ICD-10 Code E34.329 – Unspecified Genetic Causes of Short Stature (2026): Diagnosis, Symptoms & Billing Guide
2026 ICD-10-CM Diagnosis Code E34.329 – Unspecified genetic causes of short stature
What it is
This code identifies short stature that is believed to have a genetic cause, but the specific inherited disorder or gene change is not documented. Use it when the chart supports a genetic explanation without a more precise diagnosis.
Clinical signs
Clinical features vary; refer to documentation. Common findings may include height below expected age norms, slowed linear growth, or a family history suggesting inherited short stature.
When to use this code
Use this code when the provider documents short stature with a suspected or known genetic basis, but the condition is not further specified. It may fit cases where genetic testing is incomplete, pending, or nondiagnostic. Code only what is clearly supported in the record.
Do not use for
Do not use this code for short stature from endocrine disease, chronic illness, malnutrition, or constitutional delay unless the record specifically supports a genetic cause. Check documentation if the cause is unclear.
Coding tip
If the note names a specific syndrome or gene-related disorder, code that diagnosis instead of this unspecified category.
