Overweight Or Obesity – Definitions & ICD 11 Codes
Overweight or localised adiposity
Definition of Overweight or localised adiposity: Overweight is a condition characterized by excessive adiposity. Overweight is assessed by the body mass index (BMI), which is a surrogate marker of adiposity calculated as weight (kg)/height² (m²). The BMI categories for defining overweight vary by age and gender in infants, children and adolescents. For adults, overweight (or pre-obesity) is defined by a BMI ranging from 25.00 to 29.99 kg/m². Localized adiposity is a condition characterized by accumulation of adipose tissue in specific regions of the body independently of BMI.

5B80 Overweight or localised adiposity
5B80.0 Overweight
Definition of Overweight: Overweight is a condition characterized by excessive adiposity. Overweight is assessed by the body mass index (BMI), which is a surrogate marker of adiposity calculated as weight (kg)/height² (m²). The BMI categories for defining overweight vary by age and gender in infants, children and adolescents. For adults, overweight (or pre-obesity) is defined by a BMI ranging from 25.00 to 29.99 kg/m².
5B80.00 Overweight in infants children or adolescents
Definition of Overweight in infants children or adolescents: Overweight is a condition characterized by excessive adiposity. Overweight is assessed by the body mass index (BMI), which is a surrogate marker of adiposity calculated as weight (kg)/height² (m²). In infants, children and adolescents, BMI categories for defining overweight vary by age and gender based on WHO growth charts. Children 0 to 5 years are overweight if weight-for-length/height or BMI-for-age is above 2 and less than or equal to 3 standard deviations of the median of the WHO Child Growth Standards. Children 5 to 19 years are overweight if BMI-for-age is above 1 and less than or equal to 2 standard deviations of the median of WHO Growth Reference for School-aged Children and Adolescents .

Definition of Localised adiposity: A condition characterised by accumulation of adipose tissue in specific regions of the body.

Obesity
Definition of Obesity: Obesity is a chronic complex disease defined by excessive adiposity that can impair health. It is in most cases a multifactorial disease due to obesogenic environments, psycho-social factors and genetic variants. In a subgroup of patients, single major etiological factors can be identified (medications, diseases, immobilization, iatrogenic procedures, monogenic disease/genetic syndrome).
Body mass index (BMI) is a surrogate marker of adiposity calculated as weight (kg)/height² (m²). The BMI categories for defining overweight vary by age and gender in infants, children and adolescents. For adults, overweight is defined by a BMI greater than or equal to 30.00 kg/m². There are three levels of severity in recognition of different management options.

5B81.0 Obesity due to energy imbalance
Definition of Obesity due to energy imbalance: Obesity is a chronic complex disease defined by excessive adiposity that can impair health. It is in most cases a multifactorial disease due to obesogenic environments, psycho-social factors and genetic variants. In a subgroup of patients, single major etiological factors can be identified (diseases, immobilization, iatrogenic procedures, monogenic disease/genetic syndrome).
