Trisomy 18, unspecified
ICD-10 Q91.3 is a billable code used to indicate a diagnosis of trisomy 18, unspecified.
Trisomy 18, also known as Edwards syndrome, is a chromosomal abnormality characterized by the presence of an extra 18th chromosome. This condition leads to severe developmental delays and a range of congenital malformations. Infants with Trisomy 18 often present with low birth weight, a small head (microcephaly), a prominent back of the head, and a clenched fist with overlapping fingers. Other common features include heart defects, kidney abnormalities, and gastrointestinal issues. The prognosis for infants with Trisomy 18 is generally poor, with many not surviving past their first year of life. Diagnosis is typically made through prenatal screening and confirmed via genetic testing. The condition is associated with advanced maternal age and is not inherited in most cases. Management focuses on supportive care and addressing specific medical issues as they arise.
