are diabetic and you often have high blood glucose levels or the symptoms of hyperglycemia, talk with your health care team. You may need a change in your diabetes meal plan, physical activity plan, or diabetes medicines.

If you don't have diabetes and you are having these symptoms, see your provider to find out the cause and how to treat it.

What other problems can hyperglycemia cause?

If hyperglycemia is not treated, it can cause other problems. In people with diabetes, long-term hyperglycemia can lead to serious health problems (diabetes complications).

If your blood glucose levels get very high, you can develop diabetes-related ketoacidosis (DKA). It happens when your body doesn't have enough insulin to allow blood glucose into your cells for use as energy. Instead, your liver breaks down fat for fuel. This process produces acids called ketones. When too many ketones are produced too fast, they can build up to dangerous levels in your body. This can be life-threatening.

The symptoms of DKA may include:

• Trouble breathing
• Nausea or vomiting
• Pain in your abdomen (belly)
• Confusion
• Feeling very tired or sleepy

If you have an an at-home test for ketones, check your ketone level every 4 to 6 hours when your blood glucose is very high or when you are having these symptoms. If the test shows that your ketones are moderate or high, or if you don't have a ketones test, contact your health care provider right away or get emergency medical help.

How is hyperglycemia diagnosed?

If you have diabetes, you'll most likely need to check your blood glucose every day and make sure that it's not too high. You can do this with a blood glucose meter or continuous glucose monitoring (CGM) system.

There are also blood tests that providers can use to check if your blood glucose is too high.

What are the treatments for hyperglycemia?

If you have diabetes and often have high blood glucose, your health care team may make changes to your diabetes meal plan, physical activity plan, and/or diabetes medicines.

If you have severe hyperglycemia and are having symptoms of DKA, you will need treatment at the hospital. The treatment often includes I.V. (intravenous) fluids and insulin.

Can hyperglycemia be prevented?

If you have diabetes, managing your diabetes can help prevent hyperglycemia. To manage your diabetes, it's important to:

• Follow your diabetes meal plan
• Get regular physical activity
• If you need diabetes medicines, take them correctly
• Regularly check your blood glucose level
• Get regular checkups with your health care team

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.
