Understanding Obesity ICD 10

ICD-10, or the International Classification of Diseases (10th Revision). It is a coding system in medical field which is used globally to classify diseases and health conditions. In ICD-10, obesity is classified under the code E66, which falls under “Endocrine, nutritional and metabolic diseases” (E00-E89). This code is specifically used for Obesity, which provides a standardized way for healthcare professionals to record and communicate diagnoses related to obesity in medical records and billing. This is a vital tool for tracking and managing health conditions on global scale.

Exploring Obesity ICD 10

In ICD-10, obesity is classified using specific codes that provide information about the severity and type of obesity. The codes for obesity typically fall under the category of “E66” in the Obesity ICD 10 coding system. These codes are further divided to specify different types and degrees of obesity, such as:

  • E66.0: Obesity due to excess calories
  • E66.1: Drug-induced obesity
  • E66.2: Morbid (severe) obesity with alveolar hypoventilation
  • E66.3: Overweight
  • E66.8: Other obesity
  • E66.9: Obesity, unspecified

Classification of Classes of Obesity ICD 10

Obesity ICD 10 (Class Codes)BMI Range
Class 1 (E66.0)30.0 – 34.9
Class 2 (E66.1)35.0 – 39.9
Class 3 (E66.2)40.0 – 44.9
Class 4 (E66.3)45.0 – 49.9
Class 5 (E66.8)50.0 – 59.9
Class 6 (E66.9)60.0 and above

Understanding the Obesity ICD 10 Codes

Class 0 Obesity (E66.0): This is the category for people who have a BMI (Body Mass Index) that falls within the normal weight range. In other words, they are not considered obese.

Class 1 Obesity (E66.1): Individuals in this class have a BMI between 30.0 and 34.9. This is considered mild obesity.

Class 2 Obesity (E66.2): Class 2 obesity is also known as moderate obesity. It includes individuals with a BMI between 35.0 and 39.9.

Class 3 Obesity (E66.3): This is severe obesity, often referred to as morbid obesity. It includes individuals with a BMI of 40.0 or higher. Class 3 obesity is associated with a higher risk of health problems.

Class 4 Obesity (E66.8): This category includes individuals with a BMI greater than 50.0. It’s considered extreme or super obesity and is associated with significant health risks.

Class 5 Obesity (E66.9): Class 5 obesity is sometimes called super-super obesity. It includes individuals with a BMI greater than 60.0.

These classifications of Obesity ICD 10 are based on Body Mass Index (BMI). BMI is a concept in which a person’s weight and height is used through formula to caluculate obesity range. BMI is helpful for looking at weight on a big scale, like for a whole group of people. But it doesn’t think about differences in muscles, body type, and other things in individual people. Therefore, it is important to look at other signs of health and talk to a doctor to get a complete checkup of a person’s health and their chances of having obesity-related problems.
