Body mass index [BMI] 31.0-31.9, adult

This code signifies an adult patient with a Body Mass Index (BMI) falling within the range of 31.0 to 31.9. This BMI range is classified as obesity class I, indicating a moderate level of excess body fat. It is a key indicator for assessing a patient's weight status and associated health risks.

Use this code when a patient's BMI has been calculated and documented by a clinician as being between 31.0 and 31.9, inclusive. This is typically used during routine physical examinations, weight management clinic visits, or when obesity is a contributing factor to other health conditions. It should be reported as a secondary diagnosis when the BMI is not the primary reason for the encounter.

• Always ensure the BMI calculation is clearly documented in the medical record.
• Do not code BMI from patient self-reported weight/height; it must be clinician-measured.
• Report this code in conjunction with any associated obesity-related conditions (e.g., hypertension, diabetes).
