Other genetic causes of short stature

This code signifies short stature resulting from an underlying genetic etiology not specifically classified elsewhere. It encompasses a range of inherited conditions or chromosomal abnormalities that directly impair growth, leading to a height significantly below the average for age and sex.

Apply this code when documentation clearly indicates a genetic cause for short stature, such as specific genetic syndromes (e.g., Noonan syndrome, Silver-Russell syndrome) or chromosomal disorders, that do not have a more specific ICD-10-CM code. Supporting documentation should include genetic testing results, clinical geneticist's reports, or detailed physician notes outlining the genetic diagnosis.

• Ensure the documentation explicitly states a genetic cause; avoid using this code for idiopathic short stature or short stature due to endocrine disorders.
• Always sequence this code after the definitive genetic syndrome or chromosomal abnormality code, if one exists and is more specific.
• Do not use this code if a more specific code for a known genetic short stature syndrome (e.g., Turner syndrome, Down syndrome) is available.
