ICD-10 Code E34.328 – Other genetic causes of short stature (2026): Diagnosis, Symptoms & Billing Guide
2026 ICD-10-CM Diagnosis Code E34.328 – Other genetic causes of short stature
What it is
This code identifies short stature due to a genetic cause that is not named by a more specific diagnosis. Use it when documentation links reduced height to an inherited or chromosomal condition.
Clinical signs
Clinical features vary; refer to documentation. Commonly, you may see height below expected growth patterns, familial short stature, or a syndromic appearance when a genetic disorder is present.
When to use this code
Use E34.328 when the provider documents short stature as genetic and no more specific ICD-10-CM code applies. It may fit cases with confirmed hereditary etiology, genetic testing results, or specialist assessment naming an unspecified genetic cause.
Do not use it for short stature caused by endocrine disease, malnutrition, chronic illness, or constitutional delay unless the record clearly states a genetic basis.
Do not use for
Do not assign this code for nonspecific “short stature” without a genetic explanation. Check documentation if the cause is endocrine, nutritional, skeletal, or otherwise better described elsewhere.
Coding tip
Query for the exact genetic diagnosis when the record only says “genetic short stature,” because a more specific code may be available.
