Body mass index [BMI] 45.0-49.9, adult

This code signifies severe obesity in adult patients, specifically when their Body Mass Index (BMI) falls within the range of 45.0 to 49.9 kg/m². This BMI range indicates a significant amount of excess body fat, placing individuals at a higher risk for various health complications.

Apply this code when a physician's documentation clearly states an adult patient's BMI is between 45.0 and 49.9. This is commonly seen in encounters for weight management, bariatric surgery evaluations, or when obesity is a contributing factor to other medical conditions.

• Always ensure the BMI is explicitly documented by a provider, not just calculated from height and weight.
• Code this in conjunction with any associated obesity-related comorbidities (e.g., type 2 diabetes, hypertension).
• Do not use this code for pediatric patients; specific pediatric BMI codes exist.
