Part B Coding Coach: Use BMI and Overweight/Obesity Dx to Determine Correct ICD-10 Code

Why This Topic Matters

BMI and weight-status documentation are common in preventive and problem-oriented visits, and incorrect reporting can affect claim accuracy and record integrity. Understanding the documentation requirements helps coding professionals avoid unsupported code assignment and align records with ICD-10-CM guidance.
