ICD-10: Z68.5

The ICD-10 code Z68.5 pertains to Body Mass Index (BMI) for pediatric patients, and it encompasses a range of specific codes that categorize BMI percentiles for children and adolescents aged 2 to 19. Here are some alternative names and related terms associated with this code:

• BMI Pediatric Codes: This refers to the specific codes used to report BMI in children, which include:
• Z68.51: BMI pediatric, less than 5th percentile for age.
• Z68.52: BMI pediatric, 5th percentile to less than 85th percentile for age.
• Z68.53: BMI pediatric, 85th percentile to less than 95th percentile for age.

• Z68.54: BMI pediatric, 95th percentile for age to less than 120% of the 95th percentile for age [3][4][6].

• Pediatric BMI Percentiles: This term refers to the classification of BMI based on percentiles, which helps in assessing whether a child is underweight, normal weight, overweight, or obese.

• WHO Classification: The World Health Organization (WHO) provides guidelines and classifications for BMI, which are utilized in the ICD-10 coding system.

• Secondary Codes: The pediatric BMI codes (Z68.51–Z68.54) are considered secondary codes and should be reported alongside findings of underweight, overweight, or obesity [5][6].

These terms and classifications are essential for healthcare providers to accurately document and assess the nutritional status of pediatric patients.

The ICD-10 code Z68.5 pertains to Body Mass Index (BMI) for pediatric patients, specifically for individuals aged 2 to 19 years. The criteria for diagnosis using this code are based on the BMI percentiles for children and adolescents. Here are the key points regarding the criteria:

• Age Range: The Z68.5 code is specifically for pediatric patients, which includes individuals from 2 to 19 years of age [2][6].

• BMI Percentiles: The diagnosis is determined by comparing a child's BMI to established percentiles for their age and sex. The relevant codes for pediatric BMI include:

• Z68.51: BMI less than the 5th percentile for age.
• Z68.52: BMI from the 5th percentile to less than the 85th percentile for age.
• Z68.53: BMI from the 85th percentile to less than the 95th percentile for age.
• Z68.54: BMI at the 95th percentile for age to less than 120% of the 95th percentile for age.

• Z68.55: BMI at or above 120% of the 95th percentile for age [3][4][5][6].

• Clinical Assessment: The assessment involves measuring the child's height and weight to calculate the BMI, which is then compared against the growth charts that provide the percentiles based on age and sex [6].

• Additional Notes: The coding guidelines have been updated to support the reporting of pediatric BMI, ensuring that healthcare providers can accurately document and address weight-related health issues in children [7].

These criteria are essential for healthcare providers to diagnose and manage weight-related health conditions in pediatric patients effectively.
