International Classification of Diseases

Last updated: 10/3/2025

What is a ICD-10 Code?

ICD-10 (International Classification of Diseases, 10th Revision) codes are used to classify and code all diagnoses, symptoms, and procedures recorded in association with hospital care. These codes provide a standardized way to track health conditions and their treatment outcomes.

Detailed Description

This code is used by healthcare providers to document that your Body Mass Index (BMI) falls between 33.0 and 33.9. BMI is a measurement that uses your height and weight to estimate body fat and assess whether you're in a healthy weight range. A BMI in this range (33.0-33.9) is classified as Class II obesity, which means you have a significantly higher risk for health problems like diabetes, heart disease, high blood pressure, and sleep apnea. This code helps your doctor track your weight status over time and may be used to support medical necessity for weight management treatments, nutritional counseling, or other obesity-related interventions. It's important to discuss with your healthcare provider about healthy lifestyle changes and treatment options that may be appropriate for you.

Additional Information

This is a documentation code only - no procedure is performed. The code supports medical necessity for obesity treatment and helps track patient health status over time. BMI 33.0-33.9 represents Class II obesity with significant health risks.
