“Morbid Obesity” has always been supported by BMI values of 40 or more or 35-39.9 with co-morbid conditions and “Overweight” has always been supported by BMI values of 30-34.99 supports.

In ICD 10, when coding from category E66, there is an instructional note to use additional code to identify the BMI, if known.

Is it appropriate to report E66.01 (Morbid Obesity) with a documented BMI of 34.0? Does a BMI of 34.9 and below support the definition of morbid obesity?
