The guideline states **“do not assign BMI codes during pregnancy.” **A female of normal weight at conception that gains the recommended 25 to 35 pounds during the pregnancy will have a BMI that measures in the overweight range at the time of delivery. This is not a true reflection of the patient being overweight or having too much body fat.   ## What is BMI in Adults? This is the body mass (weight) divided by the body height and is expressed in units kg/m2. The BMI is used to determine the amount of tissue mass (muscle, fat and bone) in a person. This is then used to help determine if a person is underweight, normal weight, overweight, or obese. The BMI can be used to screen for body fat but is not diagnostic. These values are different depending on the population (such as the Asian population vs. European). ### Common BMI Ranges: - **Underweight** is under 18.5 kg/m2 - **Normal weight** is 18.5 to 25 kg/m2 - **Overweight** is 25 to 30 kg/m2 - **Obese** is over 30 kg/m2 ## Common Diseases Associated with High BMI (Overweight/Obese): - Hypertension - Type 2 diabetes mellitus - Coronary artery disease - Stroke - Sleep apnea - Hyperlipidemia - Osteoarthritis or general body pain - Depression - Low quality of life - Malignancy *Authored by Kim Boy, RHIT, CDIP, CCS, CCS-P* **References** [wikipedia.org/wiki/Body_mass_index](https://en.wikipedia.org/wiki/Body_mass_index) [cdc.gov/healthyweight/assessing/bmi/adult_bmi/index.html](https://www.cdc.gov/healthyweight/assessing/bmi/adult_bmi/index.html) [mayoclinic.org/healthy-lifestyle/pregnancy-week-by-week/in-depth/pregnancy-weight-gain/art-20044360](https://www.mayoclinic.org/healthy-lifestyle/pregnancy-week-by-week/in-depth/pregnancy-weight-gain/art-20044360) AHA Coding Clinic for ICD-10-CM/PCS, Fourth Quarter 2018 Page: 80 --- For the past 30 years, HIA has been the leading provider of [compliance audits](https://hiacode.com/acute-review), [coding support services](https://hiacode.com/acute-coding-support) and [clinical documentation audit services ](https://hiacode.com/clinical-documentation-integrity)for hospitals, [ambulatory surgery centers](https://hiacode.com/asc-coding), physician groups and other healthcare entities.
