About the E65–E68 Code Range
ICD-10 codes E65-E68 cover conditions related to excess body fat, including overweight, various types of obesity, and complications from excessive nutrition known as hyperalimentation. These codes distinguish specific causes and severities, helping to accurately categorize these nutritional disorders.
This range includes E65 for localized adiposity, which refers to excess fat accumulation in specific body areas, also called fat pad syndrome or insulin lipohypertrophy. Codes under E66 address overweight and obesity, detailing causes like excess calorie intake (E66.0), drug-induced obesity (E66.1), and morbid obesity with complications such as alveolar hypoventilation (E66.2). Notably, E66.01 specifies morbid (severe) obesity, also known as obese class III. The code E66.3 captures overweight status, including increased body mass index (BMI 25-29). Other obesity types and classes (1-3) are listed with precise codes (E66.8, E66.81 series). The E67 codes relate to hyperalimentation conditions from excessive vitamin or nutrient intake, such as hypervitaminosis A (E67.0), D (E67.3), and vitamin B6 overdose (E67.2). Lastly, E68 addresses sequelae of hyperalimentation, including resultant myelopathy or anemia. These codes assist healthcare professionals in documenting and managing nutritional excesses and their specific health impacts.
