What This Code Means

This code describes a person who is naturally very tall due to their genetic makeup or constitutional factors, rather than due to a disease or medical condition. It's used when someone's height is simply part of their normal physical development.

Coding Tips

• •This is a benign condition and should not be confused with pathological causes of tall stature such as gigantism or acromegaly, which have different codes
• •Verify documentation clearly indicates constitutional (genetic/familial) tall stature rather than height related to endocrine disorders or other medical conditions

Clinical Significance

Constitutional tall stature is a normal variant where an individual's height exceeds the 97th percentile due to genetic and familial factors rather than pathological causes. While not a disease per se, documentation of this condition helps differentiate benign tall stature from pathological causes such as Marfan syndrome, Klinefelter syndrome, or growth hormone excess that require different management approaches.

Documentation Requirements

• ✓Documentation should include the patient's height, height percentile for age, growth velocity, parental heights and target height calculation, and bone age assessment.
• ✓The provider should explicitly state that tall stature is constitutional in nature and document the exclusion of pathological causes including Marfan syndrome, homocystinuria, growth hormone excess, and chromosomal abnormalities.
