Obesity, class 2

This code identifies a patient with obesity classified as Class II, indicating a Body Mass Index (BMI) between 35.0 and 39.9 kg/m². This level of obesity is associated with increased health risks and often requires medical intervention for weight management and comorbidity treatment.

Apply this code when documentation clearly states a diagnosis of Class II obesity or a BMI calculation falls within the 35.0-39.9 range. This is appropriate for patients undergoing weight loss programs, bariatric surgery evaluations, or management of obesity-related comorbidities. Ensure the BMI is documented or calculable from documented height and weight.

• Always document the patient's BMI or sufficient information (height and weight) to calculate it.
• Do not code this if the patient has morbid (Class III) obesity (BMI $\ge$ 40.0), which has a separate code.
• Sequence this code as a secondary diagnosis when another condition is the primary reason for the encounter, unless obesity is the primary reason for the visit.
