What is the ICD-10 code E66?
The ICD-10 code E66 is obesity. Obesity is a condition in which a person has an excessively high amount of body fat.

What is the ICD 10 Code For Obesity?
The ICD 10 Code for Obesity is E66. Obesity is a condition in which a person has an abnormally high body mass index (BMI). BMI is a measure of body fat based on height and weight. A BMI of 30 or above is considered obese. Obesity increases the risk of many health problems, including heart disease, stroke, diabetes, and joint problems.
How is Obesity Diagnosed?
There are a few different ways that doctors can diagnose obesity. One way is to calculate someone’s body mass index (BMI). BMI is a number that is calculated using someone’s height and weight. A BMI of 30 or above is considered obese. Another way to diagnose obesity is to measure someone’s waist circumference. This is because excess belly fat is linked with more health risks than fat in other parts of the body. A waist circumference of 40 inches or more for men and 35 inches or more for women is considered obese.
Another test that might be done is called a DXA scan. This uses X-rays to measure bone density and body fat percentage. Doctors might also order blood tests to look for problems that can be caused by obesity, such as high cholesterol or insulin resistance. In some cases, doctors might also do genetic testing to look for genes that are linked with obesity.
The Different Types of Obesity
There are three main types of obesity:
- Excess body fatness: This is when someone has a body mass index (BMI) of 30 or more. This type of obesity is often caused by eating too much and not getting enough exercise.
- Central or abdominal obesity: This is when someone has a lot of extra fat around their waist. This type of obesity is often linked to health problems like heart disease and diabetes.
- Extreme or morbid obesity: This is when someone has a BMI of 40 or more. Morbid obesity can lead to serious health problems, and it is often hard to treat.
Causes of Obesity
There are a variety of reasons why someone might be obese. The most common cause is simply eating too much and not getting enough exercise.
Other causes can include:
- A slow metabolism
- Hormonal problems
- Certain medications
- Genetics
If you think you might be obese, it’s important to talk to your doctor. They can help you determine if there is a medical reason for your weight gain and develop a plan to help you lose weight if necessary.
Health Risks Associated with Obesity
There are many health risks associated with obesity. These include heart disease, stroke, type 2 diabetes, sleep apnea, fatty liver disease, and certain types of cancer.
Obesity is also associated with a number of psychological problems, such as depression and low self-esteem. In addition, obese individuals are more likely to suffer from social isolation and discrimination.
Treatment for Obesity
There are many different ways to treat obesity, and the most effective method will vary from person to person. Some common methods include lifestyle changes (such as diet and exercise), medication, and surgery.
Lifestyle changes: Making small changes to your diet and activity level can have a big impact on your weight. Even modest weight loss can improve your health.
Medication: If lifestyle changes alone aren’t enough to help you lose weight, your doctor may prescribe medication. Several types of drugs are available, and they all work in different ways.
Surgery: In some cases, surgery may be an option. Surgery is usually only recommended for people who are very obese and who haven’t been able to lose weight through other means.
