Body mass index [BMI] 50.0-59.9, adult

This diagnosis code indicates an adult patient with a Body Mass Index (BMI) falling within the range of 50.0 to 59.9 kg/m². This BMI range signifies severe obesity, often referred to as morbid obesity, and is associated with a significantly increased risk of various health complications.

This code is used when a clinician documents an adult patient's BMI as being between 50.0 and 59.9, inclusive. It is typically assigned as a secondary diagnosis to support the medical necessity of services related to obesity management or when obesity is a contributing factor to other medical conditions.

• Always ensure the patient's age is documented as an adult, as BMI codes vary for pediatric patients.
• This code should be sequenced after the primary diagnosis for which the patient is being treated, unless the obesity itself is the primary reason for the encounter.
• Verify that the BMI calculation is clearly documented in the patient's medical record to support the code assignment.
