Body mass index [BMI] 34.0-34.9, adult

This code indicates an adult patient has a Body Mass Index (BMI) falling within the range of 34.0 to 34.9 kg/m². This BMI range is classified as Class I obesity, signifying a significant amount of excess body fat that can increase health risks.

This code is used when documenting a patient's BMI measurement that falls specifically between 34.0 and 34.9, inclusive, for individuals 20 years of age or older. It is often reported as a secondary diagnosis to provide context for other obesity-related conditions or for routine health screenings.

• Always ensure the patient's age is 20 years or older for adult BMI codes.
• Report this code as a secondary diagnosis; it is rarely a primary reason for an encounter.
• Confirm the exact BMI calculation from the medical record to select the most specific code.
