Morbid Obesity BMI Classification
Morbid obesity is classified as class III (“extreme”/“severe”) obesity with a BMI ≥ 40 kg/m². [1]
BMI Cutoff Definition
- BMI ≥ 40 kg/m² defines morbid obesity. [1]
Related Obesity Category Nomenclature
- Morbid obesity is commonly mapped to class III obesity in clinical and policy documents. [1]
Assessment Basis
- BMI is calculated as weight (kg) / height (m²). [2]
Clinical Coding Implication
- Terminology “morbid obesity” corresponds to a BMI threshold at which severity-based clinical management pathways may apply. [1]
Measurement Prerequisites
- Accurate height and weight measurement is required to classify BMI-based obesity severity categories. [2]
Units and Rounding
- The cutoff is specified in kg/m² at 40 for the morbid obesity classification threshold. [1]
