Code Classification

  • Factors influencing health status and contact with health services
    (Z00–Z99)
    • Body mass index (Z68)
      (BMI)
      • Body mass index [BMI]
        (Z68)

Z68 is a non-specific and non-billable diagnosis code code, consider using a code with a higher level of specificity for a diagnosis of body mass index [bmi]. The code is not specific and is NOT valid for the year 2024 for the submission of HIPAA-covered transactions. Category or Header define the heading of a category of codes that may be further subdivided by the use of 4th, 5th, 6th or 7th characters.

Specific Coding Applicable to Body mass index [BMI]

Non-specific codes like Z68 require more digits to indicate the appropriate level of specificity. Consider using any of the following ICD-10-CM codes with a higher level of specificity when coding for body mass index [bmi]:

  • Use Z68.1 for Body mass index [BMI] 19.9 or less, adult - BILLABLE CODE

  • Z68.2 for Body mass index [BMI] 20-29, adult - NON-BILLABLE CODE

  • Use Z68.20 for Body mass index [BMI] 20.0-20.9, adult - BILLABLE CODE

  • Use Z68.21 for Body mass index [BMI] 21.0-21.9, adult - BILLABLE CODE

  • Use Z68.22 for Body mass index [BMI] 22.0-22.9, adult - BILLABLE CODE

  • Use Z68.23 for Body mass index [BMI] 23.0-23.9, adult - BILLABLE CODE

  • Use Z68.24 for Body mass index [BMI] 24.0-24.9, adult - BILLABLE CODE

  • Use Z68.25 for Body mass index [BMI] 25.0-25.9, adult - BILLABLE CODE

  • Use Z68.26 for Body mass index [BMI] 26.0-26.9, adult - BILLABLE CODE

  • Use Z68.27 for Body mass index [BMI] 27.0-27.9, adult - BILLABLE CODE

  • Use Z68.28 for Body mass index [BMI] 28.0-28.9, adult - BILLABLE CODE

  • Use Z68.29 for Body mass index [BMI] 29.0-29.9, adult - BILLABLE CODE

  • Z68.3 for Body mass index [BMI] 30-39, adult - NON-BILLABLE CODE

  • Use Z68.30 for Body mass index [BMI] 30.0-30.9, adult - BILLABLE CODE

Clinical Information

  • Body Mass Index

    an indicator of body density as determined by the relationship of body weight to body height. bmi=weight (kg)/height squared (m2). bmi correlates with body fat (adipose tissue). their relationship varies with age and gender. for adults, bmi falls into these categories: below 18.5 (underweight); 18.5-24.9 (normal); 25.0-29.9 (overweight); 30.0 and above (obese). (national center for health statistics, centers for disease control and prevention)

  • Obesity Paradox

    an observation that high body mass index is sometimes associated with lower cardiovascular disease mortality in certain population, e.g., elderly.

Inclusion Terms

Inclusion Terms
These terms are the conditions for which that code is to be used. The terms may be synonyms of the code title, or, in the case of "other specified" codes, the terms are a list of the various conditions assigned to that code. The inclusion terms are not necessarily exhaustive. Additional terms found only in the Alphabetic Index may also be assigned to a code.
  • Kilograms per meters squared

  • BMI adult codes are for use for persons 20 years of age or older
  • BMI pediatric codes are for use for persons 2-19 years of age.

Patient Education


Body Weight

Do you know if your current weight is healthy? "Underweight", "normal", "overweight", and "obese" are all labels for ranges of weight. Obese and overweight mean that your weight is greater than it should be for your health. Underweight means that it is lower than it should be for your health. Your healthy body weight depends on your sex and height. For children, it also depends on your age.

A sudden, unexpected change in weight can be a sign of a medical problem. Causes for sudden weight loss can include:

  • Thyroid problems
  • Cancer
  • Infectious diseases
  • Digestive diseases
  • Certain medicines

Sudden weight gain can be due to medicines, thyroid problems, heart failure, and kidney disease.

Good nutrition and exercise can help in losing weight. Eating extra calories within a well-balanced diet and treating any underlying medical problems can help to add weight.
