Final answer:
The correct ICD-10-CM code for obesity with a BMI of 32.5 is within the E66.- range, and specifically, Z68.32 is used to indicate a BMI of 32.5. Although the patient is obese, they are not classified as morbidly obese, which is defined in ICD-10-CM as a BMI of 40 or above.
Step-by-step explanation:
The correct ICD-10-CM code for a 30-year-old obese patient with a BMI of 32.5 would fall under the range of codes for obesity, specifically E66.- for 'Overweight and obesity.' Given that a BMI of 30 or higher is considered obese, this patient would likely be classified within the code range E66.0-E66.9 which covers various types of obesity. However, for accurate coding, a specific code from this range is selected based on further details, and supplementary codes can also be used to specify the BMI. For a BMI of 32.5, the relevant BMI specific ICD-10-CM code would be Z68.32. A combination of codes from the E66.- range and Z68.32 should be provided to fully represent the patient's condition. While the patient's BMI of 32.5 does classify them as obese, they are not considered to be morbidly obese as this condition applies to BMIs of 40 or more. Morbid obesity is associated with more severe health risks and is indicated differently in ICD-10-CM coding.
