ICD-10 Code E34.4 – Constitutional tall stature (2026): Diagnosis, Symptoms & Billing Guide
2026 ICD-10-CM Diagnosis Code E34.4 – Constitutional tall stature
What it is
Constitutional tall stature describes a person who is taller than expected for age and family pattern without evidence of disease. Use this code when the height pattern is considered normal variation rather than a pathologic overgrowth disorder.
Clinical signs
Typical findings include height above expected percentiles, often with a proportionate body build and otherwise normal development. Clinical features vary; refer to documentation.
When to use this code
Use E34.4 when the provider documents constitutional or familial tall stature as the diagnosis and no underlying endocrine, genetic, or skeletal cause is identified. It may apply during routine growth evaluation or specialist assessment of unusually tall height. Code only when the record clearly supports a nonpathologic explanation.
Do not use for
Do not assign this code for tall stature caused by a known disorder, such as endocrine disease, genetic syndrome, or medication effect. Check documentation if the chart suggests overgrowth, abnormal proportions, or another specific diagnosis.
Coding tip
Confirm that the clinician has ruled out a secondary cause before coding E34.4.
