Obesity, class 1

This code signifies a diagnosis of obesity where the patient's Body Mass Index (BMI) falls within the range of 30.0 to 34.9 kg/m². It indicates a moderate level of excess body fat that can contribute to various health complications.

Apply this code when a physician explicitly documents "obesity, class 1" or "BMI 30.0-34.9" in the patient's medical record. This diagnosis is typically made based on calculated BMI from documented height and weight measurements.

• Always ensure the physician's documentation clearly states "obesity, class 1" or provides the specific BMI range that corresponds to class 1.
• Do not code based solely on BMI without physician documentation of the obesity diagnosis.
• Consider sequencing this code after any related conditions that are a direct consequence of the obesity, if applicable.
