2025 ICD-10-CM Diagnosis Code E11.10

Approximate Synonyms

The following list of clinical terms are approximate synonyms, alternative descriptions, or common phrases that might be used by patients, healthcare providers, or medical coders to describe the same condition. These synonyms and related diagnosis terms are often used when searching for an ICD-10 code, especially when the exact medical terminology is unclear. Whether you're looking for lay terms, similar diagnosis names, or common language alternatives, this list can help guide you to the correct ICD-10 classification.

Clinical Classification

Clinical Classifications group individual ICD-10-CM diagnosis codes into broader, clinically meaningful categories. These categories help simplify complex data by organizing related conditions under common clinical themes.

They are especially useful for data analysis, reporting, and clinical decision-making. Even when diagnosis codes differ, similar conditions can be grouped together based on their clinical relevance. Each category is assigned a unique CCSR code that represents a specific clinical concept, often tied to a body system or medical specialty.

Clinical Information

• Diabetic Ketoacidosis

  a life-threatening complication of diabetes mellitus, primarily of type 1 diabetes mellitus with severe insulin deficiency and extreme hyperglycemia. it is characterized by ketosis; dehydration; and depressed consciousness leading to coma.

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.

If the type of diabetes mellitus is not documented in the medical record the default is E11.-, Type 2 diabetes mellitus.

MS-DRG Mapping for ICD-10-CM Code E11.10

Diagnosis-Related Groups (DRGs) are used to classify hospital cases for billing and healthcare management. They help standardize how hospitals and other providers are reimbursed for inpatient care. Patients are grouped based on their principal diagnosis into broader categories called Major Diagnostic Categories (MDCs).

Once assigned to a DRG, the hospital receives a set payment for the patient’s care, regardless of the actual services provided. This fixed rate is intended to cover the typical cost of treating patients within that group. The payment amount depends on the DRG's relative weight, which reflects the expected complexity and cost of care based on the severity of the patient’s condition.

Diagnostic related groups encourage healthcare providers to focus on quality and efficiency in patient care while managing costs effectively. The diagnosis code is present in the following groups for version MS-DRG V42.0 applicable from 10/01/2024 through 09/30/2025.

Replacement Code

E1110 replaces the following previously assigned ICD-10-CM code(s):

• E11.69 - Type 2 diabetes mellitus with other specified complication

Convert E11.10 to ICD-9-CM

Below are the ICD-9 codes that most closely match this ICD-10 code, based on the General Equivalence Mappings (GEMs). This ICD-10 to ICD-9 crosswalk tool is helpful for coders who need to reference legacy diagnosis codes for audits, historical claims, or approximate code comparisons.

Diabetes Type 2

What is type 2 diabetes?

Type 2 diabetes is a disease in which your blood glucose, or blood sugar, levels are too high. Glucose is your main source of energy. It comes from the foods you eat. A hormone called insulin helps the glucose get into your cells to give them energy. If you have diabetes, your body doesn't make enough insulin or doesn't use insulin well. The glucose then stays in your blood and not enough goes into your cells.

Over time, having too much glucose in your blood can cause health problems. But you can take steps to manage your diabetes and try to prevent these health problems.

What causes type 2 diabetes?

Type 2 diabetes may be caused by a combination of factors:

• Being overweight or having obesity
• Not being physically active
• Genetics and family history

Type 2 diabetes usually starts with insulin resistance. This is a condition in which your cells don't respond normally to insulin. As a result, your body needs more insulin to help the glucose enter your cells. At first, your body makes more insulin to try to get cells to respond. But over time, your body can't make enough insulin, and your blood glucose levels rise.

Who is at risk for type 2 diabetes?

You are at higher risk of developing type 2 diabetes if you:

• Are over age 45. Children, teenagers, and younger adults can get type 2 diabetes, but it is more common in middle-aged and older people.
• Have prediabetes, which means that your blood sugar is higher than normal but not high enough to be called diabetes
• Had diabetes in pregnancy or gave birth to a baby weighing 9 pounds or more.
• Have a family history of diabetes
• Are overweight or have obesity
• Are Black or African American, Hispanic/Latino, American Indian, Asian American, or Pacific Islander
• Are not physically active
• Have other conditions such as high blood pressure, heart disease, stroke, polycystic ovary syndrome (PCOS), or depression
• Have low HDL (good) cholesterol and high triglycerides
• Have acanthosis nigricans - dark, thick, and velvety skin around your neck or armpits

What are the symptoms of type 2 diabetes?

Many people with type 2 diabetes have no symptoms at all. If you do have them, the symptoms develop slowly over several years. They might be so mild that you do not notice them. The symptoms can include:

• Increased thirst and urination
• Increased hunger
• Feeling tired
• Blurred vision
• Numbness or tingling in the feet or hands
• Sores that do not heal
• Unexplained weight loss

How is type 2 diabetes diagnosed?

Your health care provider will use blood tests to diagnose type 2 diabetes. The blood tests include:

• A1C test, which measures your average blood sugar level over the past 3 months
• Fasting plasma glucose (FPG) test, which measures your current blood sugar level. You need to fast (not eat or drink anything except water) for at least 8 hours before the test.
• Random plasma glucose (RPG) test, which measures your current blood sugar level. This test is used when you have diabetes symptoms and the provider does not want to wait for you to fast before having the test.

What are the treatments for type 2 diabetes?

Treatment for type 2 diabetes involves managing your blood sugar levels. Many people are able to do this by living a healthy lifestyle. Some people may also need to take medicine.:

• A healthy lifestyle includes following a healthy eating plan and getting regular physical activity. You need to learn how to balance what you eat and drink with physical activity and diabetes medicine, if you take any.
• Medicines for diabetes include oral medicines, insulin, and other injectable medicines. Over time, some people will need to take more than one type of medicine to control their diabetes.
• You will need to check your blood sugar regularly. Your health care provider will tell you how often you need to do it.
• It's also important to keep your blood pressure and cholesterol levels close to the targets your provider sets for you. Make sure to get your screening tests regularly.

Can type 2 diabetes be prevented?

You can take steps to help prevent or delay type 2 diabetes by losing weight if you are overweight, eating fewer calories, and being more physically active. If you have a condition which raises your risk for type 2 diabetes, managing that condition may lower your risk of getting type 2 diabetes.
